Building Claws Mail with JHBuild -------------------------------- Claws Mail can be built with JHBuild. This way, it's easy to do sandboxed builds, for example in order to try out different versions of low-level dependencies like gtk+ or glib without messing up a production system. It's also useful to build older dependencies that are otherwise hard to get on a more recent distribution. In order to use JHBuild for building Claws Mail, first, JHBuild itself must be built and installed, see https://developer.gnome.org/jhbuild/stable/getting-started.html JHBuild needs a configuration file, either as ~/.jhbuildrc or given with the parameter -f on the command line. You can use the file sample.jhbuildrc-claws-mail as a starting point, but you'll have to modify it to suit your local environment.
