We use Git to maintain our source code, in the GNOME Git repository. Additional information about is available at

glibmm and gtkmm are in the glibmm and gtkmm modules. There is also a gtkmm-documentation module which contains the gtkmm book and its examples. See below for instructions.

Meson is the recommended build system. If you build with Autotools (autoconf, automake,etc.), you will need to run the script to generate the build files. We recommend jhbuild or gnome-build-meta for setting up a separate development prefix.

Anonymous Access

For those who do not have a GNOME login, anonymous checkouts are available.

For instance, to check out the latest version of gtkmm:

git clone
