Sandybridge configuration incorrect for recent Mac OS X

[poulson]

Because of the fact that Apple chose to alias gcc to clang and g++ to clang++, the current Sandybridge configuration,

blis/config/sandybridge/make_defs.mk

Line 79 in ec25807

CC := gcc

, will fail since Clang does not (yet) support OpenMP.

While I think it is despicable behavior on Apple's part, why does anyone rely on executable name to identify the compiler? $(CC) --version is more reliable.

I've worked around this issue in the following PR: #28

It seems that either libtool or install_name_tool still needs to be used so that the proper paths are searched. At the moment, otool -L on the installed blis library is clearly insufficient:

$ otool -L ~/Install/clang-3.6/mpich-3.1.4/lib/libblis.dylib 
/Users/poulson/Install/clang-3.6/mpich-3.1.4/lib/libblis.dylib:
    lib/sandybridge_osx_clang/libblis.dylib (compatibility version 0.0.0, current version 0.0.0)
    /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1213.0.0)

This changeset appears to have fixed the issue: scibuilder@2d7d5bf
