I thought that I had fixed all this for Gtk+HS. (In fact, all Gtk+HS examples are running fine with GHC 4.08 on my machine.) Have a look at the file gtk+hs/gtk/ghcRtsAux.c. It defines rts_mkPtr in a somewhat nasty way, but it works :-)

I've seen the hack, but on another box freshly installed ghc-4.08.2, c2hs from tarball and gtk+hs from tarball did not work (linker can't find rts_mkPtr). I must see if ghcRtsAux.c is compied at all there.

Strange - meanwhile, I have put release 0.10.4 out. Among other things, it finally has an `install' target.

PS: With the current Gtk+HS source in CVS, all Gtk+HS examples as well as the iHaskell library and its three examples should now all work again. I tested it all on my machine.

ghc version check fails on 4.11 (it should be lexicographic comparison of version number components, not conjunction of independent comparisons).

Checking for buggy readXXXOffAddr (for ghc-4.03..4.06) is now unnecessary as gtk+hs requires ghc-4.08.1 anyway.

Ok, I fixed these.

They compile but they don't run correctly on ghc-4.11. It's because GMarsh.writeCharOffAddr does not simulate Addr.writeCharOffAddr when Char is wide, because instance Storable Char treats Char as wide. You need to cast to CChar, Word8, or Int8 (be careful with sign extension).

`castCCharToChar' and `castCharToCChar' should be sufficient here, right? I have added them in the 0.10.4 release. Thanks, Manuel
