[qgroundcontrol] segfaults on start

[fcladera]

Hi,

I just compiled the latest version of QGC, and it is segfaulting as soon as I launch it. Here is the debug trace.

Program received signal SIGSEGV, Segmentation fault.

I did clean all the config files for QGC as well as the QGroundControl folder. Any hints are greatly appreciated!

hmm I'm not able to reproduce this. Can you ensure that you are building QGroundControl under a clean chroot? That might help sort out any potential build issues reflected during runtime.

[acxz]

In the meanwhile, take a look at installing qgroundcontrol from the arch4edu repository. https://github.com/arch4edu/arch4edu/wiki/Add-arch4edu-to-your-Archlinux

Building in a chroot env seems to do the trick. I apologize for this bad bug report.

Do you know why this issues happen with paru? I did not seem to have the same problem with yay.

[acxz]

I really couldn't tell you. yay and paru should have the same behavior, I'd say if you don't experience the error with makepkg and you do with paru, you should post an issue over at paru github.

Glad to hear you got it working tho!

👍🏼

Thank you so much for your hard work and effort with these packages!
