Did you set WXWIN to the correct value, something like:

Another reason why the compilation failed, might be that the configuration  
file specifies a debug build, instead of a release build.

You can build a 64 bit wxHaskell, even though there is a 32 in the name  
mingw32-make; take care that you build wxWidgets with the same bitness. To  
build wxWidgets as 64 bits DLLs, I changed some values in  
build\msw\config.gcc to:

   # Standard flags for CC
   CFLAGS ?= -m64

   # Standard flags for C++
   CXXFLAGS ?= -m64

   # Standard preprocessor flags (common for CC and CXX)
