Hmmmm, that's definitely no solution. What platform exactly are you
using? (ghc used for building, gcc version, etc.) Calling make with
EXTRA_HC_OPTS="-v -keep-tmp-files"
and sending the output plus the generated *.hscpp file might help. I
guess that something goes wrong during the preprocessing stage. On a
non-WinDoze platform the last lines of Extensions.hs should expand
into:
foreign import ccall unsafe "glXGetProcAddressARB" glXGetProcAddressARB ::
CString -> IO (FunPtr a)
On WinDoze they should expand into:
foreign import stdcall unsafe "wglGetProcAddress" glXGetProcAddressARB ::
CString -> IO (FunPtr a)
Cheers,
S.
