lxqt-build-tools version "0.8.0" required for compilation?

[mcondarelli]

Apparently build instructions are a bit off.
They state:

The only runtime dependency is qtbase ≥ 5.7.1. In order to build CMake ≥ 3.0.2 and lxqt-build-tools >= 0.4.0 are needed as well as Git to pull translations and optionally latest VCS checkouts.

But I get:

See also "/home/mcon/projects/qtermwidget/build/CMakeFiles/CMakeOutput.log".

I am running on a fairly up-to date Linux Mint 20.1 "Ulyssa".
My distribution already has binary distribution for qtermwidget, my only interest in compiling is I need to use this from Python (either PyQt5 or Pyside) and I was not able to find relevant bindings while I understand they should be available recompiling.

Build instructions for Python would be much appreciated.
I could help in preparing a setup.py suitable for general consumption (i.e.: for PyPi)

Thanks In Advance

Update:
I have been able to overcome the above problem by manually lowering requirements in CMaleLists.txt, but I'm far from confident that is a good idea.

I also tried to build the PyQt5 bindings, but I got a bad error (apparently unrelated to the above):

QMetaType is available, of course, as part of the qtbase5-dev package:

But, for some reason, is not found :(

Any hint welcome.
TiA!

Update2:
I managed to have an apparently working version of QTermWidget.

I am uneasy with it thou as I had to compile with:

CPLUS_INCLUDE_PATH='/usr/include/x86_64-linux-gnu/qt5:/usr/include/x86_64-linux-gnu/qt5/QtCore:/usr/include/x86_64-linux-gnu/qt5/QtGui:/usr/include/x86_64-linux-gnu/qt5/QtWidgets:../build:/home/mcon/projects/qtermwidget/build/lib' make

which surely does not look right.

Explicit build instructions would be most welcome.
I will not venture in building for pyside2/pyside6 without some directions.

Thanks.

lxqt-build-tools version "0.8.0" required for compilation?

I have been able to overcome the above problem by manually lowering requirements in CMaleLists.txt, but I'm far from confident that is a good idea.

Yes, qtermwidget targets only the latest version of lxqt-build-tools. Older version may work but not recommended.

Build instructions for Python would be much appreciated.

Currently PyQt bindings should be built together with the main library using the cmake option QTERMWIDGET_BUILD_PYTHON_BINDING=ON. Our CI script for Arch Linux may help https://github.com/lxqt/qtermwidget/blob/master/.ci/build.sh

I could help in preparing a setup.py suitable for general consumption (i.e.: for PyPi)

That is much appreciated! Leave a comment at #364 is you have anything to discuss/share/etc.

I also tried to build the PyQt5 bindings, but I got a bad error (apparently unrelated to the above):

I am uneasy with it thou as I had to compile with:

Thanks for testing. Include paths should be correctly set with QTERMWIDGET_BUILD_PYTHON_BINDING=ON

I will not venture in building for pyside2/pyside6 without some directions.

Currently only there are only PyQt bindings. PySide2 is requested (#249) while not solved.
