Downloading the library
The current release tarball is available on SourceForge, just click the giant green button.
Note: since it produces an about 30% smaller file than bzip2, the tarball was compressed with lzma2. Please untar using
tar -xvJf cocolib-release-5.tar.xz
Tarballs for previous releases are also available in the downloads section.
Latest developer version
You can always get the latest development version via subversion here:
svn checkout svn://svn.code.sf.net/p/cocolib/code/trunk cocolib-dev
It may or may not compile at any given moment, but usually does. Furthermore, it often contains interesting new algorithms or bugfixes scheduled for a later release.
That being said, new users should probably first try the official release.
