Problem building GHC

[aluink]

Here's the summary after the GHC configure. http://pastebin.com/dWvgrd4B

Then well into the compile it fails when trying to build Type.o. http://pastebin.com/p8QdBeqt

I'm running:
GHC 7.6.3
XCode 4.6
PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/Users/e33566p/Library/Haskell/bin:/Users/e33566p/programs/haskell/ios/ghc-ios-scripts:/usr/local/llvm/bin

Not sure what else is pertinent, let me know and I'll post up.

Hi there — can you tell me what version your LLVM install is? We're pretty sure at this point that 3.0 is required and nothing else works (I'm updating the wiki now : ))

[aluink]

I'm running 3.3. Should I wipe and reinstall with 3.0?

[lukexi]

That oughta be it — yeah, for sure!

Ok, giving that a shot. Just to be sure, the following should be sufficient right for the LLVM config? I tried enabling/disabling optimizations previously.

./configure --enable-targets=arm --prefix=/my/prefix

[aluink]

Hmm, seems 3.0 has a compile error. Now I need to figure out how to compile with GCC.

I built llvm 3.0 from source using just ./configure --prefix=/my/prefix and it gave me all the targets. Make sure you have x86 as well as arm.

[the-real-blackh]

...actually I would have used gcc because I'm on Mountain Lion and the default system compiler is still gcc.

stephen-blackheaths-mac-mini:~ blackh$ gcc --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

[aluink]

Hmm, setting CC=gcc and CXX=g++ "fixed" it.

[aluink]

Well, guess it wasn't fixed. GHC compilation failed after about 2hrs with a whole bunch of "ARM function not 4-byte aligned" warnings. I'm rebuilding LLVM with x86,arm targets. Then I'll try it again.

Hi Eric,
2 things — you can just download LLVM 3.0 binaries here and drop them in your path:
​http://llvm.org/releases/3.0/clang+llvm-3.0-x86_64-apple-darwin11.tar.gz

Also those “not 4-byte aligned” warnings are normal and usually don’t affect anything (so there is probably another error)

Cheers
Luke

Alright, I got it working and verified in the simulator. I'll be posting a blog post outlining my steps in detail for the community to have.
