LCNC 2.9.3 and Debian Bookworm Error : No module named 'OpenGL was created by dashy81
I am trying to build LCNC version 2.9.3 from source on Debian Bookworm.
Facing below issue seems related to OPENGL. Checked a few threads but the issue as per them shall have been fixed by now.
Just wondering if I am missing something obvious.
- Configured for ./configure --with-realtime=uspace
- All build deps are satisfied.
- No issues during build .
Here's the logs on running LCNC from cmdline.

Did you try the official ISO from here:
www.linuxcnc.org/iso/linuxcnc_2.9.3-amd64.hybrid.iso
-
You also do not have the real time kernel installed, so even if you get OpenGL to work, you can not use it to run a machine.
Usually OpenGL issues are related to graphic cards, so if you have one as an add on, remove it and try again.

try:
you may also need:
$ sudo apt install python3-openglyou may also need:
$ sudo apt install python3-gi-cairo

Awesome !!!!python3-opengl install made it to work !!
Thanks... Do I need python3-gi-cairo as well ?

No, if everything works now then you do not need it.

Thanks Tommy, I have one working m/c did some 2 yrs back similia PC with mesa 7i96S. That was done via the direct installation of 2.8.x version. But somehow later to get it working with do'nt remember which gui, I had to do lot of stuff which I do not even remember now 
But basically had to switch to classic ladder from some other hal and build linuxcnc 2.9 on debian 10 as the said gui worked better in 2.9.
So this time I really want to spend more time on building and customizing lcnc and create a distribution with only the needed components.
Do'nt want the machine to look like a linux desktop but a custom professional look. Only gui starts on powerup like professional machine. No additional menu, cmd prompt or any other applications.
Yes you are right, But I am doing a Building for Run In Place build.
I still am unclear how can I generate a prempt rt image like the one you pointed and put it as a standalone install so that I can take that create a bootable usb and install it on any new computer.

Ok, still, if you want to run machines with the image you created, you will need the RT-Preempt kernel.
Or if you want to run machines from parallel port use the RTAI kernel.
In any case, after installing said kernel, do boot into it and remove the generic kernel.

I guess somewhere I read about installing the RT kernel first to be installed and then switching to that kernel. Thats here I think:7.1. Installing on Debian Bookworm (with Preempt-RT kernel)I think To create a image similiar to the one you pointed This process shall be followed. That shall ensure that I can have an iso image which I can take to another PC and install directly on my actual machine running LCNC.
But at the moment I am following 2nd build type to create a debian package for me to install on the system I am running:
6.4.2 Building Debian Packages
After configuring and starting build, I get below error.
Build cmd: dpkg-buildpackage --pre-clean -j4 -b -uc

Be sure to test with dpkg-buildpackage -A/-B as the results may vary when only a subset is built
If the omission is intentional or no other helper can take care of this consider adding the
paths to debian/not-installed.
