Mac 10.9 Compilation Issue: llvm won't compile?

[gibiansky]

I run make after having downloaded Julia from HEAD and get the following error (after some lengthy compilation):

/usr/local/bin/cp: cannot stat ‘/Users/silver/dev/julia-src/deps/llvm-3.3/build_Release/lib/Target/X86/Release/X86GenRegisterInfo.inc.tmp’: No such file or directory
make[6]: *** [X86GenRegisterInfo.inc] Error 1
make[5]: *** [X86/.makeall] Error 2
make[4]: *** [Target/.makeall] Error 2
make[3]: *** [all] Error 1
make[2]: *** [llvm-3.3/build_Release/Release/lib/libLLVMJIT.a] Error 2
make[1]: *** [julia-release] Error 2
make: *** [release] Error 2

If I then cd deps and then make (in that dir), it seems to work (at least it doesn't give this error). It then gives an error about OpenBlas... (which doesn't let me make TARGET=HASWELL)

1. Run make distclean to reset Julia to pristine checkout state

2. Please remove your llvm-config script from `/usr/local/bin/

3. Run make -C deps install-llvm to ensure that LLVM itself can be installed

If that works,

4. Run make OPENBLAS_TARGET_ARCH=HASWELL. Note however that OpenBLAS in this case is version 0.2.8, it's not HEAD like you were installing via brew. To get the latest version of OpenBLAS, you need to go into deps/Versions.make and change the v0.2.8 to master develop. That will hopefully dodge the haswell bug on OpenBLAS.

[gibiansky]

Did everything, but make TARGET=HASWELL still doesn't work, even on HEAD of OpenBLAS... :(

[staticfloat]

So you ran make OPENBLAS_TARGET_ARCH=HASWELL in the Julia directory, after editing deps/Versions.make? Sorry to ask the same question again, your last comment is a little unclear to me. Also, is LLVM still failing, or is it working?

[gibiansky]

Ah, sorry I wasn't clear. LLVM works now. So, I guess it's the fact that I had brews llvm linked. So I guess we can close this issue.

However, though LLVM worked, I replaced the openblas line in Versions.make with OPENBLAS_VER = master, ran with make OPENBLAS_TARGET_ARCH=HASWELL, and OpenBlas still claims

20 errors generated.
make[3]: *** [getarch_2nd] Error 1
Makefile:129: *** OpenBLAS: Detecting CPU failed. Please set TARGET explicitly, e.g. make TARGET=your_cpu_target. Please read README for the detail..  Stop.
*** Clean the OpenBLAS build with 'make -C deps clean-openblas'. Rebuild with 'make OPENBLAS_USE_THREAD=0 if OpenBLAS had trouble linking libpthread.so, and with 'make OPENBLAS_TARGET_ARCH=NEHALEM' if there were errors building SandyBridge support. Both these options can also be used simultaneously. ***
make[2]: *** [openblas-master/libopenblas.dylib] Error 1
make[1]: *** [julia-release] Error 2

[staticfloat]

Oh. I am such a fool. You need to set OPENBLAS_VER = develop, not master.

[gibiansky]

Oh! Sorry, I have never dealt with Versions.make :) It is actually doing something now instead of failing immediately. Will report once compiles or fails.

[gibiansky]

Everything seems to work now with the normal Julia compilation. So I guess I had to:

• brew unlink llvm
• Change OPENBLAS_VER to OPENBLAS_VER = develop in Versions.make

After which everything worked; Julia compiles from source and runs.

[staticfloat]

Great. Now let's go back to the other issue, and see if we can apply this to that problem.
