ghc-xcode's Issues

Automate linker flags

We should pull linker flags (for example, -liconv) from the GHC packages and automatically display them to the user.

Currently, -liconv is hard-coded.

Handle ghc warnings better

Warnings from GHC are handled inconsistently and not always displayed in the build log.
I haven't track down the cause of this issue yet.

It might also help to emit them in a format which is parseable by Xcode, like we do for errors.

Don't require -no_pie on some versions of GHC

It looks like -no_pie might not be necessary on ghc>=7.4.1, since the local version of gmp has that problem fixed.

If so, ghc-xcode should not print that flag when using a version of ghc which is recent enough.

Xcode unnecessarily recompiles C/Objective-C files

It looks like Xcode recompiles every C/Objective-C source file (including the precompiled header?) after ghc-xcode runs.

In practice this isn't always a problem since Xcode seems to do some of that compiling in the background.

I'm not sure whether this is something triggered just by using custom build phases or by the FFI headers being rewritten each time.

Print a message as we recompile each Haskell module

ghc-xcode currently does not print anything while it compiles Haskell modules. It should act more like GHC, which prints a status message as it recompiles each file.
