SUMMARY As the summary says, the Python support in kig is disabled when only Python 3 is installed, because it is not found by its own FindBoostPython macro. STEPS TO REPRODUCE 1. Have a system with no boost-python for Python 2, but with boost-python for Python 3 installed 2. Run CMake in a checkout of the sources OBSERVED RESULT boost-python is not found and the Python bindings are disabled. EXPECTED RESULT boost-python is found and the Python bindings are enabled. SOFTWARE/OS VERSIONS KDE Frameworks Version: master Qt Version: 5.14
It is found if you build it *without* -DBoost_NO_BOOST_CMAKE=ON. But it needs a recent boost (1.70 I think).
Git commit 1fdeff25f5f113f4567ab100da9df3f0f24c3ce8 by Pino Toscano. Committed on 03/05/2020 at 08:08. Pushed by pino into branch 'master'. cmake: switch python & boost-python search to py3 Python 2 is EOL now, and Python 3 has been available in distros for years already, so it is time to switch exclusively to Python 3. The actual changes to the BoostPython module are: - look for the python3 boost component (instead of python): while boost upstream does not provide it, most of the distros do; the alternative would be to look for the pythonXY components, which is not ideal... - look for the python libraries >= 3, setting as additional versions for the cmake module all the non-EOL Python 3 versions - set as Python versions for pkg-config all the non-EOL ones, using the embed version starting from Python 3.8 [1] [1] https://bugs.python.org/issue36721 FIXED-IN: 20.07.80 M +11 -9 cmake/modules/FindBoostPython.cmake https://commits.kde.org/kig/1fdeff25f5f113f4567ab100da9df3f0f24c3ce8
