[doc] please switch du sphinx with python3

[picca]

Hello, it would be nice to switch from sphinx (python2) to sphinx python3 in order to use a less deprecated python version.

thanks

I don't understand how this is affected by our code and not the build environment? Isn't Sphinx picking up whatever Python interpreter is currently installed? The only thing I do is looking for a sphinx-build script.

sorry matthias, I was updating the Debina package and needed to switch from python2 to python3.
It is trivial for the documentation :) python3-sphinx

now there is some code like the ufod and I would like to know how if it is python3 ready ? so I just need to switch from pyton-dev to python3-dev

Yes, that's what I mean, that's a build environment thing not something I could influence. The only Python piece we provide for the manual is conf.py and that looks sane to me.

ufod is C. The only offenders are ufo-mkfilter and ufo-prof, and seem to be okay. But I can check tomorrow morning.

I can confirm that ufo-launch is linked against libpython2.7, So It would be nice if we should link against the python3 version. Maybe to add a compile option in ordert to use python2 instead of the default python3 ;)

No I miss read the build log.

here the log

so I need some rest ;)

I just rebuild all the packages with --as-needed and I end up with a libufo package which depends on libpython2.7

[matze]

I just pushed a reversion of an old commit. Now, libufo.so should only link against the Python development libs you set as the default. I will try to disentangle the build flags for the binaries from the lib itself (one more reason for meson ... ;-) )
