Unable to build extension in python 3.5 #455

Closed ghost closed 8 years ago

ghost commented 8 years ago

Originally reported by: kracekumar (Bitbucket: kracekumar, GitHub: kracekumar)

I am using OSX 10.10.5 (14F27) and Python 3.5. Python 3.5 was installed via brew. When greenlet is installed inside virtualenv using py3.5 header files are missing inside /path/to/venv/include/python3.5m. As a result uwsgi is unable to build with asyncio support

Also setuptools is at latest version 18.2.

Installing uwsgi site wide succeeds. greenlet directory is present inside python3.5m.

Already reported the bug in uwsgi https://github.com/unbit/uwsgi/issues/1100.

Also I typed correctly (CC=clang). Once again I tried and following is the output.

Original comment by jaraco (Bitbucket: jaraco, GitHub: jaraco):

@kracekumar I'm slightly surprised that it's not working for you with easy_install. Are you sure you typed it correctly? You mistyped it in your message above. It should be CC=clang not cc=CLANG.

I don't believe the issue lies with distutils; it may lie with Python itself. But before you file a ticket with Python, I recommend you either file a ticket with uwsgi, which I see may not be possible, because the issue seems to be unique to their implementation (and around for some time). If you can't file a ticket with uwsgi, then I recommend you download the source and debug building it yourself or reach out on their support forums for help there.

Best of luck -Jason

Should I report the bug to distutils https://bitbucket.org/carljm/python-distutils ?

Thanks Jason. Building extension via easy_install results in same error and setting cc=CLANG also doesn't help in pip.

Exception: you need a C compiler to build uWSGI

Looking at the AttributeError, it seems that gcc_version is None at 692:

$ curl https://pypi.python.org/packages/source/u/uWSGI/uwsgi-2.0.11.2.tar.gz#md5=1f02dcbee7f6f61de4b1fd68350cf16f -o - | tar xz

   692              gcc_version_components = gcc_version.split('.')

And that value is set here:

$ nl -b a uwsgi-2.0.11.2/uwsgiconfig.py | sed -n '651,657p'
   651          gcc_version = spcall("%s -dumpversion" % GCC)
   652          if not gcc_version and GCC.startswith('gcc'):
   653              if uwsgi_os == 'Darwin':
   654                  GCC = 'llvm-' + GCC
   655              else:
   656                  GCC = 'gcc'
   657              gcc_version = spcall("%s -dumpversion" % GCC)

Tracing into that code, I find

$ python -m pdb setup.py build_ext
> /Users/jaraco/uwsgi-2.0.11.2/setup.py(1)<module>()
-> import os
(Pdb) b uwsgiconfig.py:651

-> gcc_version = spcall("%s -dumpversion" % GCC)
(Pdb) GCC
'gcc-4.2'

And indeed, that command does not exist on my system:

$ gcc-4.2
-bash: gcc-4.2: command not found

And that GCC variable seems to be set here:

$ nl -b a uwsgiconfig.py | sed -n '23,30p'
    23  from distutils import sysconfig
    24  
    25  try:
    26      import ConfigParser
    27  except:
    28      import configparser as ConfigParser
    29  
    30  GCC = os.environ.get('CC', sysconfig.get_config_var('CC'))
$ python -c "import sysconfig; print(sysconfig.get_config_var('CC'))"
gcc-4.2

So, although sysconfig.get_config_var('CC') returns gcc-4.2, there's no gcc-4.2 on the system. However, using the environment variable override indicated by line 30 seems to work:

$ CC=gcc python -m easy_install uwsgi

Seems you're not the only one who's encountered this issue. The reply at the bottom indicates that this issue stems from a long-deprecated expectation of "gcc-4.2". I suspect that this value stems from the public releases of Python being built on older OS X clients for compatibility.

I'll bet setting CC=clang when installing uwsgi is the best workaround.

There's no defect in setuptools here. There may be a defect in Python or distutils, but building normal C extensions on setuptools works just fine.

Updating the wheel version fixes the assertion whereas building uwsgi still fails.
