The SQLite++ source code could be obtained through our git repositorie in Gitorious or in the SourceForge with the bellow links:
Public Git Clone URL
git clone git://gitorious.org/sqlitepp/mainline.git sqlitepp
HTTP Git Clone URL
git clone http://git.gitorious.org/sqlitepp/mainline.git sqlitepp
(note that cloning over HTTP is slightly slower, but useful if you’re behind a firewall)
