Overview =========== QGIS, like a number of major projects (eg. KDE 4.0), uses CMake (http://www.cmake.org) for building from source. Following a summary of the required dependencies for building: Required build tools: - CMake >= 2.6.0 - Flex - Bison Required build deps: - Qt >= 4.4.0 - Proj >= 4.4.x - GEOS >= 3.0 - Sqlite3 >= 3.0.0 - GDAL/OGR >= 1.4.x - Qwt >= 5.0 Optional dependencies: - for GRASS plugin - GRASS >= 6.0.0 (libraries compiled with exceptions support on Linux 32bit) - for georeferencer - GSL >= 1.8 - for postgis support and SPIT plugin - PostgreSQL >= 8.0.x - for gps plugin - expat >= 1.95 and gpsbabel - for mapserver export and PyQGIS - Python >= 2.3 (2.5+ preferred) - for python support - SIP >= 4.8, PyQt >= must match Qt version - for qgis mapserver - FastCGI 3. Building on GNU/Linux ======================== 3.1. Building QGIS with Qt 4.x ============================== Requires: Ubuntu / Debian derived distro These notes are for Ubuntu - other versions and Debian derived distros may require slight variations in package names. These notes are for if you want to build QGIS from source. One of the major aims here is to show how this can be done using binary packages for *all* dependencies - building only the core QGIS stuff from source. I prefer this approach because it means we can leave the business of managing system packages to apt and only concern ourselves with coding QGIS! This document assumes you have made a fresh install and have a 'clean' system. These instructions should work fine if this is a system that has already been in use for a while, you may need to just skip those steps which are irrelevant to you. /!\ Note: Refer to the section Building Debian packages for building debian packages. Unless you plan to develop on QGIS, that is probably the easiest option to compile and install QGIS. 3.2. Prepare apt ================ The packages qgis depends on to build are available in the "universe" component of Ubuntu. This is not activated by default, so you need to activate it: 1. Edit your /etc/apt/sources.list file. 2. Uncomment the all the lines starting with "deb" Also you will need to be running (K)Ubuntu 'edgy' or higher in order for all dependencies to be met. Now update your local sources database: sudo apt-get update 3.3. Install build dependencies =============================== || Distribution | install command for packages | | lenny | ``apt-get install bison cmake doxygen flex graphviz grass-dev libexpat1-dev libfcgi-dev libgdal1-dev libgeos-dev libgsl0-dev libpq-dev libqt4-dev libqwt5-qt4-dev libsqlite3-dev pkg-config proj pyqt4-dev-tools python python-dev python-qt4 python-qt4-dev python-sip4-dev sip4 txt2tags`` | | lucid | ``apt-get install bison cmake doxygen flex graphviz grass-dev libexpat1-dev libfcgi-dev libgdal1-dev libgeos-dev libgsl0-dev libpq-dev libproj-dev libqt4-dev libqwt5-qt4-dev libspatialite-dev libsqlite3-dev pkg-config pyqt4-dev-tools python python-dev python-qt4 python-qt4-dev python-sip python-sip-dev txt2tags`` | | maverick | ``apt-get install bison cmake doxygen flex graphviz grass-dev libexpat1-dev libfcgi-dev libgdal1-dev libgeos-dev libgsl0-dev libpq-dev libproj-dev libqt4-dev libqtwebkit-dev libqwt5-qt4-dev libspatialite-dev libsqlite3-dev pkg-config pyqt4-dev-tools python python-dev python-qt4 python-qt4-dev python-sip python-sip-dev txt2tags`` | | natty | ``apt-get install bison cmake doxygen flex graphviz grass-dev libexpat1-dev libfcgi-dev libgdal1-dev libgeos-dev libgsl0-dev libpq-dev libproj-dev libqt4-dev libqtwebkit-dev libqwt5-qt4-dev libspatialite-dev libsqlite3-dev pkg-config pyqt4-dev-tools python python-dev python-qt4 python-qt4-dev python-sip python-sip-dev txt2tags`` | | sid | ``apt-get install bison cmake doxygen flex graphviz grass-dev libexpat1-dev libfcgi-dev libgdal1-dev libgeos-dev libgsl0-dev libpq-dev libproj-dev libqt4-dev libqtwebkit-dev libqwt5-qt4-dev libspatialite-dev libsqlite3-dev pkg-config pyqt4-dev-tools python python-dev python-qt4 python-qt4-dev python-sip python-sip-dev txt2tags`` | | squeeze | ``apt-get install bison cmake doxygen flex graphviz grass-dev libexpat1-dev libfcgi-dev libgdal1-dev libgeos-dev libgsl0-dev libpq-dev libproj-dev libqt4-dev libqwt5-qt4-dev libspatialite-dev libsqlite3-dev pkg-config pyqt4-dev-tools python python-dev python-qt4 python-qt4-dev python-sip python-sip-dev txt2tags`` | (extracted from the respective control files in debian/) /!\ A Special Note: If you are following this set of instructions on a system where you already have Qt3 development tools installed, there will be a conflict between Qt3 tools and Qt4 tools. For example, qmake will point to the Qt3 version not the Qt4. Ubuntu Qt4 and Qt3 packages are designed to live alongside each other. This means that for example if you have them both installed you will have three qmake exe's: /usr/bin/qmake -> /etc/alternatives/qmake /usr/bin/qmake-qt3 /usr/bin/qmake-qt4 The same applies to all other Qt binaries. You will notice above that the canonical 'qmake' is managed by apt alternatives, so before we start to build QGIS, we need to make Qt4 the default. To return Qt3 to default later you can use this same process. You can use apt alternatives to correct this so that the Qt4 version of applications is used in all cases: sudo update-alternatives --config qmake sudo update-alternatives --config uic sudo update-alternatives --config designer sudo update-alternatives --config assistant sudo update-alternatives --config qtconfig sudo update-alternatives --config moc sudo update-alternatives --config lupdate sudo update-alternatives --config lrelease sudo update-alternatives --config linguist Use the simple command line dialog that appears after running each of the above commands to select the Qt4 version of the relevant applications. /!\ Note: For python language bindings SIP >= 4.5 and PyQt4 >= 4.1 is required! Some stable GNU/Linux distributions (e.g. Debian or SuSE) only provide SIP < 4.5 and PyQt4 < 4.1. To include support for python language bindings you may need to build and install those packages from source. 3.4. Setup ccache (Optional) ============================ You should also setup ccache to speed up compile times: cd /usr/local/bin sudo ln -s /usr/bin/ccache gcc sudo ln -s /usr/bin/ccache g++ 3.5. Prepare your development environment ========================================= As a convention I do all my development work in $HOME/dev/, so in this case we will create a work environment for C++ development work like this: mkdir -p ${HOME}/dev/cpp cd ${HOME}/dev/cpp This directory path will be assumed for all instructions that follow. 3.6. Check out the QGIS Source Code =================================== There are two ways the source can be checked out. Use the anonymous method if you do not have edit privaleges for the QGIS source repository, or use the developer checkout if you have permissions to commit source code changes. 1. Anonymous Checkout cd ${HOME}/dev/cpp svn co https://svn.osgeo.org/qgis/trunk/qgis qgis 2. Developer Checkout cd ${HOME}/dev/cpp svn co --username https://svn.osgeo.org/qgis/trunk/qgis qgis The first time you check out the source you will be prompted to accept the qgis.org certificate. Press 'p' to accept it permanently: Error validating server certificate for 'https://svn.qgis.org:443': - The certificate is not issued by a trusted authority. Use the fingerprint to validate the certificate manually! Certificate information: - Hostname: svn.qgis.org - Valid: from Apr 1 00:30:47 2006 GMT until Mar 21 00:30:47 2008 GMT - Issuer: Developer Team, Quantum GIS, Anchorage, Alaska, US - Fingerprint: 2f:cd:f1:5a:c7:64:da:2b:d1:34:a5:20:c6:15:67:28:33:ea:7a:9b (R)eject, accept (t)emporarily or accept (p)ermanently? 3.7. Starting the compile ========================= I compile my development version of QGIS into my ~/apps directory to avoid conflicts with Ubuntu packages that may be under /usr. This way for example you can use the binary packages of QGIS on your system along side with your development version. I suggest you do something similar: mkdir -p ${HOME}/apps Now we create a build directory and run ccmake: cd qgis mkdir build cd build ccmake .. When you run ccmake (note the .. is required!), a menu will appear where you can configure various aspects of the build. If you do not have root access or do not want to overwrite existing QGIS installs (by your packagemanager for example), set the CMAKE_BUILD_PREFIX to somewhere you have write access to (I usually use /home/timlinux/apps). Now press 'c' to configure, 'e' to dismiss any error messages that may appear. and 'g' to generate the make files. Note that sometimes 'c' needs to be pressed several times before the 'g' option becomes available. After the 'g' generation is complete, press 'q' to exit the ccmake interactive dialog. Now on with the build: make make install It may take a little while to build depending on your platform. After that you can try to run QGIS: $HOME/apps/bin/qgis If all has worked properly the QGIS application should start up and appear on your screen. 3.8. Building Debian packages ============================= Instead of creating a personal installation as in the previous step you can also create debian package. This is done from the qgis root directory, where you'll find a debian directory. First you need to install the debian packaging tools once: apt-get install build-essential First you need to create an changelog entry for your distribution. For example for Ubuntu Lucid: dch -l ~lucid --force-distribution --distribution lucid "lucid build" The QGIS packages will be created with: dpkg-buildpackage -us -uc -b /!\ Note: If dpkg-buildpackage complains about unmet build dependencies you can install them using apt-get and re-run the command. /!\ Note: If you have libqgis1-dev installed, you need to remove it first using dpkg -r libqgis1-dev. Otherwise dpkg-buildpackage will complain about a build conflict. The packages are created in the parent directory (ie. one level up). Install them using dpkg. E.g.: sudo debi 3.9. A practical case: Building QGIS and GRASS from source on Ubuntu with ECW and MrSID formats support ======================================================================================================= The following procedure has been tested on Ubuntu 8.04, 8.10 and 9.04 32bit. If you want to use different versions of the software (gdal, grass, qgis), just make the necessary adjustments to the following code. This guide assumes that you don't have installed any previous version of gdal, grass and qgis. 3.9.1. Step 1: install base packages ==================================== First you need to install the necessary packages required to download the source code and compile it. Open the terminal and issue the following command: sudo apt-get install build-essential g++ subversion 3.9.2. Step 2: compile and install the ecw libraries ==================================================== Go to the ERDAS web site http://www.erdas.com/ and follow the links "'products --> ECW JPEG2000 Codec SDK --> downloads'" then download the "'Image Compression SDK Source Code 3.3'" (you'll need to make a registration and accept a license). Uncompress the arquive in a proper location (this guide assumes that all the downloaded source code will be placed in the user home) and the enter the newly created folder cd /libecwj2-3.3 Compile the code with the standard commands ./configure then make then sudo make install leave the folder cd .. 3.9.3. Step 3: download the MrSID binaries ========================================== Go to the LIZARDTECH web site http://www.lizardtech.com/ and follow the links "'download --> Developer SDKs'", then download the "'GeoExpress SDK for Linux (x86) - gcc 4.1 32-bit'" (you'll need to make a registration and accept a license). Uncompress the downloaded file. The resulting directory name should be similar to "Geo_DSDK-7.0.0.2167" 3.9.4. Step 4: compile and install the gdal libraries ===================================================== Download the latest gdal source code svn checkout https://svn.osgeo.org/gdal/trunk/gdal gdal then copy a few files from the MrSID binaries folder to the folder with the gdal source code ('replace "USERNAME" with your actual account username') cp /home/USERNAME/Geo_DSDK-7.0.0.2167/include/*.* /home/USERNAME/gdal/frmts/mrsid/ enter the gdal source code folder cd /gdal and run configure with a few specific parameters ./configure --without-grass --with-mrsid=../Geo_DSDK-7.0.0.2167 --without-jp2mrsid at the end of the configuration process you should read something like ... GRASS support: no ... ... ... ECW support: yes MrSID support yes ... then compile normally make and sudo make install finish the process by creating the necessary links to the most recent shared libraries sudo ldconfig at this point you may want to check if gdal was compiled correctly with MrSID and ECW support by issuing one (or both) of the following commands gdalinfo --formats | grep 'ECW' gdalinfo --formats | grep 'SID' leave the folder cd .. 3.9.5. Step 5: compile and install GRASS ======================================== Before downloading and compile GRASS source code you need to install a few other libraries and programs. We can do this trough apt sudo apt-get install flex bison libreadline5-dev libncurses5-dev lesstif2-dev debhelper dpatch libtiff4-dev \ tcl8.4-dev tk8.4-dev fftw-dev xlibmesa-gl-dev libfreetype6-dev autoconf2.13 autotools-dev \ libgdal1-dev proj libjpeg62-dev libpng12-dev libpq-dev unixodbc-dev doxygen fakeroot cmake \ python-dev python-qt4-common python-qt4-dev python-sip4 python2.5-dev sip4 libglew1.5-dev libxmu6 \ libqt4-dev libgsl0-dev python-qt4 swig python-wxversion python-wxgtk2.8 libwxgtk2.8-0 libwxbase2.8-0 tcl8.4-dev \ tk8.4-dev tk8.4 libfftw3-dev libfftw3-3 At this point we can get the GRASS source code: you may want to download it trough svn or maybe you want just to download the latest available source code arquive. For example the GRASS 6.4rc4 is available at http://grass.itc.it/grass64/source/grass-6.4.0RC4.tar.gz Uncompress the arquive, enter the newly created folder and run configure with a few specific parameters CFLAGS="-fexceptions" ./configure --with-tcltk-includes=/usr/include/tcl8.4 --with-proj-share=/usr/share/proj --with-gdal=/usr/local/bin/gdal-config \ --with-python=/usr/bin/python2.5-config The additional gcc option -fexceptions is necessary to enable exceptions support in GRASS libraries. It is currently the only way to avoid QGIS crashes if a fatal error happens in GRASS library. See also http://trac.osgeo.org/grass/ticket/869 Then as usual (it will take a while) make and sudo make install leave the folder cd .. you have now compiled and installed GRASS (also with the new wxpyhton interface) so you may want to give it a try grass64 -wxpython 3.9.6. Step 6: compile and install QGIS ======================================= As for GRASS you can obtain the QGIS source code from different sources, for instance from svn or just by downloading one of the source code arquives available at http://www.qgis.org/download/sources.html For example download the QGIS 1.1.0 source code here http://download.osgeo.org/qgis/src/qgis_1.1.0.tar.gz uncompress the arquive and enter the newly created folder cd /qgis_1.1.0 then run ccmake ccmake . press the "c" key, then when the option list will appear we need to manually configure the "GRASS_PREFIX" parameter. Scroll down until the "GRASS_PREFIX" will appear, press enter and manually set it to /usr/local/grass-6.4.0RC4 then press enter again. Press the "c" again and the option "Press [g] to generate and exit" will appear. Press the "g" key to generate and exit. then as usual (it will take a while) make and sudo make install At the end of the process you should have QGIS and GRASS working with MrSID and ECW raster format support. To run QGIS just use this command qgis 4. Building on Windows ====================== 4.1. Building with Microsoft Visual Studio ========================================== This section describes how to build QGIS using Visual Studio on Windows. This is currently also who the binary QGIS packages are made (earlier versions used MinGW). This section describes the setup required to allow Visual Studio to be used to build QGIS. 4.1.1. Visual C++ Express Edition ================================= The free (as in free beer) Express Edition installer is available under: http://download.microsoft.com/download/d/c/3/dc3439e7-5533-4f4c-9ba0-8577685b6e7e/vcsetup.exe The optional products are not necessary. In the process the Windows SDKs for Visual Studio 2008 will also be downloaded and installed. You also need the Microsoft Windows Server® 2003 R2 Platform SDK (for setupapi): http://download.microsoft.com/download/f/a/d/fad9efde-8627-4e7a-8812-c351ba099151/PSDK-x86.exe You only need Microsoft Windows Core SDK / Build Environment (x86 32-Bit). 4.1.2. Other tools and dependencies =================================== Download and install following packages: || Tool | Website | | CMake | http://www.cmake.org/files/v2.8/cmake-2.8.4-win32-x86.exe | | Flex | http://gnuwin32.sourceforge.net/downlinks/flex.php | | Bison | http://gnuwin32.sourceforge.net/downlinks/bison.php | | SVN | http://sourceforge.net/projects/win32svn/files/1.6.13/Setup-Subversion-1.6.13.msi/download | | or GIT | http://msysgit.googlecode.com/files/Git-1.7.4-preview20110204.exe | | OSGeo4W | http://download.osgeo.org/osgeo4w/osgeo4w-setup.exe | OSGeo4W does not only provide ready packages for the current QGIS release and nightly builds of the trunk, but also offers most of the dependencies needs to build it. For the QGIS build you need to install following packages from OSGeo4W (select Advanced Installation): - expat - fcgi - gdal17 - grass - gsl-devel - iconv - pyqt4 - qt4-devel - qwt5-devel-qt4 - sip This will also select packages the above packages depend on. Additionally QGIS also needs the include file unistd.h, which normally doesn't exist on Windows. It's shipped with Flex/Bison in GnuWin32\include and needs to be copied into the VC\include directory of your Visual C++ installation. Earlier versions of this document also covered how to build all above dependencies. If you're interested in that, check the history of this page in the Wiki or the SVN repository. 4.1.3. Setting up the Visual Studio project with CMake ====================================================== To start a command prompt with an environment that both has the VC++ and the OSGeo4W variables create the following batch file (assuming the above packages were installed in the default locations): @echo off path %SYSTEMROOT%\system32;%SYSTEMROOT%;%SYSTEMROOT%\System32\Wbem;%PROGRAMFILES%\CMake 2.8\bin;%PROGRAMFILES%\subversion\bin;%PROGRAMFILES%\GnuWin32\bin set PYTHONPATH= set VS90COMNTOOLS=%PROGRAMFILES%\Microsoft Visual Studio 9.0\Common7\Tools\ call "%PROGRAMFILES%\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86 set INCLUDE=%INCLUDE%;%PROGRAMFILES%\Microsoft Platform SDK for Windows Server 2003 R2\include set LIB=%LIB%;%PROGRAMFILES%\Microsoft Platform SDK for Windows Server 2003 R2\lib set OSGEO4W_ROOT=C:\OSGeo4W call "%OSGEO4W_ROOT%\bin\o4w_env.bat" @set GRASS_PREFIX=c:/OSGeo4W/apps/grass/grass-6.4.0 @set INCLUDE=%INCLUDE%;%OSGEO4W_ROOT%\apps\gdal-17\include;%OSGEO4W_ROOT%\include @set LIB=%LIB%;%OSGEO4W_ROOT%\apps\gdal-17\lib;%OSGEO4W_ROOT%\lib @cmd Start the batch file and on the command prompt checkout the QGIS source from svn to the source directory qgis-trunk: svn co https://svn.osgeo.org/qgis/trunk/qgis qgis-trunk or using git-svn (from the git shell): git svn clone --username $USER --revision 15611:HEAD https://svn.osgeo.org/qgis/trunk/qgis Create a 'build' directory somewhere. This will be where all the build output will be generated. Now run cmake-gui and in the Where is the source code: box, browse to the top level QGIS directory. In the Where to build the binaries: box, browse to the 'build' directory you created. Adjust the path to bison and flex so that the shortened C:/Progra~1 is used rather than C:/Program Files. Verify that the 'BINDINGS_GLOBAL_INSTALL' option is not checked, so that python bindings are placed into the output directory when you run the INSTALL target. Hit Configure to start the configuration and select Visual Studio 9 2008 and keep native compilers and click Finish. The configuration should complete without any further questions and allow you to click Generate. Now close cmake-gui and continue on the command prompt by starting vcexpress. Use File / Open / Project/Solutions and open the qgis-x.y.z.sln File in your project directory. Change Solution Configuration from Debug to RelWithDebInfo (Release with Debug Info) or Release before you build QGIS using the ALL_BUILD target (otherwise you need debug libraries that are not included). After the build completed you should install QGIS using the INSTALL target. Install QGIS by building the INSTALL project. By default this will install to c:\Program Files\qgis (this can be changed by changing the CMAKE_INSTALL_PREFIX variable in cmake-gui). You will also either need to add all the dependency DLLs to the QGIS install directory or add their respective directories to your PATH. 4.1.4. Packaging ================ To create a windows 'all in one' standalone package under ubuntu (yes you read correctly) do the following: sudo apt-get install nsis Now cd qgis/ms-windows/osgeo4w And run the nsis creation script: creatensis.pl When the script completes, it should have created a QGIS installer executable in the ms-windows directory (using the QGIS binaries from OSGEO4W). 4.1.5. Packaging your own build of QGIS ======================================= Assuming you have completed the above packaging step, if you want to include your own hand built QGIS executables, you need to copy them in from your windows installation into the ms-windows file tree created by the creatensis script. cd ms-windows/ rm -rf osgeo4w/unpacked/apps/qgis/* cp -r /tmp/qgis1.7.0/* osgeo4w/unpacked/apps/qgis/ Now create a package. ./quickpackage.sh After this you should now have a nsis installer containing your own build of QGIS and all dependencies needed to run it on a windows machine. 4.1.6. Osgeo4w packaging ======================== The actual packaging process is currently not documented, for now please take a look at: ms-windows/osgeo4w/package.cmd 4.2. Building using MinGW ========================= Note: This section might be outdated as nowadays Visual C++ is use to build the "official" packages. Note: For a detailed account of building all the dependencies yourself you can visit Marco Pasetti's website here: http://www.webalice.it/marco.pasetti/qgis+grass/BuildFromSource.html Read on to use the simplified approach with pre-built libraries... 4.2.1. MSYS =========== MSYS provides a unix style build environment under windows. We have created a zip archive that contains just about all dependencies. Get this: http://download.osgeo.org/qgis/win32/msys.zip and unpack to c:\msys If you wish to prepare your msys environment yourself rather than using our pre-made one, detailed instructions are provided elsewhere in this document. 4.2.2. Qt ========= Download Qt opensource precompiled edition exe and install (including the download and install of mingw) from here: http://qt.nokia.com/downloads/ When the installer will ask for MinGW, you don't need to download and install it, just point the installer to c:\msys\mingw When Qt installation is complete: Edit C:\Qt\4.7.0\bin\qtvars.bat and add the following lines: set PATH=%PATH%;C:\msys\local\bin;c:\msys\local\lib set PATH=%PATH%;"C:\Program Files\Subversion\bin" I suggest you also add C:\Qt\4.7.0\bin\ to your Environment Variables Path in the windows system preferences. If you plan to do some debugging, you'll need to compile debug version of Qt: C:\Qt\4.7.0\bin\qtvars.bat compile_debug Note: there is a problem when compiling debug version of Qt 4.7, the script ends with this message "mingw32-make: *** No rule to make target `debug'. Stop.". To compile the debug version you have to go out of src directory and execute the following command: c:\Qt\4.7.0 make 4.2.3. Flex and Bison ===================== Get Flex http://sourceforge.net/project/showfiles.php?group_id=23617&package_id=16424 (the zip bin) and extract it into c:\msys\mingw\bin 4.2.4. Python stuff (optional) ============================== Follow this section in case you would like to use Python bindings for QGIS. To be able to compile bindings, you need to compile SIP and PyQt4 from sources as their installer doesn't include some development files which are necessary. 4.2.4.1. Download and install Python - use Windows installer ============================================================ (It doesn't matter to what folder you'll install it) http://python.org/download/ 4.2.4.2. Download SIP and PyQt4 sources ======================================= http://www.riverbankcomputing.com/software/sip/download http://www.riverbankcomputing.com/software/pyqt/download Extract each of the above zip files in a temporary directory. Make sure to get versions that match your current Qt installed version. 4.2.4.3. Compile SIP ==================== c:\Qt\4.7.0\bin\qtvars.bat python configure.py -p win32-g++ make make install 4.2.4.4. Compile PyQt ===================== c:\Qt\4.7.0\bin\qtvars.bat python configure.py make make install 4.2.4.5. Final python notes =========================== /!\ You can delete the directories with unpacked SIP and PyQt4 sources after a successfull install, they're not needed anymore. 4.2.5. Subversion ================= In order to check out QGIS sources from the repository, you need Subversion client. This installer should work fine: http://www.sliksvn.com/pub/Slik-Subversion-1.6.13-win32.msi 4.2.6. CMake ============ CMake is build system used by Quantum GIS. Download it from here: http://www.cmake.org/files/v2.8/cmake-2.8.2-win32-x86.exe 4.2.7. QGIS =========== Start a cmd.exe window ( Start -> Run -> cmd.exe ) Create development directory and move into it md c:\dev\cpp cd c:\dev\cpp Check out sources from SVN: For svn trunk: svn co https://svn.osgeo.org/qgis/trunk/qgis For svn 1.5 branch svn co https://svn.osgeo.org/qgis/branches/Release-1_5_0 qgis1.5.0 4.2.8. Compiling ================ As a background read the generic building with CMake notes at the end of this document. Start a cmd.exe window ( Start -> Run -> cmd.exe ) if you don't have one already. Add paths to compiler and our MSYS environment: c:\Qt\4.7.0\bin\qtvars.bat For ease of use add c:\Qt\4.7.0\bin\ to your system path in system properties so you can just type qtvars.bat when you open the cmd console. Create build directory and set it as current directory: cd c:\dev\cpp\qgis md build cd build 4.2.9. Configuration ==================== cmakesetup .. Note: You must include the '..' above. Click 'Configure' button. When asked, you should choose 'MinGW Makefiles' as generator. There's a problem with MinGW Makefiles on Win2K. If you're compiling on this platform, use 'MSYS Makefiles' generator instead. All dependencies should be picked up automatically, if you have set up the Paths correctly. The only thing you need to change is the installation destination (CMAKE_INSTALL_PREFIX) and/or set 'Debug'. For compatibility with NSIS packaging scripts I recommend to leave the install prefix to its default c:\program files\ When configuration is done, click 'OK' to exit the setup utility. 4.2.10. Compilation and installation ==================================== make make install 4.2.11. Run qgis.exe from the directory where it's installed (CMAKE_INSTALL_PREFIX) =================================================================================== Make sure to copy all .dll:s needed to the same directory as the qgis.exe binary is installed to, if not already done so, otherwise QGIS will complain about missing libraries when started. A possibility is to run qgis.exe when your path contains c:\msys\local\bin and c:\msys\local\lib directories, so the DLLs will be used from that place. 4.2.12. Create the installation package: (optional) =================================================== Download and install NSIS from (http://nsis.sourceforge.net/Main_Page) Now using windows explorer, enter the win_build directory in your QGIS source tree. Read the READMEfile there and follow the instructions. Next right click on qgis.nsi and choose the option 'Compile NSIS Script'. 4.3. Creation of MSYS environment for compilation of Quantum GIS ================================================================ 4.3.1. Initial setup ==================== 4.3.1.1. MSYS ============= This is the environment that supplies many utilities from UNIX world in Windows and is needed by many dependencies to be able to compile. Download from here: http://puzzle.dl.sourceforge.net/sourceforge/mingw/MSYS-1.0.11-2004.04.30-1.exe Install to c:\msys All stuff we're going to compile is going to get to this directory (resp. its subdirs). 4.3.1.2. MinGW ============== Download from here: http://puzzle.dl.sourceforge.net/sourceforge/mingw/MinGW-5.1.3.exe Install to c:\msys\mingw It suffices to download and install only g++ and mingw-make components. 4.3.1.3. Flex and Bison ======================= Flex and Bison are tools for generation of parsers, they're needed for GRASS and also QGIS compilation. Download the following packages: http://gnuwin32.sourceforge.net/downlinks/flex-bin-zip.php http://gnuwin32.sourceforge.net/downlinks/bison-bin-zip.php http://gnuwin32.sourceforge.net/downlinks/bison-dep-zip.php Unpack them all to c:\msys\local 4.3.2. Installing dependencies ============================== 4.3.2.1. Getting ready ====================== Paul Kelly did a great job and prepared a package of precompiled libraries for GRASS. The package currently includes: - zlib-1.2.3 - libpng-1.2.16-noconfig - xdr-4.0-mingw2 - freetype-2.3.4 - fftw-2.1.5 - PDCurses-3.1 - proj-4.5.0 - gdal-1.4.1 It's available for download here: http://www.stjohnspoint.co.uk/grass/wingrass-extralibs.tar.gz Moreover he also left the notes how to compile it (for those interested): http://www.stjohnspoint.co.uk/grass/README.extralibs Unpack the whole package to c:\msys\local 4.3.2.2. GRASS ============== Grab sources from CVS or use a weekly snapshot, see: http://grass.itc.it/devel/cvs.php In MSYS console go to the directory where you've unpacked or checked out sources (e.g. c:\msys\local\src\grass-6.3.cvs) Run these commands: export PATH="/usr/local/bin:/usr/local/lib:$PATH" ./configure --prefix=/usr/local --bindir=/usr/local --with-includes=/usr/local/include --with-libs=/usr/local/lib --with-cxx --without-jpeg \ --without-tiff --with-postgres=yes --with-postgres-includes=/local/pgsql/include --with-pgsql-libs=/local/pgsql/lib --with-opengl=windows --with-fftw \ --with-freetype --with-freetype-includes=/mingw/include/freetype2 --without-x --without-tcltk --enable-x11=no --enable-shared=yes \ --with-proj-share=/usr/local/share/proj make make install It should get installed to c:\msys\local\grass-6.3.cvs By the way, these pages might be useful: - http://grass.gdf-hannover.de/wiki/WinGRASS_Current_Status - http://geni.ath.cx/grass.html 4.3.2.3. GEOS ============= Download the sources: http://geos.refractions.net/geos-2.2.3.tar.bz2 Unpack to e.g. c:\msys\local\src To compile, I had to patch the sources: in file source/headers/timeval.h line 13. Change it from: #ifdef _WIN32 to: #if defined(_WIN32) && defined(_MSC_VER) Now, in MSYS console, go to the source directory and run: ./configure --prefix=/usr/local make make install 4.3.2.4. SQLITE =============== You can use precompiled DLL, no need to compile from source: Download this archive: http://www.sqlite.org/sqlitedll-3_3_17.zip and copy sqlite3.dll from it to c:\msys\local\lib Then download this archive: http://www.sqlite.org/sqlite-source-3_3_17.zip and copy sqlite3.h to c:\msys\local\include 4.3.2.5. GSL ============ Download sources: ftp://ftp.gnu.org/gnu/gsl/gsl-1.9.tar.gz Unpack to c:\msys\local\src Run from MSYS console in the source directory: ./configure make make install 4.3.2.6. EXPAT ============== Download sources: http://dfn.dl.sourceforge.net/sourceforge/expat/expat-2.0.0.tar.gz Unpack to c:\msys\local\src Run from MSYS console in the source directory: ./configure make make install 4.3.2.7. POSTGRES ================= We're going to use precompiled binaries. Use the link below for download: http://wwwmaster.postgresql.org/download/mirrors-ftp?file=%2Fbinary%2Fv8.2.4%2Fwin32%2Fpostgresql-8.2.4-1-binaries-no-installer.zip copy contents of pgsql directory from the archive to c:\msys\local 4.3.3. Cleanup ============== We're done with preparation of MSYS environment. Now you can delete all stuff in c:\msys\local\src - it takes quite a lot of space and it's not necessary at all. 5. MacOS X: building using frameworks and Cmake =============================================== In this approach I will try to avoid as much as possible building dependencies from source and rather use frameworks wherever possible. The base system here is Mac OS X 10.4 (Tiger), with a single architecture build. Included are a few notes for building on Mac OS X 10.5 (Leopard) and 10.6 (Snow Leopard). Make sure to read each section completely before typing the first command you see. General note on Terminal usage: When I say "cd" to a folder in a Terminal, it means type "cd " (without the quotes, make sure to type a space after) and then type the path to said folder, then . A simple way to do this without having to know and type the full path is, after type the "cd " part, drag the folder (use the icon in its window title bar, or drag a folder from within a window) from the Desktop to the Terminal, then tap . Parallel Compilation: On multiprocessor/multicore Macs, it's possible to speed up compilation, but it's not automatic. Whenever you type "make" (but NOT "make install"), instead type: make -j [n] Replace [n] with the number of cores and/or processors your Mac has. On recent models with hyperthreading processors this can be double the physical count of processors and cores. ie: Mac Pro "8 Core" model (2 quad core processors) = 8 ie: Macbook Pro i5 (hyperthreading) = 2 cores X 2 = 4 5.1. Install Qt4 from .dmg ========================== You need a minimum of Qt-4.4.0. I suggest getting the latest. Snow Leopard note: If you are building on Snow Leopard, you will need to decide between 32-bit support in the older, Qt Carbon branch, or 64-bit support in the Qt Cocoa branch. Appropriate installers are available for both as of Qt-4.5.2. Qt 4.6+ is recommended for Cocoa. PPC note: There appear to be issues with Qt Cocoa on PPC Macs. QT Carbon is recommended on PPC Macs. http://qt.nokia.com/downloads If you want debug frameworks, Qt also provides a dmg with these. These are in addition to the non-debug frameworks. Once downloaded open the dmg and run the installer. Note you need admin privileges to install. Qt note: Starting in Qt 4.4, libQtCLucene was added, and in 4.5 libQtUiTools was added, both in /usr/lib. When using a system SDK these libraries will not be found. To fix this problem, add symlinks to /usr/local: sudo ln -s /usr/lib/libQtUiTools.a /usr/local/lib/ sudo ln -s /usr/lib/libQtCLucene.dylib /usr/local/lib/ These should then be found automatically on Leopard and above. Earlier systems may need some help by adding '-L/usr/local/lib' to CMAKE_SHARED_LINKER_FLAGS, CMAKE_MODULE_LINKER_FLAGS and CMAKE_EXE_LINKER_FLAGS in the cmake build. 5.2. Install development frameworks for QGIS dependencies ========================================================= Download William Kyngesburye's excellent GDAL Complete package that includes PROJ, GEOS, GDAL, SQLite3, and image libraries, as frameworks. There is also a GSL framework. http://www.kyngchaos.com/wiki/software/frameworks Once downloaded, open and install the frameworks. William provides an additional installer package for Postgresql (for PostGIS support). Qgis just needs the libpq client library, so unless you want to setup the full Postgres + PostGIS server, all you need is the client-only package. It's available here: http://www.kyngchaos.com/wiki/software/postgres Also available is a GRASS application: http://www.kyngchaos.com/wiki/software/grass 5.2.1. Additional Dependencies: General compatibility note ========================================================== There are some additional dependencies that, at the time of writing, are not provided as frameworks or installers so we will need to build these from source. If you are wanting to build Qgis as a 64-bit application, you will need to provide the appropriate build commands to produce 64-bit support in dependencies. Likewise, for 32-bit support on Snow Leopard, you will need to override the default system architecture, which is 64-bit, according to instructions for individual dependency packages. Stable release versions are preferred. Beta and other development versions may have problems and you are on your own with those. 5.2.2. Additional Dependencies: Expat ===================================== Snow Leopard note: Snow Leopard includes a usable expat, so this step is not necessary on Snow Leopard. Get the expat sources: http://sourceforge.net/project/showfiles.php?group_id=10127 Double-click the source tarball to unpack, then, in Terminal.app, cd to the source folder and: ./configure make sudo make install 5.2.3. Additional Dependencies: Python ====================================== Leopard and Snow Leopard note: Leopard and Snow Leopard include a usable Python 2.5 and 2.6, respectively. So there is no need to install Python on Leopard and Snow Leopard. You can still install Python from python.org if preferred. If installing from python.org, make sure you install at least the latest Python 2.x from http://www.python.org/download/ Python 3 is a major change, and may have compatibility issues, so try it at your own risk. 5.2.4. Additional Dependencies: SIP =================================== Retrieve the python bindings toolkit SIP from http://www.riverbankcomputing.com/software/sip/download Double-click the source tarball to unpack it, then, in Terminal.app, cd to the source folder and (this installs by default into the Python framework, and is appropriate only for python.org Python installs): python configure.py make sudo make install Leopard notes If building on Leopard, using Leopard's bundled Python, SIP wants to install in the system path -- this is not a good idea. Use this configure command instead of the basic configure above: python configure.py -n -d /Library/Python/2.5/site-packages -b /usr/local/bin \ -e /usr/local/include -v /usr/local/share/sip -s MacOSX10.5.sdk Snow Leopard notes Similar to Leopard, you should install outside the system Python path. Also, you need to specify the architecture you want (requires at least SIP 4.9), and make sure to run the versioned python binary (this one responds to the 'arch' command, 'python' does not). If you are using 32-bit Qt (Qt Carbon): python2.6 configure.py -n -d /Library/Python/2.6/site-packages -b /usr/local/bin \ -e /usr/local/include -v /usr/local/share/sip --arch=i386 -s MacOSX10.6.sdk For 64-bit Qt (Qt Cocoa), use this configure line: python2.6 configure.py -n -d /Library/Python/2.6/site-packages -b /usr/local/bin \ -e /usr/local/include -v /usr/local/share/sip --arch=x86_64 -s MacOSX10.6.sdk 5.2.5. Additional Dependencies: PyQt ==================================== Retrieve the python bindings toolkit for Qt from http://www.riverbankcomputing.com/software/pyqt/download Double-click the source tarball to unpack it, then, in Terminal.app, cd to the source folder and (this installs by default into the Python framework, and is appropriate only for python.org Python installs): python configure.py yes There is a problem with the configuration that needs to be fixed now (it affects PyQwt compilation later). Edit pyqtconfig.py and change the qt_dir line to: 'qt_dir': '/usr', Then continue with compilation and installation (this is a good place to use parallel compilation, if you can): make sudo make install Leopard notes If building on Leopard, using Leopard's bundled Python, PyQt wants to install in the system path -- this is not a good idea. Use this configure command instead of the basic configure above: python configure.py -d /Library/Python/2.5/site-packages -b /usr/local/bin If there is a problem with undefined symbols in QtOpenGL on Leopard, edit QtOpenGL/makefile and add -undefined dynamic_lookup to LFLAGS. Then make again. Snow Leopard notes Similar to Leopard, you should install outside the system Python path. Also, you need to specify the architecture you want (requires at least PyQt 4.6), and make sure to run the versioned python binary (this one responds to the 'arch' command, which is important for pyuic4, 'python' does not). If you are using 32-bit Qt (Qt Carbon): python2.6 configure.py -d /Library/Python/2.6/site-packages -b /usr/local/bin --use-arch i386 For 64-bit Qt (Qt Cocoa), use this configure line: python2.6 configure.py -d /Library/Python/2.6/site-packages -b /usr/local/bin --use-arch x86_64 5.2.6. Additional Dependencies: Qwt/PyQwt ========================================= The GPS tracking feature uses Qwt. Some popular 3rd-party plugins use PyQwt. You can take care of both with the PyQwt source from: http://pyqwt.sourceforge.net/ Double-click the tarball to unpack it. The following assumes PyQwt v5.2.0 (comes with Qwt 5.2.1). Normal compilation does both Qwt and PyQwt at the same time, but Qwt is statically linked into PyQwt, and Qgis can't use it. So, we need to split the build. First edit qwtconfig.pri in the qwt-5.2 subdir and change some settings so you don't get a bloated debug static library (too bad they are not configurable from qmake). Scroll down to the 'release/debug mode' block. Edit the last 'CONFIG +=' line, within an 'else' block, and change 'debug' to 'release'. Like so: else { CONFIG += release # release/debug } Also uncomment (remove # prefix) the line 'CONFIG += QwtDll'. Like so: CONFIG += QwtDll If you are building for Qt Carbon 32bit on Snow Leopard, add a line at the bottom: CONFIG += x86 Save and close. Now, cd into the qwt-5.2 subdir in a Terminal. Type these commands to build and install: qmake -spec macx-g++ make sudo make install sudo install_name_tool -id /usr/local/qwt-5.2.1-svn/lib/libqwt.5.dylib \ /usr/local/qwt-5.2.1-svn/lib/libqwt.5.dylib The Qwt shared library is now installed in /usr/local/qwt-5.x.x[-svn] (x.x is the minor.point version, and it may be an SVN version). Remember this for QGIS and PyQwt configuration. Now for PyQwt. Still in the Terminal: cd ../configure python configure.py --extra-include-dirs=/usr/local/qwt-5.2.1-svn/include \ --extra-lib-dirs=/usr/local/qwt-5.2.1-svn/lib --extra-libs=qwt make sudo make install Make sure to use the qwt install path from the Qwt build above. Snow Leopard note If using Qt Carbon, you need to specify which architectures to build, otherwise it will default to a combination that does not work (ie x86_64 for a Carbon Qt). This is not needed for Qt Cocoa. Configure as follows: python configure.py --extra-cflags="-arch i386" --extra-cxxflags="-arch i386" \ --extra-lflags="-arch i386" --extra-include-dirs=/usr/local/qwt-5.2.1-svn/include \ --extra-lib-dirs=/usr/local/qwt-5.2.1-svn/lib --extra-libs=qwt 5.2.7. Additional Dependencies: Bison ===================================== Leopard and Snow Leopard note: Leopard and Snow Leopard include Bison 2.3, so this step can be skipped on Leopard and Snow Leopard. The version of bison available by default on Mac OS X 10.4 is too old so you need to get a more recent one on your system. Download at least version 2.3 from: ftp.gnu.org/gnu/bison/ Now build and install it to a prefix of /usr/local.Ê Double-click the source tarball to unpack it, then cd to the source folder and: ./configure --prefix=/usr/local make sudo make install 5.3. Install CMake for OSX ========================== Get the latest source release from here: http://www.cmake.org/cmake/resources/software.html Binary installers are available for OS X, but they are not recommended (2.4 versions install in /usr instead of /usr/local, and 2.6 versions are a strange application). Instead, download the source, double-click the source tarball, then cd to the source folder and: ./bootstrap --docdir=/share/doc/CMake --mandir=/share/man make sudo make install 5.4. Install subversion for OSX =============================== Leopard and Snow Leopard note: Leopard and Snow Leopard (Xcode 3+) include SVN, so this step can be skipped on Leopard and Snow Leopard. The [http://sourceforge.net/projects/macsvn/MacSVN] project has a downloadable build of svn. If you are a GUI inclined person you may want to grab their gui client too. Get the command line client here: curl -O http://ufpr.dl.sourceforge.net/sourceforge/macsvn/Subversion_1.4.2.zip Once downloaded open the zip file and run the installer. You also need to install BerkleyDB available from the same http://sourceforge.net/projects/macsvn/ (website). At the time of writing the file was here: curl -O http://ufpr.dl.sourceforge.net/sourceforge/macsvn/Berkeley_DB_4.5.20.zip Once again unzip this and run the installer therein. Lastly we need to ensure that the svn commandline executeable is in the path. Add the following line to the end of /etc/bashrc using sudo: sudo vim /etc/bashrc And add this line to the bottom before saving and quiting: export PATH=/usr/local/bin:$PATH:/usr/local/pgsql/bin /usr/local/bin needs to be first in the path so that the newer bison (that will be built from source further down) is found before the bison (which is very old) that is installed by MacOSX Now close and reopen your shell to get the updated vars. 5.5. Check out QGIS from SVN ============================ Now we are going to check out the sources for QGIS. First we will create a directory for working in (or some folder of your choice): mkdir -p ~/dev/cpp cd ~/dev/cpp Now we check out the sources: Trunk: svn co https://svn.osgeo.org/qgis/trunk/qgis qgis For a release branch version x.y.z: svn co https://svn.qgis.org/qgis/branches/Release-x_y_z qgis-x.y.z The first time you check out QGIS sources you will probably get a message like this: Error validating server certificate for 'https://svn.qgis.org:443': - The certificate is not issued by a trusted authority. Use the fingerprint to validate the certificate manually! Certificate information: - Hostname: svn.qgis.org - Valid: from Apr 1 00:30:47 2006 GMT until Mar 21 00:30:47 2008 GMT - Issuer: Developer Team, Quantum GIS, Anchorage, Alaska, US - Fingerprint: 2f:cd:f1:5a:c7:64:da:2b:d1:34:a5:20:c6:15:67:28:33:ea:7a:9b (R)eject, accept (t)emporarily or accept (p)ermanently? I suggest you press 'p' to accept the key permanently. 5.6. Configure the build ======================== CMake supports out of source build so we will create a 'build' dir for the build process. OS X uses ${HOME}/Applications as a standard user app folder (it gives it the system app folder icon). If you have the correct permissions you may want to build straight into your /Applications folder. The instructions below assume you are building into a pre-existing ${HOME}/Applications directory. In a Terminal cd to the qgis source folder previously downloaded, then: mkdir build cd build cmake -D CMAKE_INSTALL_PREFIX=~/Applications -D CMAKE_BUILD_TYPE=Release \ -D CMAKE_BUILD_TYPE=MinSizeRel \ -D WITH_INTERNAL_SPATIALITE=FALSE -D WITH_MAPSERVER=TRUE \ -D QWT_LIBRARY=/usr/local/qwt-5.2.1-svn/lib/libqwt.dylib \ -D QWT_INCLUDE_DIR=/usr/local/qwt-5.2.1-svn/include \ .. This will automatically find and use the previously installed frameworks, and the GRASS application if installed. Or, to use a Unix-style build of GRASS, use the following cmake invocation (minimum GRASS version as stated in the Qgis requirements, substitute the GRASS path and version as required): cmake -D CMAKE_INSTALL_PREFIX=~/Applications -D CMAKE_BUILD_TYPE=Release \ -D CMAKE_BUILD_TYPE=MinSizeRel \ -D WITH_INTERNAL_SPATIALITE=FALSE -D WITH_MAPSERVER=TRUE \ -D QWT_LIBRARY=/usr/local/qwt-5.2.1-svn/lib/libqwt.dylib \ -D QWT_INCLUDE_DIR=/usr/local/qwt-5.2.1-svn/include \ -D GRASS_PREFIX=/user/local/grass-6.4.0 \ .. Snow Leopard note: To handle 32-bit Qt (Carbon), create a 32bit python wrapper script and add arch flags to the configuration: sudo cat >/usr/local/bin/python32 <
