Re: [Haskell-cafe] how ghc finds libgmp.so when linking

more data:

when I compile with -optl -L/usr/local/lib, then the correct library is found,

when I put ("ld flags", "-L/usr/local/lib") in ghc-7.10.3/settings, then it's not,

when I put ("C compiler link flags", "-L/usr/local/lib") in settings, then it is.

So, I can leave it at that. But I still don't know how this came to be. I built this ghc-7.10.3 from source.

I get ld: warning: directory not found for option '-L/opt/local/lib/' when using hmatrix but I have no idea why. Perhaps the error messages are not related.
