Fails to build on MacOS

[peregrinrm]

Hi!

I want to build the docs to have a local version, however building the docs seem to require building the whole system.

I have a Macbook Pro with MacOS High Sierra, with Xcode, and the julia build always fails with:

/Applications/Xcode.app/Contents/Developer/usr/bin/make -C scratch/openblas-e8a68ef261a33568b0f0cf53e0e2287e9f12e69e/ CC=clang -stdlib=libc++ -mmacosx-version-min=10.8 -m64 FC=gfortran -mmacosx-version-min=10.8 -m64 LD=ld RANLIB=ranlib TARGET= BINARY=64 USE_THREAD=1 GEMM_MULTITHREADING_THRESHOLD=50 NUM_THREADS=16 NO_AFFINITY=1 DYNAMIC_ARCH=1 INTERFACE64=1 SYMBOLSUFFIX=64_ LIBPREFIX=libopenblas64_ OBJCONV=/Users/peregrin/src/julia/deps/scratch/objconv/objconv CFLAGS= -O2 FFLAGS= -O2 -fPIC LDFLAGS= -Wl,-rpath,'@loader_path/' MAKE_NB_JOBS=0

Can you help me?

I've submitted a PR (#29845) that updates the version of OpenBLAS used by Julia, which fixed this issue for me. Could you try building the aa/openblas-0.3.3 branch to confirm that it fixes the issue for you as well?

Should be fixed by #29845, which has now been merged. Let me know if you still can't build master.
