Windows: pkg-config reports missing x11

[Mikolaj]

When compiling the following on Vista or on Wine (details for Wine at http://www.haskell.org/haskellwiki/GHC_under_Wine#Code_that_uses_gtk2hs)

cabal install LambdaHack-0.4.99.0

cabal reports

setup-Cabal-1.18.1.3-i386-windows-ghc-7.8.3.exe: The pkg-config package x11 is required but it could not be found

The following workaround works on both Vista and Wine (in the latter case, the binary, obtained after a few more workarounds, is confirmed to run correctly; for Vista, I've lost patience).

cp ~/.wine/drive_c/users/mikolaj/gtk/lib/pkgconfig/fontconfig.pc ~/.wine/drive_c/users/mikolaj/gtk/lib/pkgconfig/x11.pc

I'm only guessing it's a gtk2hs bug, and not GHC's nor cabal's.

Do you know which of the gtk2hs packages it was installing at the time? Gtk2hs runs pkg-config to get the C flags and linker flags to use (it looks up the packages that are in the pkgconfig-depends in the cabal file). I suspect it is looking for the flags for gtk+-3.0 and that there might be a dependancy (perhaps indirectly) in gtk+-3.0.pc on x11.pc.

What happens if you just run...

pkg-config --cflags gtk+-3.0

[Mikolaj]

Ugh, it's actually all my fault. I have

pkgconfig-depends: gtk+-2.0, x11

in my .cabal file, copied from somewhere on the net. Gtk2hs alone installs fine, just tried.
Sorry for the noise and thank you. Closing.
