Welcome to the GCC home page!

GCC, the GNU Compiler Collection, includes front ends for C, C++, Objective-C, Fortran, Java, and Ada, as well as libraries for these languages (libstdc++, libgcj,...).

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 and 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.

February 06, 2005

gcc.gnu.org suffered hardware failure and had to be restored from backups. We do not believe any data was lost in the CVS repository. We did lose any pending messages in the mail queue as that does not get backed up. At this time, everything should be functional except for htdig. The mailing list archives on the web site are also out of date and will be updated soon. New mail will update the archives correctly, however. If you find any other problems, please email overseers@gcc.gnu.org
