#189052 — need a video function in wheezy

Greetings all;

I have a machine vision utility for use on a CNC machine, that uses 
gladevcp.

But the launching script, in xml, is looking for a specific lib:

 <requires lib="gtk+" version="2.24"/>

which if it ever did exist in wheezy, was since removed.

This script is of course editable, so are the functions that were in this 
lib, now available in a different package? If so, likely suspects 
please?

Thank you.

Cheers, Gene Heskett

What about libgtk-3-0?

https://packages.debian.org/stretch/libgtk-3-0

I have that, but this is wheezy, and the application has not yet been 
built on stretch. 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

/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. Perhaps one of them is the 
"magic twanger" needed?

Thanks David

Re: need a video function in wheezy

D'oh!  When replying to a post, I'm looking at the body of a message and 
tend to forget requirements stated solely in the subject line.


Have you searched through the releases of Wheezy to see if any have the 
specific version of the library you need?  If found, air-wall the 
machine, put in a new system drive, install that release, install the 
software, get it working, and never update.


Does anybody know if any hypervisors support real-time virtual machines?


Otherwise, it's a matter of finding the software maintainer and 
convincing them to bring the software up to date.

While I think the problem ought to be described in the subject of the

That is not how my network is configured.  The app is itself under 
continuous development, with an average of 2 updates a week.

That is beginning to sound like a worthwhile effort. But difficult when 
the names are all thats available in the README. Which I'll quote from 
here in case the publicity helps.

"Many Thanks from  Jacob Bogenschutz (bogie6040)  to the following:

Norbert Schechner (newbynobi)
Fernand Veilleux (FernV)
Slavko Kocjancic (eslavko)

They deserve all the credit, I just tweeked on they're stuff and put it 
together."

Just in case one of them is reading this list.. :)

I guess air-walling really isn't necessary -- the key idea was to get it 
working and then don't break it by updating anything.


But if you're updating with developer releases bi-weekly, then the 
fallback idea would be to use and track whatever distribution the 
developers are using.  STFW I found http://linuxcnc.org/ , dug around 
briefly, and saw mention of Ubuntu, but not the level of detail needed 
to carry through this idea.  I also saw the Debian-live based release, 
so I dunno...

I have 2 or 3 copies of that on dvd's, and that is the install that all 
my x86 stuff is running.

Have you tried googling for their usernames?

I just googled for newbynobi, got several hits, some of which are links to 
wikis or forums.  In particular, I found a post by him at a link to 
https://forum.linuxcnc.org/gmoccapy (sorry, that seems to be a generic link 
rather than to a specific page).

My guess is that if you join that forum you could access his "profile" or 
whatever they might call it), and, further, I suspect their would be some 
means to address a message to him of some sort (like a PM (private message).  

If it doesn't work on that forum, try some others, and try the other user 
names.

He's a moderator on that particular branch of the forum. gmoccapy is a 
competing with axis "gui" for linuxcnc.

Hi Gene,

I suspect that your tool was built with the naming conventions used by
Red Hat in mind.  You probably need to change lib="gtk+" to
lib="gtk+2.0".  Here is the link to the source package in wheezy:

https://packages.debian.org/source/wheezy/gtk+2.0

Another possible candidate would be lib="libgtk2.0-0" for the name of
the actual binary package.

Regards,

-Roberto

AFAIK, but I'll say I'm on the fringes of the developers world, 
RedHat/Fedora has never been a target to make linuxcnc run on. We've 
pretty consistently chosen a distro stable enough that it was usable for 
at least the duration of a LTS release, and that a decade ago was 
ubuntu, but its gotten so liquid that the switch was made to debian 32 
bit as a development system at about the 7.1 point of wheezy.  And it 
still favors the 32 bit versions because the 64 bit versions, with their 
much larger context switch stacks taking more time than is comfortable 
to tolerate in the everyday world of the shop floor. Even servo-based 
machinery, normally operated with an every 1 millisecond control loop, 
can get fussy when a context switch is 3 milliseconds. I have one 
machine, sort of an experiment, running Jessie on a raspi, that has 
quite a bit of its control structure running at a 100HZ rate for the 
manual input stuff, and that works great. But I may be the only one on 
this ball of rock and water doing it.

And that is not the machine I am trying to make this work on, this one is 
far more conventional, one of several older Dell's in my collection of 
machines.

4 people seem to be the heart of this particular machine vision accessory 
package for LinuxCNC, but I've no email addies for any of them. But I'll 
keep looking, maybe I can get lucky yet.

Thank you Roberto.

Cheers, Gene Heskett

That returns a more specific error:
