Error building sage: cython-0.29.36 will not build

[David Ayotte]

Hello everyone,

I just pulled the last development version (10.2.beta3) and somehow SageMath won't build now. The building process stops at Cython. It would be greatly appreciated if anybody can help. I attached the log files to this message.

My operating system is Ubuntu 22.04.3 LTS under WSL (Windows 11).

Thank you very much in advance,

David Ayotte

Quick update: I tried rebuilding SageMath after doing a "make distclean", and now the compilation goes further, but stops at SciPy. The error says:

    ModuleNotFoundError: No module named 'mesonpy'

I attached the logs for a longer traceback.

Thanks,

David A.

We need

+++ b/build/make/Makefile.in
@@ -325,7 +325,7 @@ all-toolchain: base-toolchain

As a temporary workaround, run

make meson_python

and then run

make
