cython 3.0.11 breaks building sagemath-standard

[kiwifb]

As the title says. The final error is reminiscent of #783 but in the end quite different in its causes.

this works perfectly with cython 3.0.10.

[kiwifb]

Similar cython errors show up in sage/matroids/flats_matroid.pyx, sage/matroids/matroid.pyx, sage/matroids/union_matroid.pyx, sage/matroids/graphic_matroid.pyx, sage/matroids/linear_matroid.pyx and sage/sets/disjoint_set.pyx

[kiwifb]

And sage/matroids/basis_exchange_matroid.pyx. I cannot exclude missing a few others.

[strogdon]

sage with cython-3.0.11 and the regression patch void-linux/void-packages@b5926bd does build. However, the regression patch does not appear under https://github.com/cython/cython/commits/master/

[kiwifb]

I have a patch in the vbraun branch and we are working on something a bit better upstream. sage needs to get rid of those things anyway. Fun fact, cypari2 from the main tree is also failing to build with cython 3.0.11 from the tree - 2.2.0 which I am pushing, does not have the problem.

[kiwifb]

OK, my work on getting cython 3.0.11 to work with sage is merged and officially out in the current dev branch. I am experimenting with a new way to distribute patches from upstream PR so once I merge my current development branch sage 10.4 will have support for cython 3.0.11 (you may have to update cypari2 to 2.0.0 as well). The way I distribute the patch is experimental, report issues please
The merge will be done in the next hour.

After a length system update I see:

Perhaps the patch file had been misnamed?

[kiwifb]

Looks like I may have done something stupid, but I should have caught it. Let me check all that.

[kiwifb]

Yes, I try to process the patch somewhere I should not have. I need to update the eclass.

[kiwifb]

OK, I have updated the eclass, it should take about 15mn for the gentoo mirror to update.

[strogdon]

sagemath-standard-9999 now builds but sage-doc-9999 fails.

I'm having the same problem emerging it as in

Should it not be solved already? (reading from the previous replies it seemed like it was already partially solved)

[Etn40ff]

A dirty workaround is to downgrade to cython 3.0.10, install sagemath-standard then update cython again

I am fairly sure that's a different issue. What is your version of scikit-build-core?
