Hi, To test the coming GHC 7.8.3, I started to use the latest ghc-7.8 branch. Unfortunately, on my Mac, I saw many warnings which are not displayed with GHC 7.8.2: clang: warning: argument unused during compilation: '-fno-stack-protector' clang: warning: argument unused during compilation: '-D TABLES_NEXT_TO_CODE' clang: warning: argument unused during compilation: '-I test' clang: warning: argument unused during compilation: '-I dist/build/spec/spec-tmp' clang: warning: argument unused during compilation: '-I dist/build/spec/spec-tmp' clang: warning: argument unused during compilation: '-I dist/build/autogen' clang: warning: argument unused during compilation: '-I dist/build/spec/spec-tmp' Is this a known issue? --Kazu
Hi, Also I found that GHC 7.8.2 can compile yesod-bin but GHC 7.8.3 cannot: ---- [ 1 of 10] Compiling GhcBuild ( GhcBuild.hs, dist/build/yesod/yesod-tmp/GhcBuild.o ) GhcBuild.hs:150:55: Couldn't match type ‘Phase’ with ‘Bool -> Phase’ Expected type: [(String, Maybe (Bool -> Phase))] Actual type: [(String, Maybe Phase)] In the second argument of ‘partition’, namely ‘srcs’ In the expression: partition haskellish srcs ...

Hi, I don't know whether or not this is new but it's worth sharing.

Is this a known issue?
This is due to clang of Xcode 5.1. I found that the "-Qunused-arguments" option of clang disables these warnings. I think that "ghc-clang-wrapper" should include this option. --Kazu
Would this fix #9047? Yay!

Hi, Cloning the fresh GHC source, I can validate GHC HEAD on Linux. And I understand "install dir" is correct. The problem on Mac is that "ghc-clang-wrapper" is a shell script. I cannot find a way to treat strings, which includes spaces, correctly with shell scripts. So, I replaced "install dir" to "install_dir" in three files and can validate GHC HEAD on Mac finally. Questions: * What is the purpose of spaces in "install dir"? * Would you tell me the plan to provide C preprocessor program by GHC itself? --Kazu

I'm the source of ghc-clang-wrapper. I can add "-Qunused-arguments" easily enough. I just last night ran across the spaces problem - and I'm not entirely sure the bug is in ghc-clang-wrapper! I'll investigate... turns out all you need to do is try to compile something that is in a directory with spaces in it. - Mark
Hi Mark,
I've already merged two changesets into 7.8.3 -
https://github.com/ghc/ghc/commit/52222f9e0bedc9b08b46619f8ed4d09f645d6ed4
and https://github.com/ghc/ghc/commit/fd4169f9caf6922e3e5ea9c31f497f7220fc62b8
- which add -Qunused-arguments to the C compiler invocation if the
compiler is Clang. The GHC but is #9047
(The problem was Clang will ignore a lot of the flags we pass in the
assembler stage, since it will be used as the assembler). So I don't
think a workaround will be needed.

Great. I confirmed that I can validate both GHC HEAD and the ghc-7.8 branch on Mac WITHOUT ghc-clang-wrapper. --Kazu
I ran a validate myself on OS X this evening, i can confirm things worked
too :)
