Ideally, you should have at least 500 Mb for data and 32 Mb RAM. The source code package needs around 100 MB uncompressed. The resulting binaries may need between 80 MB and 180 MB depending on your platform. During a full compilation you need temporarily 550MB including the source code. <p> To disable features please read the INSTALL file. <br> <h3>General requirements:</h3> (most tools are standard tools on Linux, for other platforms you may have to install some of them.) <ul> <li>C-compiler (cc, gcc, egcs, ...)</li> <br>gcc: <a href="http://www.gnu.org/software/gcc/gcc.html">http://www.gnu.org/software/gcc/gcc.html</a> <br><br> <li>GNU make is recommended</li> <br><a href="http://www.gnu.org/software/make/make.html">http://www.gnu.org/software/make/make.html</a> <br><br> <li>zlib compression library (already installed on modern systems)</li> <br>It is used to internally compress GRASS raster files: <br>libz: <a href="http://www.gzip.org/zlib/">http://www.gzip.org/zlib/</a> <!-- freesoftware.com is broken! <br><a href="ftp://ftp.freesoftware.com/pub/infozip/zlib/">ftp://ftp.freesoftware.com/pub/infozip/zlib/</a> --> <br><br> <li>lexical analyzer generator (flex),</li> <br>(lex is no longer supported, please use flex instead) <br>flex: <a href="http://www.gnu.org/software/flex/flex.html">http://www.gnu.org/software/flex/flex.html</a> <br><br> <li>parser generator (yacc, bison)</li> <br>bison: <a href="http://www.gnu.org/software/bison/bison.html">http://www.gnu.org/software/bison/bison.html</a> <br><br> <li>libncurses4.x/5.x (already installed on modern systems)</li> <br><a href="http://www.gnu.org/software/ncurses/ncurses.html">http://www.gnu.org/software/ncurses/ncurses.html</a> <br><a href="ftp://ftp.gnu.org/pub/gnu/ncurses/">ftp://ftp.gnu.org/pub/gnu/ncurses/</a> <br><br> <li>dgm/gdbm (dbm.h): GNU dbm is a set of database routines that use extendible hashing and works similar to the standard UNIX dbm routines.
