sagemath_doc_html does not build

[enriqu...@gmail.com]

In fedora 43 and some machines, this package does not build. I attach the log, it must be something local to it but I am not able to see what. Best, Enrique.

This happens if you build using a non-english locale. These warnings are whitelisted in https://github.com/sagemath/sage/blob/10.8/src/sage_docbuild/sphinxbuild.py#L104-105, but only in their English version, not the localized one. I guess sage_docbuild should set LANG=C before running sphinx (this is done in https://github.com/sagemath/sage/blob/10.8/src/bin/sage#L986 for the doc build via the sage bash script, but that doesn't affect meson).

Gracias/thanks, Antonio. I do not see a difference with other machine where it works. Doing LANG=C make doc does not help.

perhaps it should be

LC_ALL=C

It does not work either. It must be something I changed in this particular laptop. Having documentation is useful, also because when incremental builds it detects wrong system libraries being used. I will try to check with meson build instead make. Thanks any way, Enrique.

Thanks for the tips. Passing LC_ALL=C (and any other like LANG or LANGUAGE) in the terminal where I built sage was OK but only after a make maintainer-clean. Would it be possible with a less radical clean?

make sage-distro-clean and then make doc is enough
