Re: Why can't I see/use plugins in www/liferea?



I managed to build libpeas with python3 support, entirely manually
fighting with ninja. My default python is still 3.7 and I have only
python-3.7.pc; for some reason neither python was found during the
config stage and the necessary include files, libraries and .pc files
linked under .buildlink; I added them manually; examining the meson
output, I found it was looking for python3.pc and python3-embed.pc ; I
copied python-3.7.pc to python3.pc in the pkgconfig directory and
created python3-embed.pc (modified python-3.8-embed.pc as there was no
python-3.7-embed.pc at all). After that meson found the embedded
python3.7 and managed to build libpython3loader.so, but the latter was
not linked to libpython3.7.so; I ran the ninja command with -v, caught
the output and added '-lpython3.7'; the resulting libpython3loader.so
works fine - with both gedit and liferea.

Overall a bit of an exercise for the package maintainer - I am not
sure how to approach the meson/ninja stuff with respect to paching the
process. But there is no reason not to enable this, I guess.

Screenshot attached.
