Bug 213614 – [JHBuild] Add support for using a minimal moduleset

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Carlos Alberto Lopez Perez]

We would like to be able to build WebKit on a given distribution using as much libraries from the system as possible.
So the idea is to have a minimum JHBuild moduleset for building only the libraries that are not available on the distribution.

I think there's an option in jhbuild to prefer system modules when the version is newer than the one in the moduleset.

Right. But AFAIK that doesn't work for what I intend to do here.

AFAIK <systemmodule ...> tells JHBuild that the dependency should be installed by the system (distro package), and if is not installed then JHBuild will fail. In other words: with systemmodule, jhbuild won't build the dependency if the system doesn't provide one new enough. It will simply fail.

What I'm trying to do here is to tell JHBuild to check if the system provides a new enough version of the dependency, and if it does then skip building it. If it doesn't then JHBuild will build it, instead of failing.

This is achieved by using the <pkg-config> directive in the modules
