Package: python3-pyside2.qtgui
Version: 5.15.8-2+b1
Severity: normal

Dear Maintainer,
When libqt5gui5-gles is installed (required on arm64 platforms without
desktop OpenGL)
package installation fails with
python3-pyside2.qtgui : Depends: libqt5gui5 (>= 5.15) but it is
not installable
The problem is that python3-pyside2.qt has in its dependencies
libqt5gui5 (>= 5.15), libqt5gui5 (>= 5.15.1) | libqt5gui5-gles (>= 5.15.1)
IE an unconditional dependency on libqt5gui5 and an alternative on
libqt5gui5 or libqt5gui5-gles
I tried (as a hack) to modify the binary package(by unpacking and
repacking it) to
remove the unconditional dependency on libqt5gui5. That makes it installable
but it is still trying to use desktop opengl symbols:
>>> from PySide2 import QtGui
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError:
/usr/lib/python3/dist-packages/PySide2/QtGui.cpython-311-aarch64-linux-gnu.so:
undefined symbol: _ZTI18QOpenGLTimeMonitor, version Qt_5
I've looked at the package source and it seems it is supposed to handle this
by the patch debian/patches/Fix-GLES-builds.patch.
But that removes expected symbols based on QT.gui.enabled_features
The features are supplied by the qtbase5-dev package which is
different on armhf and arm64
On armhf opengles2 is enabled whereas on arm64 it is disabled.
Since python3-pyside2.qtgui Build-Depends on qtbase5-dev the patch
doesn't really
work in the Debian context on arm64 - the package will build but the
dependencies
calculated by shlibdeps will be wrong for gles.
I tried to fix the problem by rebuilding changing the Build-Depends on
qtbase5-dev
and qtbase5-private-dev to qtbase5-gles-dev and qtbase5-private-gles-dev.
But that results in a build dep conflict because some of the other dependencies
(like libqt5charts5-dev) depend on qtbase5-dev (which conflicts with
qtbase5-gles-dev)
