debian package of numpy for debian wheezy with py2deb

[emilio-molina]

Hi, thanks for py2deb, it's exactly what I need now.

I'm trying to create a debian package of numpy for debian wheezy for the version v1.14.1 (the official debian package is an older version). However, I'm having these errors:

# py2deb -r /output_debs/ numpy

BuildFailed: Failed to build numpy (1.14.1) binary distribution!

Please check the build output because it will probably provide a hint about what went wrong.

Build output:

Running from numpy source directory.
`setup.py bdist` is not supported
Add `--force` to your command to use it anyway if you must (unsupported).

Any advice?
Thanks.

The setup.py file for numpy doesn't allow the bdist installation method, my solution is to patch setup.py (it requires modifying two lines), see: numpy/numpy#7632
The change to setup.py:
ddboline/numpy@c5435d0

[vidstige]

There seens to be a --force option. Can we use this somehow? Perhaps have a hueristic that py2deb passes --force if doing numpy? Perhaps this can be handled in a module for special tweaks for tricky/non-standard packages?

@ddboline Could you elaborate more how to tweak it, I am facing the same issue on production right now and I cannot get a debian package out of numpy....
