[Qt-interest] startDetached not working for standalone prog

[Jason H]

I poked around, and nothing was immediately obvious.
I will suggest though on a completely unrelated point that you don't check in Makefile and moc_* files. These are directly derived from .pro and your .h files respectively, much like an binary or library. So don't check those in.

Also, I'd suggest reading about QSettings if your settings get any more complicated.

Back to your issue, I've not experienced the behavior you are with QProcess in my own use. 

Try starting BASH (or whatever) and have it print the environment variables and see if there are any differences.

My knee-jerk reaction is to say getOctavePath() is not working the same. Are your relying on an environment variable and not set it?

getOctavePath()  is always working  It starts octave from all 4 of your scenarios.

The last 2 options Octave starts up and shows the correct graph and then closes.

The commands to octave are Identical.

The code is at:

I am running in  Ubuntu
