Hi, I'm trying to build the python bindings for QScintilla v2.12.1 from source on Linux and facing several issues. I'm using sip 6.1.1, PyQt-builder 1.10.1, Qt 5.15.2, PyQt 5.15.4. I already compiled the QScintilla C++ library against Qt 5 and installed it system-wide.
1/ The first issue is that sip-build cannot find QtCoremod.sip out-of-the-box. $ sip-build --no-make --verbose Querying qmake about your Qt installation... /usr/bin/qmake -query These bindings will be built: Qsci. Generating the Qsci bindings... sip-build: Unable to find file "QtCore/QtCoremod.sip" I was able to fix this by adding the following two lines to pyproject.toml: [tool.sip.project] sip-include-dirs = ["/usr/share/sip/PyQt5"] However, it seems odd that I have to edit pyproject.toml. Isn't there a default system-wide search path for the .sip files? If so, shouldn't PyQt5 install the files there for a better out-of-the-box experience? Or maybe the QScintilla package should include the two lines above? Either way, a command line option to specify the sip include dir would feel a little less awkward than editing the pyproject.toml file. 2/ After "fixing" the previous issue, sip-build still fails: $ sip-build --no-make --verbose Querying qmake about your Qt installation... /usr/bin/qmake -query Checking to see if the Qsci bindings can be built... /usr/bin/qmake Qsci.pro Info: creating stash file /tmp/portage/dev-python/qscintilla-python-2.12.1/work/QScintilla_src-2.12.1/Python/build/cfgtest_Qsci/.qmake.stash make g++ -c -pipe -O2 -Wall -Wextra -D_REENTRANT -fPIC -DQSCINTILLA_DLL -DQT_NO_DEBUG -DQT_PRINTSUPPORT_LIB -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I. -I/usr/include/qt5 -I/usr/include/qt5/QtPrintSupport -I/usr/include/qt5/QtWidgets -I/usr/include/qt5/QtGui -I/usr/include/qt5/QtCore -I. -I/usr/include/libdrm -I/usr/lib64/qt5/mkspecs/linux-g++ -o cfgtest_Qsci.o ../../config-tests/cfgtest_Qsci.cpp g++ -Wl,-O1 -o Qsci cfgtest_Qsci.o -L/usr/lib64 -lqscintilla2_qt5 /usr/lib64/libQt5PrintSupport.so /usr/lib64/libQt5Widgets.so /usr/lib64/libQt5Gui.so /usr/lib64/libQt5Core.so -lGL -lpthread /tmp/portage/dev-python/qscintilla-python-2.12.1/work/QScintilla_src-2.12.1/Python/build/cfgtest_Qsci/./Qsci /tmp/portage/dev-python/qscintilla-python-2.12.1/work/QScintilla_src-2.12.1/Python/build/cfgtest_Qsci/cfgtest_Qsci.out These bindings will be built: Qsci. Generating the Qsci bindings... sip-build: Q_PID is undefined This is where I'm stuck now and honestly I'm not sure how to debug this. 3/ This is merely a suggestion. The error messages from sip-build are not particularly user friendly. In fact, at first it wasn't clear to me that "Q_PID is undefined" was a fatal error at all... I only realized that later when I couldn't find the generated Makefile. Also I suppose it could be useful to print the path of the file being processed when an error is encountered, or the location (file+line) of the undefined reference (to Q_PID in this case). Again, just a suggestion. Thanks, Davide
