What would it entail to use 3.52 on Windows? Just not installing the prebuilt wheel?

I think that should work, but we might end up with a surprise :)

It's not fully working. There's an issue with finding typelibs.

Hi @amolenaar, I isolated this issue to needing to set the GI_TYPELIB_PATH environment variable. This seems like a regression to me in gobject-introspection. It should automatically search for the typelibs in the lib\girepository-1.0 directory, since that is the normal search path.

That's this line in gobject-introspection? This is also in girepository (I think).

>>> from gi.repository import GIRepository
>>> GIRepository.Repository().get_search_path()
['/opt/homebrew/Cellar/glib/2.84.0_1/lib/girepository-1.0', '/opt/homebrew/lib/girepository-1.0']

Edit: GOBJECT_INTROSPECTION_RELATIVE_LIBDIR is set to libdir. Does this make it point to the wrong directory? It points to Lib.

The default path is set to C:\\Users\\gapho\\Development\\gaphor\\.venv\\Scripts\\lib\\girepository-1.0, while with gobject-introspection it's set to C:\\gtk\\lib\\girepository-1.0.

@danyeaw I found the issue. Quick fix is to add a -DDLL_EXPORT CFlag when compiling glib. The real fix is, I think, to remove the check for the DLL_EXPORT variable.

@amolenaar Nice find!
