REQUIREMENTS to compile GRASS GIS 6

A workstation running some flavor of UNIX like Solaris, IRIX, GNU/Linux, BSD, Mac OS X, Cygwin or MinGW (on Win32). Ideally, you should have at least 500 Mb. The source code package needs around 80 MB uncompressed. The resulting binaries may need between 20 MB and 180 MB depending on your platform. During a full compilation you may need temporarily up to 550MB including the source code.

To disable features please read the INSTALL file.

General requirements:

(most tools are standard tools on GNU/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
GNU make is recommended (at least version 3.81)
http://www.gnu.org/software/make/make.html
zlib compression library (already installed on most modern systems)
It is used to internally compress GRASS raster maps:
libz: http://www.zlib.net
flex lexical analyzer generator (flex) - note: 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 (already installed on modern systems)
http://www.gnu.org/software/ncurses/ncurses.html
ftp://ftp.gnu.org/pub/gnu/ncurses
X Window system for graphical output, development libraries (X development libraries, in some linux distributions they are separate packages, e.g. xlibs-dev or x11-server-devel)
http://www.xfree.org
http://www.x.org
winGRASS note: As alternative a generic MS-Windows driver is under construction which does not require X11
PROJ4 - Projection Library
http://trac.osgeo.org/proj
GDAL and OGR for import and export of most external raster and vector map formats
http://gdal.osgeo.org

Optional requirements:

Tcl/Tk 8.x libraries (including the 'wish' program) to use the GRASS GUI menu system and the NVIZ visualization suite
Some features of the new gis.m GIS manager may depend on version 8.4 or newer.
see http://tcl.sourceforge.net
If hardware openGL support is missing in the X Server, Mesa-3.x (openGL clone) may be required for NVIZ
http://mesa3d.sourceforge.net
C++ Compiler (required for the r.terraflow module)
gcc: http://www.gnu.org/software/gcc/gcc.html
FFTW 2.x or 3.x (library for computing the Discrete Fourier Transform), required for i.fft and i.ifft and other modules
http://www.fftw.org
LAPACK / BLAS (libraries for numerical computing) for GMATH library (GRASS numerical lib)
http://www.netlib.org/lapack (usually available on Linux distros)
Note: LAPACK/BLAS support is intended for future module implementations, no need to use it at time!
libpng (for r.out.png and the PNG driver), usually already installed.
http://www.libpng.org/pub/png/libpng.html
libjpeg (for r.out.tiff), usually already installed.
http://www.ijg.org
ftp://ftp.uu.net/graphics/jpeg
libtiff (for r.out.tiff), usually already installed.

Motif or Lesstif libraries (for the "xganim" module)
http://www.lesstif.org
R language (for the R statistical language interface)
http://cran.r-project.org

http://www.freetype.org
Python >= 2.4 (for wxGUI)
Note: Python 3 is not supported
http://www.python.org
wxPython >= 2.8.1.1 (for wxGUI, see file gui/wxpython/README)
http://www.wxpython.org
NumPy (for wxPython-based GUI tools, see file gui/wxpython/README)
http://numpy.scipy.org
FFMPEG (for direct rendering of animations from NVIZ), including libavcodec, libavformat, libswscale
http://ffmpeg.mplayerhq.hu
Cairo >= 1.5.8 (Cairo graphics library
http://cairographics.org
AVCE00 and E00Compr Libraries (avcimport)
