Re: Problem with cabal's --enable-library-coverage on 7.8.1rc2

Ok. What cabal package? Have you filed a bug report on ghc trac? On Sunday, March 9, 2014, Federico Mastellone wrote:

Downloaded gcc-4.9 binary from http://hpc.sourceforge.net and tested again with both 7.6.3 and 7.8-rc2

Fails with the same error with 7.8-rc2 and does not fail with 7.6.3

No. Try real GCC. Follow my linked directions. Xcode GCC is fake. It's clang. Follow my directions please.

It’s the same error with and without the clang-xcode5-wrapper that is named as an alternative solution

Hi,

On Mac OS X 10.9.2 with ghc 7.8.0.20140228 and cabal 1.18.0.3

Doing: cabal configure --enable-library-coverage cabal build

Fails with:

ld: illegal text reloc in '_enablezmlibraryzmcoveragezm0zi0zi1_Library_sendMsg2_info' to '__hpc_tickboxes_enablezmlibraryzmcoveragezm0zi0zi1_Util_hpc' for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

But without the coverage flag it’s OK.

I found it when switching from 7.6.3 to 7.8.1RC2 on a project I have and was able to strip it to this: https://github.com/fmaste/ghc-7.8.0.20140228-enable-library-coverage

Don’t know if this is a cabal or ghc problem and I don’t know how to continue.

Thanks!
