Trabajar con el código fuente de gtkmm
Si está interesado o interesada en ayudar con el desarrollo de gtkmm, o arreglar un error en gtkmm, probablemente necesite construir la versión de desarrollo de gtkmm. Sin embargo, no debe instalar una versión de desarrollo sobre su versión estable. En su lugar, debe instalarla junto a su instalación de gtkmm existente, en una ruta separada.
The easiest way to do this is using jhbuild. jhbuild is a program that makes building GNOME software much easier by calculating dependencies and building things in the correct order. This section will give a brief explanation of how to set up jhbuild to build and install gtkmm from the source repository (git). For up-to-date information on jhbuild, please refer to the jhbuild manual.
Note that to build gtkmm from git, you'll often need to build many of its dependencies from git as well. jhbuild makes this easier than it would normally be, but it will take quite a while to build and install them all. You will probably encounter build problems, though these will usually be corrected quickly if you report them.
gnome-build-meta is an alternative to jhbuild. It is described at the Building system components wiki page, but here we concentrate on jhbuild.
