I think I have figured out the problem. I had a locally built and cached wheel of PyQt5-sip from before PEP573 went in. If that wheel is used for later commits I get the segfault, if I rebuilt the wheel from source it works. I am not sure if this is an expected sharp edge (wheels are be expected to be good between commits prior to a release) or not. ----- Below is a script that will build everything (sip, pyqt5, pyqt5-sip) from source and install them into a virtual env. ---- #! /usr/bin/bash set -e set -o xtrace rm -r ~/.pybuild/py39 || true pushd cpython git clean -xfd ./configure --prefix=/home/tcaswell/.pybuild/py39 make -j 9 make install popd ~/.pybuild/py39/bin/python3 -m venv --copies --clear ~/.virtualenvs/py39 source ~/.virtualenvs/py39/bin/activate pip install --upgrade pip echo $PATH pushd PyQt5 pip install sip --no-binary sip rm -rf PyQt5-5.14.2 tar -xzf PyQt5-5.14.2.tar.gz pushd PyQt5-5.14.2 python configure.py --confirm-license # patch the one palce that does not respect the venv settings sed -i 's|$(INSTALL_ROOT)/usr|$(INSTALL_ROOT)/$(HOME)/.virtualenvs/py39/usr|g' Makefile make -j 9 make install popd popd pip install PyQt5-sip --no-binary PyQt5-sip python -c "import PyQt5.QtCore; PyQt5.QtCore.Qt.Key_Control" ---- ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40574> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
