It should work if you provide two .gir, in what sense "it doesn't work"? > 2. use the gir directly : valac does read metadata files, and thus is > able to use the gir directly.

There's no plan to install metadata until we don't have any in the vala tree itself, at least for now. In the switch-to-gir branch there's a patch for --metadatadir option. > * Is it a good idea to include (but not install) a metadata file for > gtk, to work around bugs? (such as 635287) As said before, yes makes sense but as vala still uses .gi there's no plan for that yet. > As an aside, while trying the second solution, valac crashed, and when I > tried the first one, I got the "missing class prerequisite" error, > looking through the git log I found that the fix for bug 624923 got > reverted by commit fc7fe82fbd0b19b6caaf (the commit message suggests > this code should be moved after symbol resolution, but only deletes it). > Reverting that commit fixed both. True, that should have been re-fixed due to the refactoring and totally forgot that, shame on reviewers :P (and on me). > I guess the bug should be reopened (or a new one opened) if there is a > problem with the patch.
