GCC, the GNU Compiler Collection
The GNU Compiler Collection includes front ends for
C,
C++,
Objective-C, Fortran,
Java, Ada, and Go, as well as libraries for these
languages (libstdc++, libgcj,...).
GCC was originally written as the compiler for the GNU operating system.
The GNU system was developed to be 100% free software, free in the sense
that it respects
the user's freedom.
We strive to provide regular, high quality
releases, which we want to work well on a variety
of native and cross targets (including GNU/Linux), and encourage everyone
to contribute changes or help
testing GCC.
Our sources are readily and freely available via
SVN and weekly
snapshots.
Major decisions about GCC are made by the
steering committee, guided by the
mission statement.
