Re: 7.8 Release Update

Hello Mikhail, It is a known issue that Template Haskell does not work with profiling (because GHCi and profiling do not work together, and TH uses GHCi's linker). [1] Actually, with the new linker patches that are landing soon we are not too far off from having this work.

Hi,

I think Kazu is saying that when he builds something with profiling using cabal-install, it fails because cabal-install tries to build a dynamic version too. We don't want dyanmic/profiled libraries (there's no point, you can't load them into GHCi). Perhaps this is something that needs fixing in cabal-install?

Aren't they needed when compiling libraries that are using Template Haskell for profiling? The issue sounds like it could be TH-related.
