GCC, the GNU Compiler Collection

The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Java, Ada, and Go, aswell as libraries for these languages (libstdc++, libgcj,...). GCC was originally written as the compiler forthe GNU operating system. The GNU system was developed to be 100% free software, free in the sensethat 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 andcross targets (including GNU/Linux), and encourage everyone to contributechanges or help testingGCC.Our sources are readily and freely available via SVNand weekly snapshots.

Major decisions about GCC are made by the steering committee, guided by the mission statement.
