Levent (and Oliver Braun) asked why ffi-using modules are compiled in the install directories (rather than in the build tree and merely copied on install, like everything else). Is that because the alternative doesn't work if your build tree is full of symbolic links, due to path canonicalization?
I think it is currently necessary to install HsFFI.h for ffihugs to work because it expects it to be in {Hugs}/include.
Specifying something like +L'-I$build_dir/includes' when invoking ffihugs might be enough to fix it.
If you wanted to try to overcome this in the C code instead of the makefile, the code is: [...]
I think the Makefile is definitely the place. We can change {Hugs} temporarily by setting the HUGSDIR environment variable.
As far as I know, symbolic links are not an issue (though I guess it's possible).
They are a problem, but it seems I'm the only one using them.
