Description
After #657 was merged, I tried to build the TEM in a docker container (based on debian:trixie-20250520, Python 3.13) using
meson 1.8.1
ninja 1.11.1.4
numpy 2.2.6
packaging 25.0
pip 25.1.1
wheel 0.46.1
During compilation we see this warning
3.019 [5/5] Linking target total_energy.cpython-313-x86_64-linux-gnu.so
3.019 /usr/bin/ld: warning: efermig.o: requires executable stack (because the .note.GNU-stack section is executable
and then this seemingly related error when importing
3.098 + python3 -c 'import total_energy'
3.111 Traceback (most recent call last):
3.112 File "<string>", line 1, in <module>
3.112 import total_energy
3.112 ImportError: /opt/soft/git/mala/external_modules/total_energy_module/total_energy.cpython-313-x86_64-linux-gnu.so: cannot enable executable stack as shared object requires: Invalid argument
A quick search shows that one can solve that using ld -z noexecstack, and indeed adding this to LDFLAGS removes the warning and the import works.
I have not yet tested this TEM in production, so I can't say whether this fix has side effects.
