Eric, thanks for the quick response, that is good news that you are not seeing the problems I see. However after I rebuilt with Apple gcc and still see the errors when calling main from ghci. One is an open ticket, https://ghc.haskell.org/trac/ghc/ticket/9277# which was reported in versions before 7.10.1 so I updated it with the details of my experience. I am running Yosemite 10.10.1. What version are you running? I did notice some difference between our two systems. I have /usr/bin/gcc --version Configured with: *--prefix=/Applications/Xcode.app/Contents/Developer/usr* --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn) Target: x86_64-apple-darwin14.0.0 Thread model: posix while you have *--prefix=/Library/Developer/CommandLineTools/usr* When I try bash-3.2$ xcode-select --install xcode-select: error: command line tools are already installed, use "Software Update" to install updates it doesn't change anything, I still have the above prefix. Also, you are right, my last email had info for the wrong ghc, when I look at the right one and yours I see the following difference. You have ,("LibDir","/Library/Frameworks/GHC.framework/Versions/7.10.0-rc1-x86_64/usr/lib/ghc-7.10.0.20141222") ,("Global Package DB","/Library/Frameworks/GHC.framework/Versions/7.10.0-rc1-x86_64/usr/lib/ghc-7.10.0.20141222/package.conf.d") I have ,("LibDir","/usr/local/lib/ghc-7.10.0.20141222") ,("Global Package DB","/usr/local/lib/ghc-7.10.0.20141222/package.conf.d") I am doing a build by doing the following: $ autoreconf $ ./configure $ make $ make install ​The correct output from ghc --info for me is: ghc --info [("Project name","The Glorious Glasgow Haskell Compilation System") ,("GCC extra via C opts"," -fwrapv") ,("C compiler command","/usr/bin/gcc") ,("C compiler flags"," -m64 -fno-stack-protector") ,("C compiler link flags"," -m64") ,("Haskell CPP command","/usr/bin/gcc") ,("Haskell CPP flags","-E -undef -traditional -Wno-invalid-pp-token -Wno-unicode -Wno-trigraphs ") ,("ld command","/usr/bin/ld") ,("ld flags"," -arch x86_64") ,("ld supports compact unwind","YES") ,("ld supports build-id","NO") ,("ld supports filelist","YES") ,("ld is GNU ld","NO") ,("ar command","/usr/bin/ar") ,("ar flags","clqs") ,("ar supports at file","NO") ,("touch command","touch") ,("dllwrap command","/bin/false") ,("windres command","/bin/false") ,("libtool command","libtool") ,("perl command","/usr/bin/perl") ,("target os","OSDarwin") ,("target arch","ArchX86_64") ,("target word size","8") ,("target has GNU nonexec stack","False") ,("target has .ident directive","True") ,("target has subsections via symbols","True") ,("Unregisterised","NO") ,("LLVM llc command","/usr/local/bin/llc") ,("LLVM opt command","/usr/local/bin/opt") ,("Project version","7.10.0.20141222") ,("Project Git commit id","a8c556dfca3eca5277615cc2bf9d6c8f1f143c9a") ,("Booter version","7.8.3") ,("Stage","2") ,("Build platform","x86_64-apple-darwin") ,("Host platform","x86_64-apple-darwin") ,("Target platform","x86_64-apple-darwin") ,("Have interpreter","YES") ,("Object splitting supported","YES") ,("Have native code generator","YES") ,("Support SMP","YES") ,("Tables next to code","YES") ,("RTS ways","l debug thr thr_debug thr_l thr_p dyn debug_dyn thr_dyn thr_debug_dyn l_dyn thr_l_dyn") ,("Support dynamic-too","YES") ,("Support parallel --make","YES") ,("Support reexported-modules","YES") ,("Support thinning and renaming package flags","YES") ,("Uses package keys","YES") ,("Dynamic by default","NO") ,("GHC Dynamic","YES") ,("Leading underscore","YES") ,("Debug on","False") ,("LibDir","/usr/local/lib/ghc-7.10.0.20141222") ,("Global Package DB","/usr/local/lib/ghc-7.10.0.20141222/package.conf.d") ]​ On Sat, Jan 17, 2015 at 2:38 PM, Erik Hesselink wrote:

Hi George,

I've not tried compiling via llvm, but I have a working Mac GHC 7.10 build that I've been using, and haven't seen any of the other issues you mentioned. I'm not sure what's recommended but I believe I'm using clang (see output below). If you want to try my build, you can download it at [1]. BTW, the info you posted seems to be from 7.8, not 7.10.

Regards,

Erik

GNU gcc 4.9.2 Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)

When using ghci with 7.10.1 RC1 I get the following errors intermittently. Is anybody else seeing these?

Too late for parseStaticFlags: call it before runGhc or runGhcT *** Exception: ExitFailure 1 ld: library not found for -l:ghc31505_10.dylib collect2: error: ld returned 1 exit status phase `Linker' failed (exitcode = 1)

We are pleased to announce the first release candidate for GHC 7.10.1:

https://downloads.haskell.org/~ghc/7.10.1-rc1/

This includes the source tarball and bindists for 64bit/32bit Linux and Windows. Binary builds for other platforms will be available shortly. (CentOS 6.5 binaries are not available at this time like they were for 7.8.x). These binaries and tarballs have an accompanying SHA256SUMS file signed by my GPG key id (0x3B58D86F).

We plan to make the 7.10.1 release sometime in February of 2015. We expect another RC to occur during January of 2015.

Please test as much as possible; bugs are much cheaper if we find them before the release!
