REQUIREMENTS to compile GRASS GIS 7

A workstation running some flavor of UNIX including GNU/Linux, Solaris, IRIX, BSD, Mac OSX, Cygwin or MinGW (on Win32/Win64). Ideally, you should have at least 800 MB of free disk space. The source code package needs disk space of around 26 MB compressed and 440MB uncompressed. The resulting binaries may need between 20 MB and 180 MB depending on your platform and compiler flags. During a full compilation you may need temporarily up to 550MB including the source code.

To enable and 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
PROJ4 - Cartographic Projection Library
http://trac.osgeo.org/proj
GDAL/OGR for import and export of most external raster and vector map formats

Python >= 2.6 (for temporal framework, scripts, wxGUI, and ctypes interface)
Note: Python 3 support is still in development

Optional requirements:

Note: also the respective development packages (commonly named xxx-dev or xxx-devel) need to be installed.

C++ Compiler (required for the various C++ GRASS module)
