REQUIREMENTS to compile GRASS GIS

A workstation running some flavor of unix like Solaris, Irix, Linux, BSD, Mac OS X, CygWindows. Ideally, you should have at least 500 Mb for data and 32 Mb RAM. The source code package needs around 100MB uncompressed. The resulting binaries may need between 80MB and 180MB depending on your platform.

General requirements:

(most tools are standard tools on Linux, for other platforms you may have to install some of them.)

C-compiler (cc, gcc, egcs, ...)

http://www.gnu.org/software/gcc/gcc.html

Fortran compiler (f77, g77, ...) for a few modules

GNU make is recommended

http://www.gnu.org/software/make/make.html

zlib compression library (already installed on modern systems)

http://www.info-zip.org/pub/infozip/zlib/

ftp://ftp.freesoftware.com/pub/infozip/zlib/

lexical analyzer generator (flex),

http://www.gnu.org/software/flex/flex.html

parser generator (yacc, bison)

http://www.gnu.org/software/bison/bison.html

libncurses4.x/5.x

http://www.gnu.org/software/ncurses/ncurses.html

ftp://ftp.gnu.org/pub/gnu/ncurses/

X11 window system for graphical output, development libraries (X development libraries, in some linux distributions they are separate packages)

http://www.xfree.org

Optional requirements:

Tcl/Tk 8.x libraries to use TclTkGRASS Interface and to compile src.contrib/GMSL/NVIZ2.2/

Special compile instructions:
[http://grass.itc.it/grass5/README.mesa31]

FFTW (library for computing the Discrete Fourier Transform) required for i.fft and i.ifft modules
[http://www.fftw.org]

libpng (for r.in.png, r.out.png), usually already installed.
[ftp://ftp.cdrom.com/pub/png/]
libjpeg (for r.in.tiff, r.out.tiff, for HDF library), usually already installed.
[ftp://ftp.uu.net/graphics/jpeg/]
libtiff (for r.in.tiff, r.out.tiff), usually already installed.
[http://www.libtiff.org]

[please look at any decent software mirror near you!]
[http://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM]
[http://www.sourceforge.net/projects/netpbm/]
PostgreSQL libraries (for the PostgreSQL database interface)
[http://www.postgresql.org]
Unix ODBC (for the ODBC database interface)
[http://www.unixodbc.org]
R language (for the R language interface)
[http://cran.r-project.org]
Usually not required (as you will use NVIZ) the Motif or Lesstif libraries required for
src.contrib/GMSL/ogl3d
[http://www.lesstif.org]
r.in.gdal requires GDAL - Geospatial Data Abstraction Library
