Non-Docker Installation #5

Closed yasirroni closed 3 years ago

yasirroni commented 3 years ago

Is it possible to use omnetpy without Docker?

In my case, the docker can't find OpenGL because I use NVidia (NVIDIA Corporation GK106 [GeForce GTX 660] (rev a1)) Driver in Ubuntu 20.04

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-userpp'
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
[osgEarth]* [Capabilities] Failed to create graphic window too.
Error: Unable to create OpenGL graphics context.
Loading OSG Viewer library...

So, is it possible to use it outside the Docker (because the driver exist outside the Docker)?

ps: Or you are interested to solve OpenGL Issue?

Everything that can be done in a container (docker or whatever containarization technology), can also be done in a non-containerized environment, provided that the correct configs, libs, runtimes, etc... are there.

I am sorry, but it is far outside my possibilities to provide non-docker instructions right now.

That said, maybe I can help you tuning the docker image build to meet your needs.

To better understand your situation, do you need to use OSG to run simulations? or is this preventing your from running anything? For instance, can you launch pytictoc, pyrouting, or any other pysample?

See this for instructions on how to run a pysample.

I'm following the pytictoc tutorial and it resulted in the same error:

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-userpp'
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

I'll keep try to find a proper NVidia Driver for the docker because I've not been able to install the driver inside docker.

Ps: how about make a Ubuntu 20.04 based image (because as far as I know, there is no problem with my graphic card with Ubuntu 20.04).

mmodenesi commented 3 years ago

I'll provide such an image in the next few days, I'll comment here.

yasirroni commented 3 years ago

Maybe, ubuntu 18 LTS would be easier as the base. It also supported by the original doc/InstallGuide.pdf installer tutorial.

mmodenesi commented 3 years ago

Take a look at https://hub.docker.com/repository/docker/mmodenesi/omnetpy

mmodenesi commented 3 years ago

If you use the image based on 20.04, take a look at this change https://github.com/mmodenesi/omnetpy/commit/326469a156eb5814bccc26d82e3933c7ecc32987

Let me know how this goes!

Edit: I can run pytictoc simulation using your default Ubuntu 19 image, but the error persist. I just don't know that I need to start the simulation (yes it's throw error, but the simulations seems working seamlessly) . My bad.

If you use the image based on 20.04, take a look at this change 326469a

Let me know how this goes!

I'll give an update next weekend if possible.

Take a look at https://hub.docker.com/repository/docker/mmodenesi/omnetpy

I'm trying ub20.04_opp5.6.2. Can you share with us the dockerfile so that I can help debug and modify if necessary? Maybe make separate branch to this repo?

yasirroni commented 3 years ago

Thank you, so far above problem is fixed, but the problem move to Omnet++. Moving to Omnet++ 6pre solve the issue on Ubuntu 20 (at least for my project that seems depend on Omnet++ 6pre.

mmodenesi commented 3 years ago

Great! I was trying to make ubuntu:20.04 and OMNeT++ 6pre{8,9,10} but I couldn't manage to compile correctly and the IDE was not available. Will take a closer look. Keep an eye on newer images on the dockerhub page.
