Something about being incompatible with rtai kernels newer than:
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 machinery. 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 particular library. 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: gene@GO704:~/linuxcnc/configs$ ls -laR /usr/lib/i386-linux-gnu|grep libgtk drwxr-xr-x 2 root root 4096 Oct 5 2015 libgtk2.0-0 drwxr-xr-x 2 root root 4096 Jun 5 2016 libgtk-3-0 lrwxrwxrwx 1 root root 19 Oct 28 12:12 libgtk-3.so -> libgtk-3.so.0.400.2 lrwxrwxrwx 1 root root 19 Oct 28 12:12 libgtk-3.so.0 -> libgtk-3.so.0.400.2 -rw-r--r-- 1 root root 4990504 Apr 17 2016 libgtk-3.so.0.400.2 lrwxrwxrwx 1 root root 29 Oct 28 12:12 libgtksourceview-3.0.so.0 -> libgtksourceview-3.0.so.0.0.0 -rw-r--r-- 1 root root 492616 May 15 2012 libgtksourceview-3.0.so.0.0.0 -rw-r--r-- 1 root root 7216108 Aug 6 2012 libgtk-x11-2.0.a lrwxrwxrwx 1 root root 27 Oct 28 12:12 libgtk-x11-2.0.so -> libgtk-x11-2.0.so.0.2400.10 lrwxrwxrwx 1 root root 27 Oct 28 12:12 libgtk-x11-2.0.so.0 -> libgtk-x11-2.0.so.0.2400.10 -rw-r--r-- 1 root root 4656508 Aug 6 2012 libgtk-x11-2.0.so.0.2400.10 /usr/lib/i386-linux-gnu/libgtk2.0-0: /usr/lib/i386-linux-gnu/libgtk-3-0: Note that the first 2 subdirs are empty, however there are libgtk-this and that packages that are not installed.
