Description

PyQt4 is no longer supported upstream: PyQt4 version 4.12.3 is the last version of PyQt4. "This is the last release of PyQt4. No more releases will be made." https://riverbankcomputing.com/software/pyqt/download --- It seems like the stable version is now PyQt5: "PyQt5 is a comprehensive set of Python bindings for Qt v5." PyQt5 is packaged in Fedora as: https://src.fedoraproject.org/rpms/python-qt5/blob/master/f/python-qt5.spec I don't know if Qt5 is backward compatible with Qt4. Is it possible to consider removing the PyQt4 package in Rawhide? The following packages require PyQt4: * PyMca * flatcam * ibus-bogo * pymol * python-pyqtgraph * python-qdarkstyle * python3-PyQt4-devel * python3-PyQt4-webkit * python3-cclib * python3-iep * python3-matplotlib-qt4 * python3-pyqtgraph * python3-pyudev-qt4 --- The issue comes from qpycore_encode() function of PyQt4. First of all, this function is deprecated: "#if QT_DEPRECATED_SINCE(5, 0)" Morever, qpycore_encode() has been removed from PyQt5. PyQt 5.15.1 doesn't use PyObject_AsBuffer() anymore (the discussed function removed in Python 3.10). --- The Fedora package uses PyQt4 version 4.12.3 since August 2018: * Fri Aug 31 2018 Rex Dieter <rdieter> - 4.12.3-1 - 4.12.3 I'm working on a fix: https://src.fedoraproject.org/rpms/PyQt4/pull-request/2 |
