Consumers failing to build with v1.12.0

[orlitzky]

We just added v1.12.0 in Gentoo and switched the build to meson but now the packages that depend on it are failing to build: fpylll, primecountpy, cypari, pplpy, etc.

A typical error:

2024-11-22 07:13:20,452 root INFO building 'fpylll.fplll.wrapper' extension

I tried to debug for a few minutes tonight but it will probably have to wait until next week.

Actually, already compiling the basic example with cythonize -i FILE.pyx gives me those errors (cython version 3.0.11).

It seems that the meson build system doesn't put #include "macros.h" after the late_includes /* #### Code section: late_includes ### */.

Caused by the removal of the line # cython: preliminary_late_includes_cy28=True from signals.pxd in fa6d45d
