Pyinstaller --onefile warning pyconfig.h when importing scipy or scipy.signal

Question

This is very simple to recreate. If my script foo.py is:

import scipy

Then run:

python pyinstaller.py --onefile foo.py
         


        

Answer 1

I realized that the problem is that Windows is case-insensitive and these 2 statements are source directories are "duplicates: include\pyconfig.h Include\pyconfig.h

My solution is to manually tweak the .spec file with after the a=Analysis() call:

import platform
if platform.system().find("Windows")>= 0:
    a.datas = [i for i in a.datas if i[0].find('Include') < 0]

This worked in my 2 tests.

A more flexible solution would be to check ALL items for case-insensitive collisions.
