MINSIGSTKSZ is no longer a constant, which causes this problem.

Does it compile, when you add `--std=c11` to your `CFLAGS`.

E.g. do `sage -sh` and then `echo $CFLAGS` and then

run

make cysignals CFLAGS="<whatever you saw> --std=c11"

Sorry for the wrong reference, I guess the following reference is better:

Maybe compiling cysignals without march native is also and option until this problem is resolved for cysignals.

Unfortunatelly it doesn't compile, exact same error

Being this an error caused by a change in glibc 2.34 I don't think there is much

to do whilst we wait for the cysignals fix, but I may be wrong,.

so any other idea is welcome

Thanks

Manuel

I have have found a fix elsewhere and copy/pasted it in https://github.com/sagemath/cysignals/pull/151, this might already solve the issue.
