Releases are available by source branch checkout and ftp tarball. For example, to download the 2.17 release, checkout the libc branch release/2.17/master, and similarly for all required add-ons including ports. After the 2.17 release the contributed ports add-ons have been folded into the main git repo and no longer need to be checked out separately.
e.g.
git clone git://sourceware.org/git/glibc.git cd glibc git checkout --track -b local_glibc-2.17 origin/release/2.17/master
To list the current set of branches use:
git branch -a
Releases and pre-releases are available via anonymous ftp at http://ftp.gnu.org/gnu/glibc/ and its mirrors.
You can access the development source tree using git.
git clone git://sourceware.org/git/glibc.git [gitweb]
To additionally fetch the contributed ports add-on (for 2.16 and older release branches, see also README.ports-moved-to-libc):
git clone git://sourceware.org/git/glibc-ports.git [gitweb]
If you have any questions about the contributed ports add-on please send email to libc-ports. Please do not send mail to libc-alpha.
