Care to take at stab at writing them?Sorry, I looked a bit in the t/ directory but my eyes glazed over. Perhaps I am not the best person to attempt those.It's OK if you can just post the snippets of relevant vala sources and build options exposing the problem, and describe the steps to reproduce such a problem. I can synthesize a test case from there myself then.It was exposed by a builddir != srcdir problem in gsound in gnome git https://git.gnome.org/browse/gsound/ (linked bugreport above) where a test program (gsound-play.vala) needs the gsound vapis which are also a build product. The way to reproduce it is: - autogen gsound with the workaround (4f8a78c) removed - mkdir _build & cd _build - ../configure - notice how the gsound-play compile fails in the _srcdir_ (because of the the "am__cd") but its arguments are trying to use ../gsound instead of the builddir gsound Hope that helps.

Since I know almost nothing about Vala, and I'm short of time these days, I don't think I will go perusing into a third-party project to find a test case; a minimal reproducer in form of Vala sources, a Makefile.am fragment, and an high-level description of the expected behavior) would be appreciated, and would help in speeding up the fix. Thanks, Stefano
