= Compiling under Funtoo-Linux =

The [http://grasswiki.osgeo.org/wiki/Compile_and_Install#Generic_Compilation_and_installation_procedure Generic Compilation & installation procedure] is valid also for the [http://www.funtoo.org/ Funtoo]-Linux meta-distribution. The following example scripts are provided as a mean to get started.


== Installing dependencies ==

''Following likely needs to be updated! ''

== Example Scripts ==

A simple configuration and compilation

{{{
#!div style="font-size:85%"
{{{
#!sh
# clean previous configuration
make distclean

# update source code
svn up

# renice! source: <http://lists.osgeo.org/pipermail/grass-user/2013-May/068229.html>
renice +17 -p $$

# configure
./configure \
--with-freetype=yes --with-freetype-includes="/usr/include/freetype2/" \
2>&1 | tee config_log.txt

# compile
time make -j13
}}}
}}}

An attempt for a complete configuration and compilation '''checking'''. In addition, this script times each of the executed commands (need for scrolling back!).
