[SOLVED] Export Graph Button causes runSofa to segfault (SIGSEGV) and crash

[Olumide]

Regardless of which scene I load whenever I press the “Export Graph …” button runSofa segfaults and crashes as shown below:

Furthermore, the “Edit >> Data Graph …” menu does nothing, even though I suspect its supposed to launch a dialog.

Dear @olumide

Thanks for highlighting this, this option is broken for some time. I think actually no one is really using it, I will discuss it on Wednesday dev meeting (every Wed on 10 am CET online, open to all). I created an issue here, feel free to watch this issue.

Best,

Hugo

[Olumide]

Hello Hugo,

Thanks for your reply. I too am not sure what the option does but I was hoping it would show how data flows within sofa and how the various visitors trigger each other, but maybe that’s too much to ask 😉

Regards,

A pull-request has been proposed to fix this.

I therefore close the topic.
Best wishes,

Unfortunately the export Graph feature still crashes when exporting the default scene. The dialog opens this time (yay, progress) but runSofa still crashes.

Dear @olumide

This is strange: I did not face this issue on Linux (Ubuntu).
You are using v20.12.01 (binary) apparently right?

Hugo

[Olumide]

Dear @Hugo,

Yes I am running the latest version 20.12.01, on Ununtu 18.04.5 LTS.

The problem appears to be with paths relative to home, specified with tilde e.g. ~/tmp/file.dot. The QlineEdit filename in /src/modules/SofaGuiQt/src/sofa/gui/qt/GenGraphForm.cpp appears to be empty which raises the unhandled SIGABRT signal.

No signal is raised for standard absolute or relative path such as /home/tmp/file.dot. and ../tmp/file.dot. However, in both cases the dot file created is an empty digraph as shown below:

digraph G {
}

Regards,

– Olumide

[Hugo]

Dear @olumide

Thanks for reporting this.
The issue was solved by Guillaume in PR #1948

I therefore close this topic.
Best wishes,

Hugo
