Context
I'm trying to build PyQt bindings and I'm following the example in https://github.com/lxqt/qtermwidget/blob/master/.ci/build.sh. I have already built and installed all the needed dependencies.
System Information
- Distribution & Version: Mac OS 12.6.1
- Kernel: Mac OS
- Qt Version: 6.3.2 (but I also have qt5 installed)
- lxqt-build-tools Version: 0.11.0
- Package version: I'm not sure what is this asking for exactly
Qt Version: 6.3.2
QTermWidget does not support Qt 6 yet. Most likely you need to tell sip-wheel to use Qt 5.
How do I tell sip-wheel to use Qt 5?
Specifying the path to qmake from Qt 5 should work. For example,
sip-wheel --verbose --qmake /usr/bin/qmake-qt5
I did
CXXFLAGS="-I$PWD/../lib -I$PWD/../build/lib" LDFLAGS="-L$PWD/../build" sip-wheel --verbose --qmake /usr/local/lib/python3.10/site-packages/qt5_applications/Qt/bin/qmake
and got

On my machine (Arch Linux), the qmake spec 'macx-clang' is in /usr/lib/qt/mkspecs/macx-clang. Not sure if something goes wrong for Qt on macOS - I no longer have macOS for testing, anyway.
By the way, the path /usr/local/lib/python3.10/site-packages/qt5_applications/Qt/bin/qmake does not seem a standard Qt installation. qmake is part of C/C++ Qt and is generally unrelated to Python.
