virtualbox render system exception

[ejtttje]

I'm trying to run Ogre 1.6.2 in VirtualBox 2.2.0, with Linux (Ubuntu 8.04 64bit) as the guest (i.e. where I am running Ogre), and OS X 10.5 as the host.

I think I have everything installed and built, but when I try to run any of the sample programs I get:

Loading library /usr/local/lib/OGRE/RenderSystem_GL.so
Installing plugin: GL RenderSystem
OpenGL Rendering Subsystem created.
terminate called after throwing an instance of 'Ogre::RenderingAPIException'
what(): OGRE EXCEPTION(3:RenderingAPIException): No GLX FBConfig support on your display in GLXGLSupport::GLXGLSupport at OgreGLXGLSupport.cpp (line 788)

Here's info from glxgears -info:

$ glxgears -info

Is there a way to get this working? I do most of my dev on the OS X side, but it would be nice to do some quick sanity checks on the linux side too via the VM.

Thanks!

Virtual Box doesn't support 3d acceleration as of yet.

Virtual Box doesn't support 3d acceleration as of yet.

Except, as of 2.2.0, it does.

OpenGL 3D acceleration for Linux and Solaris guests (see chapter 4.8, Hardware 3D acceleration (OpenGL), User Manual page 70)

(Actually 2.1.0 already had acceleration, but only for 32-bit Windows guests... 2.2.0 adds linux and solaris support.)

I've learned on another forum that the "GL_VERSION = 1.5 Chromium 1.9" refers to GL 1.5 support. According to the wiki, Ogre requires 1.2.1, so this should be able to work? Is there an ogre.cfg string I need to add or something to get around the FBConfig usage?

Alternatively, I'm not really concerned with performance anyway, I just want to launch my app and look around. Even if it were software emulated GL, that's not the end of the world — any suggestions how to switch to software rendering on Ubuntu 8.10 until they improve the driver?

You can select something other than FBO support (assuming alternate options are available in non-Windows builds) in the Ogre config dialog, and see if that works.

[ejtttje]

The exception is thrown before it gets a chance to put up the config dialog.

If I comment out Plugin=RenderSystem_GL in plugins.cfg, then it does put up a config dialog asking me to choose a render system, but the drop down box is empty and it throws a different exception regarding an empty menu if I try to click it.

Hello everyone, I am also trying to run any of the samples applications (Ogre 1.7) under a Ubuntu 9.04 guest using a Windows XP Host. Everything compiles. When I run any sample application I get the same error that ejtttje got (in the ogre log) back then.

Loading library /usr/local/lib/OGRE/RenderSystem_GL.so

But NOTE I am using Virtual Box 3.02 which officially supports Opengl 2.0.

VirtualBox 3.0.0 (released 2009-06-30)
This version is a major update. The following major new features were added:
* Guest SMP with up to 32 virtual CPUs (VT-x and AMD-V only; see chapter 3.7.2.2 of the user manual)
* Windows guests: ability to use Direct3D 8/9 applications / games (experimental; see chapter 4.8 of the user manual)
* Support for OpenGL 2.0 for Windows, Linux and Solaris guests http://www.virtualbox.org/wiki/Changelog

Also about this..,

You can select something other than FBO support (assuming alternate options are available in non-Windows builds) in the Ogre config dialog, and see if that works.

When I run the application, it does not even get to the config window.

Does anybody have any idea how to fix this?

I know it might not seem important but I think it is cool to be able to develop ogre under virtual machine.

Also another question, Does Ogre work with Mesa3d drivers or any other Software renderer?

[jacmoe]

Nope.
Ogre doesn't work with software renderers.
And I can't get it to work with VirtualBox either.
Doesn't matter if it's OpenGL or D3D. No dice.

[ejtttje]

Can you expand a bit on the technical reasons why software renderers won't work? Maybe somebody could actually fix this if it was advertised what was wrong. Intuitively, I don't expect the OpenGL driver should matter so much. If it claims to support some minimal OpenGL version X (2.0?), then why does Ogre care what's running under the OpenGL API abstraction?

I'm also guessing if it doesn't work with software rendering, it probably won't work on older graphics cards either. It would be nice not to require a high-end system for relatively simple apps like mine.

In any case, I seem to have gotten Ogre running under Mesa on Fedora, with the caveat of the lighting/shading being wrong (and perhaps that could be fixed with a bit of light/material configuration?) My thread on this (with screenshots) over here:

Good luck finding a 3D rendering engine which uses a software renderer.
Crystal Space abandoned their software renderer last autumn. (Pretty historic moment, IMO).
For good reason.
Even the most crappy graphics card these days are hardware accelerated.

Irrlicht has two!

[Kencho]

The point is that Ogre is a realtime rendering engine. Nice-looking graphics at decent speeds can't be done (well, it's possible but not acceptable nowadays). You would have to choose between 320x240 or <1 FPS.

I think you're misunderstanding the situation. As far as I can tell, Crystal Space had a custom, dedicated software renderer which replaces OpenGL.

I'm not suggesting Ogre should provide such a thing. I'm saying that if Ogre has a minimum of say, OpenGL 2.0, then if Mesa (an OpenGL implementation on Linux) provides OpenGL 2.0 support, what is the problem? If I run glxgears, it runs regardless of which OpenGL driver is being used. So what, specifically, is missing from a "software" implementation of OpenGL that makes Ogre unhappy?

As a further mental exercise, Intel is working on their crazy massively multicore CPU rendering stuff. If they provide a OpenGL interface, are you going to call that a "software renderer" and ignore it because it's running on CPUs instead of GPUs? Or is that going to be hardware accelerated "enough"?

Secondly, I've already demonstrated Ogre running on Mesa, so it obviously "works". With some minor attention to shading tweaks, it could be usable for testing or small applications.

Even the most crappy graphics card these days are hardware accelerated.

Well, that's assuming drivers are available (e.g. ATI dropping support for their x1600's among others which are only a couple years old, screwing laptops with those graphics chips), and also that you're running natively (e.g. VM 3D acceleration is spotty). And also you still haven't explained what a "crappy" graphics card can provide that the software driver can't, other than more FPS. I think there's a section of users more concerned with basic functionality than FPS count.

The point is that Ogre is a realtime rendering engine. Nice-looking graphics at decent speeds can't be done (well, it's possible but not acceptable nowadays). You would have to choose between 320x240 or <1 FPS.

Fair enough, but I can deal with low res/framerate for quick testing on low-end systems just to make sure it's working. It also helps to show my software is actually working and it's the local user's problem for not getting their driver installed correctly. And for simple scenes like I posted in the other thread, I was still getting ~10fps at 800x600, so that's almost usable.

[ejtttje]

Is there any progress on this? I'm still seeing the error, and I still don't understand the basis of the GLX FBConfig error. I have hardware acceleration. I have OpenGL 2.0. The only difference is it's running through a VM, but other 3D apps are launching fine, just not Ogre. Can we at least determine if this is something that Ogre is mis-detecting, or some edge case that Virtualbox needs to fix?

Currently testing with Ogre 1.6.4, Virtualbox 3.0.10, Ubuntu 9.10 guest, Mac OS X 10.6 host.

Think there's no relation to VirtualBox, because i've got no troubles using latest checkout of python-ogre. This issue is smth about incorrect checking of GL extensions. MB python-ogre works fine because of some exception been catched.

[tuan kuranes]

@ejtttje :
Ogre uses its own GLEW version (glew.cpp is on the ogre tree, ogre doesn't link to glew either statically or dynamically.), so testing glewinfo doesn't really help testing Ogre use of glew

You have to try compiling Ogre with the system provided glew. (the one that cames with your linux distribution)

Related post :
http://www.ogre3d.org/forums/viewtopic. ... 3&start=50

System glew use patch:
http://cvs.fedoraproject.org/viewvc/dev ... iew=markup

(check http://cvs.fedoraproject.org/viewvc/devel/ogre/ for all patches.)

if that works for you, you can provide a patch on ogre sourceforge tracker or/and post to ogre "feature request" forum.
Ogre might have to update "its" glew anyway in order to get opengl 3.X updates.

Are there any news on this? Has anyone been able to run Ogre under VB?

If this worked, it would be a life saver for me!

Thanks,
Mike

As much as I hate to practive thread necromancy with my first post here:

Is there any progress being made into the cause of this issue? I'm quite happy to test to help solve it as it would be incredible useful for testing our application on multiple systems.

[jacmoe]

I haven't been able to make that crap work.
The problem is that we need real access to the hardware.
But, of course, it would be nice if it did work..

[ejtttje]

It would help to explicitly mention what isn't working, i.e. what "real hardware access" you have via an ATI or nVidia driver that you don't have via the Chromium driver exposed by VirtualBox. Is it something to do with FBconfig? I started a thread about that over here, although I've been meaning to follow up on tuan kuranes's post in this thread which seems related. (edit fixed URL)

[jacmoe]

You are linking back to this topic!

I don't care about fbconfig - tried it on Vista, and it didn't work.
I'll give it a go with the newest VirtualBox, though.
My card is a [s]crappy[/s] regular nVidia 8500 GT.

I am also interested in making it work, because it would make it so much easier to test if our Ogitor installers works on clean systems.

[ejtttje]

*facepalm* sorry, I meant this one: http://www.ogre3d.org/forums/viewtopic.php?f=2&t=54081

[XenoPhoenix]

Yes ejtttje, I experiance the problem In exactly the same way as you do,

jacmoe yeah same reason here, we are making our application multiplatform and I simply don't have the number of machines I require to test each build and dual booting everytime is a real pain. Also using Ogitor, very nice and very useful that it does work on linux too

EDIT: I'm testing with a 8800GTX on Win7 x64 (with ubuntu x64 9.10 guest)
