ORM.Model fails to compile on OSX (ghc-clang-wrapper present)

[ret]

Hi Amit, looking for help with this OSX specific issue below. Works like a charm on Ubuntu, but bombs with a parse error on OSX. I've got the ghc-clang-wrapper in place (otherwise there's no way to get this far in the first place ;-)). Does this ring any bell?

Thanks, Reto

@ret this was a known bug. Are you compiling v0.3.0 from hackage or git tip? Should be fixed in both. Could you try compiling from git tip if you haven't?

[ret]

I just tried from the git tip and used the naive commands below (ghc is 7.6.3, cabal is 1.20.0.0). Still hitting the same 'where' clause error. How can I help debug this further (feeling bad imposing on your time for something this basic)?

:) Please don't be sorry. It's a bug in the code and we need to fix it, so appreciate the feedback. It's almost certainly a CPP bug (there is apparently some discrepancy between GCC's preprocessor and LLVM's clone, and it looks like GCC accepts slightly buggy CPP). I don't have access to an OS X machine just now, but will fix this when I do again tonight.

OK this is fixed.

@ret please try again and reopen if any issues but I confirmed the bug and then the fix on my machine.

Thanks guys! Works like a charm now.
