Error trying to build psutil from source with mingwpy-0.1.0b3

[ogrisel]

Here is the build message I got trying to build the latest release tag release-3.4.2 of the https://github.com/giampaolo/psutil repo:

There are many more errors after that. Here is the full log: https://gist.githubusercontent.com/ogrisel/e08d59f9c8ac500855bc/raw/6c539599c759583508f6d1b2c3f9e7e4395630da/psutil-build.log

Environment:

• Windows 10 (64 bit)
• Python 3.4.4 or Python 2.7.11 (64 bit)

Note that the problem was already present in 0.1.0b1.

BTW @carlkl I think you should create the mingwpy main repo ASAP so that we can put such bug reports on the mingwpy issue tracker instead of the mingwpy.github.io issue tracker that should be dedicated to the website and the documentation of the project instead.

[ogrisel]

I can also reproduce those errors with my version of mingwpy-dev's gcc compiled from source.

[carlkl]

@ogrisel, is it giampaolo/psutil#345 (comment)?

[carlkl]

@ogrisel, I still get build errors with my local mingw-builds variant I have to figure out. This may take some more time as expected due to the long build times and the number combinations of setings I have to try out. Nevertheless I will create an empty repo for the wheel-builder.

The original patch to get psutils working on mingw is attached to giampaolo/psutil#158

The main author of psutil has also been planning to remove mingw32 code, on the basis it isn't working any more, and the code is messy, so it might be good to get this working soon: giampaolo/psutil#591

[ogrisel]

Ok indeed. psutil is not a good test project for mingwpy then.

FYI I built scikit-learn and all tests pass. Cython seems clean too although I did not run the test suite yet. pandas is almost clean.

It could be interesting to try to build libxml2 / libxslt and lxml with mingwpy but that sounds more complicated. And maybe database connectors for postgresql and mysql, Pillow and pyzmq.

But the real deal is numpy & scipy + openblas as AFAIK those are the only projects that really need gfortran :)

[ogrisel]

Let me close this issue then.
