Main.log from PPC Tiger

[evanmiller (Evan Miller)]

Upstream PR: ​https://github.com/numpy/numpy/pull/20422

[ballapete (Peter "Pete" Dyballa)]

Replying to evanmiller: This is a terrible site for my TenFourFox – it lets the fans of my PowerBook G4 run at a deafening noise level. Actually the page where I found your patch. Since for x86_64 and PPC the sizes are equal couldn't they be united as:

    #elif defined(__x86_64) || defined(__ppc__) || defined (__ppc64__)
        #define NPY_SIZEOF_LONGDOUBLE         16
        #define NPY_SIZEOF_COMPLEX_LONGDOUBLE 32

[ballapete (Peter "Pete" Dyballa)]

PPC Leopard, Mac OS X 10.5.8, has the same issue.

[ballapete (Peter "Pete" Dyballa)]

Patch to add PPC and PPC64 support to numpy, based on evanmiller's work

[ballapete (Peter "Pete" Dyballa)]

The build started…

[ballapete (Peter "Pete" Dyballa)]

Wouldn't this also need an update to support PPC and PPC64?

[evanmiller (Evan Miller)]

@ballapete I don't see anything about the snippet that indicates a change is needed for PPC to work. These look like they have to do with enabling extra CPU features.

[ballapete (Peter "Pete" Dyballa)]

py38-numpy @1.21.4_0+gfortran+openblas built and installed. I tried to test it, but obviously failed to run the proper command. I tried ./runtests.py but this seems to have tried a re-build… and failed!

Apparently closed with the ​update of NumPy to 1.22.1. Please reopen if this is still an issue for you and add more info as to what's going on.
