9:31 a.m.
I'm working on building PySide2 for Fedora and have a problem with clang
segfaulting only on armv7hf[1]...
The source package has shiboken2, pyside2, and pyside2-tools in one big
archive but I am building shiboken2 and pyside2-tools with GCC and only
pyside2 with clang because if makes use of something clang specific.
