I'm uncertain whether this is an appropriate message for this list. If
not, say so and please accept my apologies.
I am testing a pyQt5 gui on a raspberry pi3. I get identical results
with both raspbian jessie and stretch.
I first got the error libEGL warning: DRI2: failed to authenticate. I
seem to have solved that by establishing symlinks to all libEGL and
libGLESv2 following this model
sudo ln -fs /opt/vc/lib/libEGL.so /usr/lib/arm-linux-gnueabihf/libEGL.so.
The next error was ** (python3:1422): WARNING **: Error retrieving
accessibility bus address: org.$.
This seems to be "solved" by export NO_AT_BRIDGE="1".
Now I am getting an intermittent Segmentation Fault. The script usually
seems to fail when the python routine implementing the .ui form is first
loaded. Occasionally, however, it works perfectly. The script always
works on my desktop LinuxMint18.
I am using QtCreator 5.7 on my desktop to create the .ui file. I
transfer it to the pi where I run pyuic5 (installed with 5.7) with
Any ideas what would cause the seg fault?
