as a 1st test of this pyside build, a downstream build of Pyside&Shiboken-dependent FreeCAD, using the install described in this^ thread,
with config including ... -DPySide2_DIR=/usr/local/lib/cmake/PySide2-5.14.1 \ -DShiboken2_DIR=/usr/local/lib/cmake/Shiboken2-5.14.1 \ -DPYSIDE2RCCBINARY=/usr/local/bin/rcc \ -DPYSIDE2UICBINARY=/usr/local/bin/uic \ ... _does_ complete without apparent error FreeCAD --version FreeCAD 0.19 Revision: 19717 (Git) ldd `which FreeCAD` | egrep -i "pyside|shiboken|pivy" libpyside2.cpython-38-x86_64-linux-gnu.so.5.14 => /usr/local/lib/libpyside2.cpython-38-x86_64-linux-gnu.so.5.14 (0x00007f7f2ca10000) libshiboken2.cpython-38-x86_64-linux-gnu.so.5.14 => /usr/local/lib/libshiboken2.cpython-38-x86_64-linux-gnu.so.5.14 (0x00007f7f2c7c5000) (again, note libs are in wrong-arch libdirs, /lib not /lib64 ...) on launch, the app _does_ start, and seems nominally functional. non-fatal launch errors include, During initialization the error "No module named 'PySide2'" occurred in /usr/local/FreeCAD/Mod/Tux/InitGui.py Please look into the log file for further information During initialization the error "No module named 'PySide2'" occurred in /usr/local/FreeCAD/Mod/AddonManager/InitGui.py Please look into the log file for further information During initialization the error "No module named 'PySide2'" occurred in /usr/local/FreeCAD/Mod/Draft/InitGui.py Please look into the log file for further information Error: Pivy not found, Draft Workbench will be disabled. Unknown command 'Std_AddonMgr' I _suspect_ those are FreeCAD-config related; for later _______________________________________________ PySide mailing list PySide@qt-project.org https://lists.qt-project.org/listinfo/pyside
