SimulIDE / Discussion / Bugs, Errors and Other Problems: Segmentation fault on Arch Linux 64bits

max1858 - 2019-07-09

I'm on Arch Linux 64 Bits.
Frequently I experience shutting down of the program.
I've tried to run it from terminal and the only message is "segmentation fault".

Yes there are still some nasty bugs.

I guess you are using 0.3.10-SR2

Some bugs might be already solved.
But it would be very useful to know what was the program doing when it crashed.
if you get a case you can reproduce it would be ideal.

Looks like you are using 0.2.9-SR1 branch, better use trunk.

This bug might be solved.

Thanks for reporting.

I forget why I stopped using trunk, I bet it was because it dosn't build. I setup CI for my gitlab repo. This does two things, it let's ppl download the last version that builds and it provides *working build instructions.

It specifyed what docker container to use and wjhat commands are nessisary to setup that docker.
