What can I do to get sage not to compile numpy?

[Al Kelley]

Using dnf to install sagemath works on Fedora 34,  but then /usr/bin/sage gives

a weird error message.  Compiling sage from sage-9.2.tar.gz does not work.

Using CC=clang CXX=clang++ FC=flang it hangs.  Here are the last three

lines that get printed to the screen:

[numpy-1.19.5] creating build/src.linux-x86_64-3.9/numpy

[numpy-1.19.5] creating build/src.linux-x86_64-3.9/numpy/distutils

[numpy-1.19.5] building library "npymath" sources

What can I do to get sage not to compile numpy?

Sage seems to be happy with my python3.

Why does it not like my numpy?

This is what I have installed:

           boost-numpy3.x86_64    1.75.0-4.fc34  @fedora

          python3-numpy.x86_64  1:1.20.1-1.fc34  @fedora

     python3-numpy-f2py.x86_64  1:1.20.1-1.fc34  @fedora

      python3-numpy-stl.x86_64    2.11.2-3.fc34  @fedora

Please report Fedora packaging bugs to Fedora.

This is much too little information. We need at least the top-level config.log, and the full build log of the package.

In any case, 9.2 is outdated, but also 9.3 does not support building on Fedora 34 with the default compilers.

You can try the branch at https://trac.sagemath.org/ticket/31786

This is not supported by the Sage distribution.

install gfortran and do not set FC

(or set FC=gfortran)

I am not aware of successful attempts to

build Sage using flang
