REQUIREMENTS to compile GRASS GIS 6

A workstation running some flavor of UNIX like Solaris, IRIX, Linux, BSD, Mac OS X or cygwin (on Win32). Ideally, you should have at least 500 Mb for data and 32 Mb RAM. The source code package needs around 50 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 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

GNU make is recommended

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

zlib compression library (already installed on most modern systems)

http://www.gzip.org/zlib

flex 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 (already installed on modern systems)

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

X11 window system for graphical output, development libraries (X development libraries, in some linux distributions they are separate packages, e.g. xlibs-dev)

http://www.xfree.org

winGRASS: As alternative a generic MS-Windows driver is under construction which does not require X11

http://mesa3d.sourceforge.net
C++ Compiler (required for the r.terraflow module)
gcc: http://www.gnu.org/software/gcc/gcc.html
