During the build_ext step of an installation of badic I am facing the following relatively strange error

Works for me. But I noticed many changes to badic after you posted this, so maybe it got fixed upstream.

videlec commented 5 years ago

It got "fixed" but I have no idea why. The setup.py was somewhat messed up but I do not explain myself why we got such an error from gcc.

jdemeyer commented 5 years ago

If you remember the badic commit that you built from, I could have a look.

tobiasdiez commented 3 years ago

I encounter the same problem in https://trac.sagemath.org/ticket/30371 (in src/setup.py uncomment the lines following # TODO: Fails due to problem in cysignals (missing cysigs) to trigger this error when running pipenv install).
