Throwing this out there.. woes with Python 3.2 sysconfig and more..
I recently started migrating a Pyramid app to py3.2 and hit a uWSGI build issue
with the python installer;
sysconfig.get_config_var returns 'gcc-4.2', which doesn't exist on my system,
but py2.7 reports 'llvm-gcc-4.2' correctly.
I got uwsgi to compile by setting env 'CC=gcc', causing the installer to avoid
sysconfig and use the os.environ.get value instead.
Then hit another error; Pip error info didn't help me much, but easy_install
reports 'ld: library not found for -lpython3.2m'. lpython3.2m doesn't exist but
python3.2m does.
I can see there is a problem with the Py3.2 sysconfig and not the uwsgi
installer, but I'm scratching my head to diagnose the second error and wonder
if it's symptomatic of the first?
I suspect an Apple/Darwin issue with Python3 ..anyone seem similar problems?
Best, S
Transcript below:
### Py3.2 - Install via pip - mis-reports gcc as ``gcc-4.2``. Installer gets
'None' for dumpversion because it doesn't exist.
Traceback (most recent call last):
File "uwsgiconfig.py", line 304, in __init__
gcc_major = int(gcc_version.split('.')[0])
ValueError: invalid literal for int() with base 10: 'None'
