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

 - Fortran compiler (f77, g77, ...) for a few modules
    g77: coming along with gcc

 - GNU make is recommended
    http://www.gnu.org/software/make/make.html

 - zlib compression library (already installed on modern systems)
   It is used to compress GRASS raster files:
    libz: http://www.info-zip.org/pub/infozip/zlib/
          ftp://ftp.freesoftware.com/pub/infozip/zlib/

 - lexical analyzer generator (flex), 
   (lex is no longer supported, please use flex instead)
    flex: http://www.gnu.org/software/flex/flex.html

 - parser generator (yacc, bison)
    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/
      see [http://www.geog.uni-hannover.de/grass/main_tclgrass.html]
 - Mesa-3.x (openGL clone) required for NVIZ2.2
     [http://mesa3d.sourceforge.net/]
     Compile instructions:
     [http://www.geog.uni-hannover.de/grass/grass5/related/README.mesa3d]
 - 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]
 - netpbm-tools/libraries (for r.in.png/r.out.png), usually already installed.
     [please look at any decent software mirror near you!]
     [http://wuarchive.wustl.edu/graphics/graphics/packages/NetPBM]
     [http://www.sourceforge.net/projects/netpbm/]
     
 - libg2c (for r.fill.dir, or use g77)
     [http://?]
     
 - 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)
     Motif or Lesstif libraries required for 
          src.contrib/GMSL/ogl3d
     [http://www.lesstif.org]

 - r.in.gdal requires GDAL - Geospatial Data Abstraction Library
     [http://www.remotesensing.org/gdal/]
