Description Rik Mills 2019-12-11 11:32:28 UTC 
SUMMARY

Debian unstable and Ubuntu 20.04 proposed repo have a build of boost where python2 build/support is dropped.

kig then fails to find BoostPython on configure, even though pythonboost is correctly installed.

In the stable release repos where boost has python2 support and the pythonboost meta package pulls in python2 and python3, boost is found with the message:

Found BoostPython: /usr/lib/x86_64-linux-gnu/libpython2.7.so;/usr/lib/x86_64-linux-gnu/libboost_python.so
Comment 1 David E. Narvaez 2020-01-01 14:52:50 UTC 
If I understand correctly you are reporting that BoostPython is not found when all you have is Python 3, right? If that is the case, I believe it is by design since the Python scripting interface has not been adapted to Python 3. This should happen now because of the Python 2 EOL.
Comment 2 Christoph Feck 2020-01-01 19:57:03 UTC 
Not sure if there is more Python usage in Kig, but pykig was recently ported to Python3, see https://phabricator.kde.org/D25982

There is.

Right, and I believe the reporter may think this meant Kig now supports Python 3.
Comment 4 Rik Mills 2020-01-01 20:15:32 UTC 
No, it was this commit in the scripting dir that must have made me think it was or should supported.

https://cgit.kde.org/kig.git/commit/scripting?h=release/19.12&id=c0aa768f28219ce8b3c275a6d13ad69757e3c7af

"Try to fix Python 3 build"

Especially as that scripting dir only included by

if(BoostPython_FOUND)
  add_subdirectory( scripting )
  add_definitions(-DKIG_ENABLE_PYTHON_SCRIPTING)
endif(BoostPython_FOUND)
