pythonqt uses the qmake build system which I am not very familiar with, however the issue seems to be deriving from that file [0] [0] This is due to https://sourceforge.net/p/pythonqt/code/HEAD/tree/trunk/build/python.prf This line: unix:LIBS += $$system(python$${PYTHON_VERSION}-config --ldflags) will need to be changed to unix:LIBS += $$system(python$${PYTHON_VERSION}-config --libs --embed) for 3.8 The default python version is changing dynamically according to the SPEC: https://src.fedoraproject.org/rpms/pythonqt/blob/master/f/pythonqt.spec#_47 A conditional ideally should be added there so if the python version is 3.8 or higher then the embed option is added, however I didn't find a good way to do that in the code (unless just hacking the SPEC to apply a patch conditionally). Igor any ideas? build/python.prf should be modified to use the new --embed flag: https://docs.python.org/dev/whatsnew/3.8.html#debug-build-uses-the-same-abi-as-release-build unix:LIBS += $$system(python$${PYTHON_VERSION}-config --ldflags) unix:QMAKE_CXXFLAGS += $$system(python$${PYTHON_VERSION}-config --includes) I tried to use bash syntax to run a second if the first one fails: unix:LIBS += $$system(python$${PYTHON_VERSION}-config --ldflags --embed || python$${PYTHON_VERSION}-config --ldflags) unix:QMAKE_CXXFLAGS += $$system(python$${PYTHON_VERSION}-config --includes --embed || python$${PYTHON_VERSION}-config --includes) Problem: qmake syntax doesn't accept "||", it has a different meaning. A bash script could be added to use shell syntax, and build/python.prf would run this script using $$(system). Igor? Retired. |
