OS X clang compiler look up.

OS X Version 10.9.5 with XCode w/ command line tools installed.

$ pip install uwsgi
build/uwsgi/uwsgiconfig.py", line 692, in __init__
    gcc_major = int(gcc_version.split('.')[0])
AttributeError: 'NoneType' object has no attribute 'split'

    raise Exception("you need a C compiler to build uWSGI")

Since clang is default is default since a few (xcode 4.2 afaik) on mac os x, wouldn't be saner to go straight with clang / llvm-something on darwin instead? FYI On linux clang 3.5.0 reports 4.2.1 with -dumpversion.

@xrmx the problem is that we "should" try to use the same compiler used to build python, and often this is not available on the system

Any status on this PR? Wondering if there is a plan to fix compilation on OS X.

Thank you

Some additional info on the problem..

>>> os.environ.get('CC', sysconfig.get_config_var('CC'))`
gcc-4.2
>>> spcall('llvm-gcc-4.2 -dumpversion')
None

Results in a compiler not found error, when it's really compiler version unknown.

>>> spcall('llvm-gcc -dumpversion')
4.2.1

The split fixes the dumpversion.

Currently on OSX the best thing you can do is forcing a specific compiler with CC=xxx. Personally i always use

CC=clang make

but others users could prefer others compilers

my Mac happens similar error. i find a way fix it.

my Mac env:

• os: osx 10.11.2
• py2: python2.7
  • pip2
  • virtualenv
• py3: python3.4
  • pip3
  • virtualenv

when i install uwsgi, it is really weird. pip2 is OK, but pip3 happens error!

• that is really weird, i do not know, why pip2 is OK, but pip3 is not work!

pip2 install uwsgi   # it is OK !

pip3 install uwsgi   # happens error !

How to fix it? for pip3 (python3.4)

• see here. stackoverflow
• use below cmd, it works for me.

# use this command. it works for me.
CC=gcc pip3 install uwsgi
