Hi Mauro! I noticed two small oddities with sphinx-pre-install I wanted
to quickly tell your about:
(1) running "./scripts/sphinx-pre-install --no-virtualenv" always tells
me to run "sudo dnf install -y python3-sphinx
", even if it's already installed on the system. On a quick look that
seems to happen due to line 738 (on docs-next), that afaics always does...
> add_package("python-sphinx", 0);
...when running with "--no-virtualenv". Doesn't matter too much, but I
thought I mentioned it while reporting the issue that made me write this
mail:
(2) when running 'make htmldocs' I saw this warning:
> WARNING: dvipng command 'dvipng' cannot be run (needed for math display), check the imgmath_dvipng setting
I had run "sphinx-pre-install --no-virtualenv" earlier to get everything
I needed, but it had not told me to install dvipng. So it might be wise
to fix this with a patch like the one below. Please let me know if
that's the right approach, that I submit it as proper patch.
Ciao, Thorsten
