Now I have tried to build the CVS head in Cygwin, using both gcc 2.95 and gcc 3.1 and both a Cygwin and a Mingw version of the compiler, I give up... The reason that this post is found here is simply because I need to test out the Template Haskell implementation. Anyone else having tried to build it using Cygwin? I would love to have it up and running on a box beside my Linux one... Using "./configure --build=i386-unknown-mingw32" with a 2.95 Mingw gcc I get the following error: ../../ghc/compiler/ghc-inplace -H16m -O -fglasgow-exts -cpp -Iinclude -#includ HsBase.h -Icbits/regex -funbox-strict-fields -package-name base -O -Rghc-timin -split-objs -c Foreign/Storable.hs -o Foreign/Storable.o -ohi Foreign/Sto ble.hi Foreign/Storable.hs:179: Type constructor or class not in scope: `NotReallyAType' Foreign/Storable.hs:180: Type constructor or class not in scope: `NotReallyAType' Foreign/Storable.hs:181: Type constructor or class not in scope: `NotReallyAType' Foreign/Storable.hs:182: Type constructor or class not in scope: `NotReallyAType' make[2]: *** [Foreign/Storable.o] Error 1 make[1]: *** [all] Error 1 make[1]: Leaving directory `/lang/haskell/ghc/fptools/libraries' make: *** [build] Error 1
