Hi Nathan,

I don't see the error you're referring to in the log file you attached.

Can you paste the full install log into an unlimited pastebin ( gist.github.com or pastebin.com) and send us the link?

Cheers,

Nathan Goldbaum

This is one of the harder things to get around with the SciPy install, which is getting a working shared/static setup that can be linked against by SciPy; in fact, it's one of the reasons that we stopped doing scipy by default.

-fPIC is a compiler optimization, only available to statically linked libraries (which Python by default does not use) that improves portability -- essentially, when running a function from a library, you end up in a situation where the position of the code in memory does not govern how it executes. More info can be found here:

http://en.wikipedia.org/wiki/Position-independent_code

The reason this is done is that if the code is not position independent, you can optimize it slightly further than if it needs to retain information about its relative position.

Regardless, the solution tends to be to build your own BLAS/ATLAS/LAPACK stack, or disabling them during the build of SciPy. If you are doing a large amount of linear algebra, you probably want to be careful about how you choose to do this. But, if you're not, you can probably even get away with installing SciPy from source and disabling them, like so:

ATLAS=None BLAS=None LAPACK=None python2.7 setup.py install

which will build workalike libraries inside scipy rather than using the system ones. But, again, this may not be right for your use case.

Best of luck,

Hello all,

I have tried to install SciPy with pip after installing yt without SciPy and encountered what appears to be the same error judging by the last few lines of the output from pip. In addition, I got an error from pip that states:

-- Command /mnt/home/butche44/yt-x86_64/bin/python2.7 -c "import setuptools, tokenize;__file__='/tmp/pip_build_butche44/scipy/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-QstpeJ-record/install-record.txt --single-version-externally-managed --compile failed with error code 1 in /tmp/pip_build_butche44/scipy

I have set the BLAS and LAPACK environment variables but have done nothing with ATLAS so I will look into that next.
