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!
