Hi all,

I have troube installing numpy in a virtual environment on a SuSE
Enterprise 11 server (ppc64).

Here is what I did:

curl -O https://raw.github.com/pypa/virtualenv/master/virtualenv.py
python virtualenv.py --distribute --no-site-packages .virtualenvs/pydoas
source .virtualenvs/pydoas/bin/activate
pip install numpy

And here is the outcome:

SystemError: Cannot compile 'Python.h'. Perhaps you need to install
python-dev|python-devel.

However, Python.h exists, because I did install the python-devel package:

(pydoas)hilboll@odin:~/.virtualenvs/pydoas/build/numpy> find
/usr/include/ | grep Python.h
/usr/include/python2.6/Python.h

I also tried without the --distribute --no-site-packages flags, with the
same result.

Any hints are very welcome :)

Cheers,
Andreas.

Hard to say what's going wrong. Perhaps pip is not for python2.6 but another python version? Can you install without pip, so normal "python setup.py install"? Can you post the full build log?

Thanks for your ideas, Ralf! Actually, it turned out to be a problem with
the gcc installation on the machine I was building on. The sysadmin fixed
that, and now NumPy is running fine :)

Cheers,
A.
