I have that, but this is wheezy, and the application has not yet been
built on stretch. Something about being incompatible with rtai kernels
gene@GO704:~/linuxcnc/configs/GO704fast$ uname -v
#1 SMP PREEMPT Debian 3.4.55-4linuxcnc
as the app needs decent realtime performance. It is running heavy
It also changes the error message by changing "gtk+" and "2.24" to
"gtk" and "3.0.0" which I have in /usr/lib/i386-linux-gnu. But the
video still doesn't work. It does work when using qv4l2 to view the
camera output. But an lsof while its running says it is not using that
This library overlays aiming target patterns like circles and crosshairs
on the video I believe.
And a couple months back, it worked most of the time. It would fail if
the parent apps window for its display was drag expanded to more than
480 pixels high.
So how do I change this line in the xml launcher, so it works with the
newer version that I do have.
<requires lib="gtk+" version="2.24"/>
This is what I have:

Note that the first 2 subdirs are empty, however there are libgtk-this
and that packages that are not installed. Perhaps one of them is the
"magic twanger" needed?
