I haven't uploaded my WIP version yet (I've got half into qrexec packaging), but I did improved makefile in qubes-core-vchan-xen upstream. On camp we've hit various issues about library paths (pkgconfig file, include etc). Now it's possible to put them in /lib /include etc, instead of /usr, with a PREFIX=/.

And thanks for pushing it here!

So this just seem to be some header files and nothing else? so not much to review then I guess

[marmarek]

There should be a library (.so) too.
