REQUIREMENTS to compile GRASS GIS

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 80 MB uncompressed. The resulting binaries may need between 20 MB and 180 MB depending on your platform. During a full compilation you need temporarily 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 modern systems)

http://www.gzip.org/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 (already installed on modern systems)

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, e.g. xlibs-dev)

http://www.xfree.org

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

PROJ4 - Projection Library

Optional requirements:

Tcl/Tk 8.x libraries (they include 'wish') to use TclTkGRASS Interface and to compile src.contrib/GMSL/NVIZ2.2/

LAPACK / BLAS (libraries for numerical computing) required for GMATH library (GRASS numerical lib)
[http://www.netlib.org/lapack/] (usually on Linux distros)
Note: the support is intended for future module implementations
libpng (for r.in.png, r.out.png), usually already installed.
http://www.libpng.org/pub/png/libpng.html
