== General Info ==

Ubuntu 8.04LTS installs 64 bit libs into /lib and 32 bit libs into /libs32 unlike the standard which suggests 64 bit libs in /lib64 and 32 bit libs in /lib. That leads to build failures of stock gcc releases. http://gcc.gnu.org/ml/gcc-help/2006-06/msg00071.html offers a solution:
{{{
Those "manual fixes" to the sources are quite obvious though, the "target Makefile
fragment", 'gcc/config/i386/t-linux64', has in it :

 MULTILIB_OPTIONS = m64/m32
 MULTILIB_DIRNAMES = 64 32
 MULTILIB_OSDIRNAMES = ../lib64 ../lib

and changing this into :

 MULTILIB_OPTIONS = m64/m32
 MULTILIB_DIRNAMES = 64 32
 MULTILIB_OSDIRNAMES = ../lib ../lib32
}}}

Please ping mabshoff in IRC or per email if you need any other gcc compiler, i.e. additional Fortran compilers or specific release.

== Installed Compilers ==

=== System Compiler ===
This one might get upgrade as time progresses:
{{{

=== gcc 4.0.4 ===

Build with C and C++ support:
