Build fails with some boost-python error on Manjaro

[leberknecht]

Hi, I hope that this is the right place :) => im trying to update from 17.2.6-2 to 17.2.6-3 and im getting this:

  but it set boost_python_FOUND to FALSE so package "boost_python" is
  considered to be NOT FOUND.  Reason given by package:

same happens when im trying latest 17.2.6-3 from source:

Any ideas how to solve this?

Maybe its related to the fact that i have python 3.9 and 3.11 installed, looks like the boost libs exist only for 3.11 I see that there is a cmake flag Boost_PYTHON_VERSION which i could point to 3.11 maybe, but im not sure how/where to set this flag. I tried to export it as env-variable, but that didnt helped

[leberknecht]

i edited /usr/lib/cmake/boost_python-1.81.0/boost_python-config.cmake and hardcoded

set(Boost_PYTHON_VERSION "3.11")

and that actually seems to work, build is running now :)

Closing this, doesnt seem to be a problem with this package. Sorry!
