Re: [osg-users] How to properly compile osg with EGL support?

[Roy Lichtenheldt]

Hi,

@Chris: I fear I will only be able to try that after my vacation.

As for the GPU-affinity:
I didn't have the chance to test the GPU-affinity part though since the 
self-administrated machine only got one GPU.

I will definitely let you know once I tested it and share it then.

Cheers,
Roy

[Trajce Nikolov NICK]

we are very interested in hearing about the "GPU affinity" approach you are
mentioning as you know

Re: [osg-users] How to properly compile osg with EGL support?

[Chris Hanson]

Can you just side-load the binary built on the personal machine onto the
administered system and see what happens? The result, even if it's a
failure, might be insightful.

I'm glad the process works. We need to document this build recipe because
the utility of it is potentially very powerful for many users.

Now we just need to figure out binding to a particular GPU in multi-GPU
systems, and it will be a serious breakthrough to be able to access
multiple GPUs on Linux without the overhead of X!

Re: [osg-users] How to properly compile osg with EGL support?

[Roy Lichtenheldt]

Hi Nick,

Thanks for the hint. After being unsuccessful on our administrated systems, I 
ported a small example to a self-administrated ubuntu machine --> few adaptions 
to the cmakeLists and it runs. I guess everything is running fine, as the 
viewer loop keeps running without showing the viewer on the screen (I ran the 
main.cpp from the repository in this thread).

So my next task will be to figure out what is wrong in the administrated system 
and to try our simulation tool on the ubuntu one in order to see if it would 
also work.

Thanks Again!

Cheers,
Roy

Re: [osg-users] How to properly compile osg with EGL support?

[Trajce Nikolov NICK]

Hi Roy,

the CMakeLists.txt I posted are replacement of the osgviewer from the
repository. Just give it a try there in that scope and then we can
investigate further how to adopt it for the osgEGL project

[Roy Lichtenheldt]

Hi Nick,

Thank you very much! Unfortunately, I did not get it working yet: I got a 
similar solution as yours - I fear it is rather our institutional Linux might 
be the problem - I need to check if everthing is fine there in terms of 
libraries.

If I link only against the libraries your cmakeLists provides, I won't get my 
examples running with either EGL or OpenGL (I guess libGLX is missing then).

Could using OSG 3.4 be a problem? (currently porting to 3.6 is not a fast 
option as osg::program changed sufficiently)

Cheers,
Roy

 Hi,

 Sounds good. Tomorrow morning I will compile it. I will probably also
 make some changes in how GL is used in CMake since to make EGL work you
 need to link to GLVND GL. Thanks for the tips to get OSG to compile.

 If you have some code already I will gladly take a look and see if I

 Do you have a github repo?

[Omar Álvarez]

Could you open an issue so we don't pollute this discussion? We will find
out what is going on in Github.

[Roy Lichtenheldt]

Hi Omar,

I tried to run your example, but didn't succeed with compilation. I guess I am 
missing a step in compilation of OSG. Do you have any additional hints on that?

I also adapted our particle simulation (still based on OSG 3.4) to use an EGL 
context similiar to how you did it, everything compiles fine, but segFaults 
during the GL calls. (compiled OSG with added -lEGL, however it does not seem 
to make a difference)

Cheers,
Roy

Re: [osg-users] How to properly compile osg with EGL support?

[Omar Álvarez]

I have created a small repo with my changes based on your code. I will try
to update the readme today, but compiling it is pretty straightforward.

https://github.com/omaralvarez/osgEGL

I still need to clean up the code and see what is going on with the
warnings, but it looks like it is working properly with the OSG master
branch.

Re: [osg-users] How to properly compile osg with EGL support?

[Chris Hanson]

As far as integrating, I'd probably defer to Robert on his views of how it
ought to be tied in. Without X Server, a lot of the Windowing System code
kind of becomes moot.

Do you have any views on this Robert? I'd love to get this technique into
wider utilization.

Re: [osg-users] How to properly compile osg with EGL support?

[Omar Álvarez]

I have managed to compile and run a simple EGL example that Trajce Nikolov
kindly provided. I am preparing a github repo with the code, if he has no
issue with this. Here are the caveats that I have found:

- When installing driver we need to reboot in order for the EGL context to
be available. In Ubuntu 18.04 installing the latest drivers from NVIDIA PPA
worked out of the box.
- eglinfo is awesome. NVIDIA device EGL needs to be working to be able to
run EGL.
- When using the latest CMake (3.13.x), I think OSG does not properly
detect libOpenGL.so which is needed for EGL. I will test this further to be
sure that is the cause.
- One needs to stablish viewport resolution manually or the following error
pops up: "Error: cannot draw stage due to undefined viewport"
- Some warning pops up that I have not been able to fix: "void
StateSet::setGlobalDefaults() ShaderPipeline disabled."

Any idea why the warning message is popping up?

It would probably be interesting to integrate in OSG the graphics context
code, so that users don't need to write the custom class. If anyone has any
suggestions I would love to hear them.

I have managed to compile and run a simple EGL example that Trajce Nikolov
kindly provided. I am preparing a github repo with the code, if he has no
issue with this. Here are the caveats that I have found:

- When installing driver we need to reboot in order for the EGL context to
be available. In Ubuntu 18.04 installing the latest drivers from NVIDIA PPA
worked out of the box.
- eglinfo is awesome. NVIDIA device EGL needs to be working to be able to
run EGL.
- When using the latest CMake (3.13.x), I think OSG does not properly
detect libOpenGL.so which is needed for EGL. I will test this further to be
sure that is the cause.
- One needs to stablish viewport resolution manually or the following error
pops up: "Error: cannot draw stage due to undefined viewport"
- Some warning pops up that I have not been able to fix: "void
StateSet::setGlobalDefaults() ShaderPipeline disabled."

Any idea why the warning message is popping up?

It would probably be interesting to integrate in OSG the graphics context
code, so that users don't need to write the custom class. If anyone has any
suggestions I would love to hear them.

Re: [osg-users] How to properly compile osg with EGL support?

[Omar Álvarez]

Hi,

Sounds good. Tomorrow morning I will compile it. I will probably also make
some changes in how GL is used in CMake since to make EGL work you need to
link to GLVND GL. Thanks for the tips to get OSG to compile.

If you have some code already I will gladly take a look and see if I can
make it work. I’ll be happy to share my findings with everybody. If
everything goes ok we should have a working example and maybe a tutorial.
Do you have a github repo?

Regards,

Omar.

Re: [osg-users] How to properly compile osg with EGL support?

[Chris Hanson]

Based on what we've seen, the technique SHOULD work. I'm not in a position
to test and hack on it myself because I don't have an NVidia Linux box
handy.

It'd be good to have a standard example of osgViewerEGLnoX or something,
because there seems to be a growing number of folks who don't want an
XServer gumming up the works.

Re: [osg-users] How to properly compile osg with EGL support?

[Trajce Nikolov NICK]

Hi Omar,

we are trying to get this running as well. Julien's hints should be enough
to get it built. I also wrote some code to support EGL based on some
off-list disucussion we had with Chris. All was great but got some crashes
in osg and was not able to actually run it. I can share my work with you
(tomorrow) if you want to give it a try and maybe together we make it work
and share it with the community?

Cheers,
Nick

Re: [osg-users] How to properly compile osg with EGL support?

[Julien Valentin]

few advices:
check your driver support with eglinfo 
try adding -legl to the linker flags
try VERBOSE=1 make 
to check used linkerflags
Cheers

[osg-users] How to properly compile osg with EGL support?

[Omar Álvarez]

Hi.

I am trying to compile OSG with EGL support in order to be able to run OSG
server side without an X display server. I have installed EGL headers and
the latest and the NVIDIA driver. EGL is detected by OSG and I am
requesting GLVND GL:

cmake -DOpenGL_GL_PREFERENCE=GLVND .

I am getting linking errors:

[ 33%] Linking CXX executable ../../bin/osgversion
../../lib/libosg.so.3.6.3: undefined reference to
`glDrawArrays'../../lib/libosg.so.3.6.3: undefined reference to
`glCallList'../../lib/libosg.so.3.6.3: undefined reference to
`glPointSize'../../lib/libosg.so.3.6.3: undefined reference to
`glTexParameteriv'
../../lib/libosg.so.3.6.3: undefined reference to
`glFrontFace'../../lib/libosg.so.3.6.3: undefined reference to
`glLightModeli'../../lib/libosg.so.3.6.3: undefined reference to
`glGetBooleanv'.

Is this the proper way for compiling OSG with EGL support?

I am using CMake 3.13, Ubuntu 18.04 and gcc 7.3. I think the way in which
the OpenGL library is linked has to change (to support the new CMake flag
OpenGL_GL_PREFERENCE).
