[OpenGL] VMware/VBox Support?

[QuarkRobot]

When running a programme on Ubuntu x64 (latest copy) with VirtualBox I get the following error when using Texture2D.FromStream AND New Texture overloads.

It appears similar to this issue: https://github.com/flibitijibibo/FNA/issues/296 but I can't fix it.

To be honest I'm a bit hesitant to try and debug a VBox instance because VBox totally blows to the point where even the kernel devs don't accept bugs for it anymore. Do you have a VMware Player setup to test with instead?

If I were to take this report at face value I would say that it doesn't like this call here...

https://github.com/flibitijibibo/FNA/blob/master/src/Graphics/OpenGLDevice.cs#L1392 https://github.com/flibitijibibo/FNA/blob/master/src/Graphics/OpenGLDevice.cs#L2069

... but again, it's VBox. This is probably one of many things it doesn't correctly support.

Yep, VirtualBox is nowhere near as good. The game launches now with VMware Player but crashes soon afterwards when loading a shader.

Here is the shader http://media.quarkrobot.com/downloads/shader.Fxc which was compiled and works on Mac and Windows as per https://github.com/flibitijibibo/FNA/issues/302 Here is the error details from the terminal:

Got a SIGABRT while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application.

Your FNA revision is out of date, update and that assert shouldn't be reached.

Though even then, the FBO incomplete message is probably going to hit you next. What's the host's GPU? Should this just be tested on a real box instead...?

[QuarkRobot]

I've added the mod from this issue: https://github.com/flibitijibibo/FNA/issues/310 Would you like me to update FNA? I've made quite a few mods to Song and MediaPlayer to add streaming from archive support and I'm not sure whether Git will keep them - sorry, total Git newbie here.

Host GPU is a Nvidia 770M MXM laptop card.

[flibitijibibo]

If the VertexAttribDivisor fix is there you should be left with whatever that FBO issue is... though why that's just in stderr/stdout and not an ARB_debug_output error I'm not sure.

In any case, try to keep up with FNA at all times. Falling behind is a really, REALLY bad idea. You can ask any FNA dev other than me about that!

[QuarkRobot]

Okay, FNA updated with a slightly different error location: /home/flibitijibibo/Programming/reProjects/MojoShader/mojoshader_opengl.c:2302: MOJOSHADER_glSetVertexAttribDivisor: Assertion `ctx->have_GL_ARB_instanced_arrays' failed.

I think I'll get someone to test on an actual machine and not a virtual one...

Update: it does sort of work on a proper Linux machine although not very well. Loading shaders appear to not work either. I'll close this because it is unrelated to a virtual copy of Linux.
