QTermWidget PyQt6 bindings fail with error - qtermwidget.sip:14:10: fatal error: qtermwidget.h: No such file or directory

[nado218]

Hi, I'm new to pyQT and I'm trying to build python bindings for QTermWidget. I could compile and install qtermwidget library but when I try to create a python wheel using sip-wheel --verbose, i get the below error. What I'm I missing here. My QTermWidget is installed in installed to the default - /usr/local/

I see the same error with QT5 as well. I'm sure i'm missing something here.

Below is the log.

Below is my build environment

QTermWidget Package version: 2.0.1
Distribution & Version: Ubuntu 22.04
Kernel: 6.5.0-44-generic
Qt Version: PyQt6 - 
 PyQt6==6.7.1
 PyQt6-Qt6==6.7.2
 PyQt6_sip==13.8.0
lxqt-build-tools Version: 2.0.0 (Compiled from source and installed to /usr/local).
QTBase :  6.6.0 (Compiled from source and installed to /usr/local) 
qttools :   6.6.0 (Compiled from source and installed to /usr/local)
pyqt-builder : 1.16.4 (Installed using pip3)

Is it possible to install QTermWidget using apt-install on Ubuntu linux ? can qtermwidget be used with python on Ubuntu Linux. If yes, can you please suggest how to overcome this error during sip-wheel ?

Any help would be very much appreciated.

Thank you.

Hi Can anyone please suggest how to proceed.

I guess this may be about a simple mistake in compilation. But since I have no knowledge of this part of the code, I ask @yan12125.

@yan12125, could you please take a quick look?

[yan12125]

Most likely the issue is that somehow -I/usr/local/include/qtermwidget6/ is specified in CXXFLAGS but not used by sip-wheel. No idea why that happens, though.

Has anyone use python qtermwidget on linux

[yan12125]

I did basic testing of python qtermwidget from time to time on Arch Linux. @tsimonq2 may know more about Ubuntu.

[cemelo]

If you replace <qtermwidget.h> by <qtermwidget6/qtermwidget.h> in the .sip file it works.

[tsujan]

Thanks!

@yan12125, should we replace <qtermwidget.h> with <qtermwidget6/qtermwidget.h>, as suggested by @cemelo?

[yan12125]

@yan12125, should we replace <qtermwidget.h> with <qtermwidget6/qtermwidget.h>, as suggested by @cemelo?

I'd like to check what's going on before moving on. It's a little bit strange that <qtermwidget.h> fails and <qtermwidget6/qtermwidget.h> works. qtermwidget.h further includes several other header files in the qtermwidget6 folder (Emulation.h, Filter.h, etc.), so the qtermwidget6 folder should already be in the include path. @cemelo Mind to share your complete build logs?

[tsujan]

@yan12125 Although I've read and made fixes to almost every part of qtermwidget since I started to maintain it, this part is an exception because of my poor knowledge of Python. So, please attend to it whenever you find the time.

[yan12125]

Sure.

For this specific issue, the issue is more related to the C++, as the following line is copied as-is when a .cpp file is generated from the sip file. Hence, I asked for complete build log. https://github.com/lxqt/qtermwidget/blob/c3f6de38b1856b3b385933d3b4fae53de23ad39b/pyqt/sip/qtermwidget.sip#L14

error: qtermwidget.h: No such file or directory

i fixed this by setting include-dirs in the tool.sip.bindings.name section of pyproject.toml in qtermwidget.nix

cat >>pyproject.toml <<'EOF'
[tool.sip.project]
