Linux SDK with mesa

and looking at it in a debugger and reading some code still doesn't make it obvious what the actual problem is.

X11 is asynchronous. You won't get a meaningful break point in the debugger unless you call XSynchronize(dpy, True); first. Some X apps have a special -sync commandline option for this.

The error however tells you exactly which GLX request failed (GetDrawableAttributes), which seems to be part of the GLX_SGIX_pbuffer extension (which as a quick grep shows is indeed used by the oculus SDK): https://www.opengl.org/registry/specs/SGIX/pbuffer.txt

However it doesn't look like a missing extension, but rather an invalid drawable being pased to the request.

Thanks for the explanation. I did try to call XSynchronize but maybe I did it in the worng place. Anyway, not so important.

Somehow I didn't manage to google without the GLX prefix...

So you think it's just a mesa bug?

Not necessarily, but it's possible. Can't really tell without deeper examination, and my main development box has an nvidia GPU.

If you manage to break at the point of failure and examine the drawable being passed by the SDK, you might be able to tell if a correct drawable is passed by libovr or not.

Sure, I can get this:

The drawable in question seems to be "31457282" and the failing call to be glXQueryDrawable() and from that GetDrawableAttribute().

If I break on XError the program gets paused while there is a window frame with transparent content visible. using xwininfo -int on it shows:

xwininfo -int

          would like information by clicking the

but before that:
GetDrawableAttribute does pdraw = GetGLXDRIDrawable(dpy, drawable);
GetGLXDRIDrawable does struct glx_display *priv = __glXInitialize(dpy); and then if (__glxHashLookup(priv->drawHash, drawable, (void *) &pdraw) == 0) is true (0 means found) and pdraw is returned, so this is still working so far.

I can read a bit more code but someone who knows mesa and Xlib and knows where to look and when something looks bad, would probably have success much quicker.

In case you didn't see this in the linux issues thread, this is your problem: viewtopic.php?f=20&t=16268#p213055

You should probably try the proposed fix and see if it works.

I have seen and tried it, but it didn't help against the X Error. But thanks for the suggestion.
Reading the several threads about linux there seem to be a lot of issues with the opengl implementation in the SDK that should probably first get fixed...

I think jherico has identified the problem: viewtopic.php?p=213090#p213388

The callback branch doesn't compile:

/home/chris/build/oculus-rift-sdk-jherico-git/src/OculusSDK/Samples/CommonSrc/Platform/Linux_Platform.cpp: In member function 'virtual ovrRenderAPIConfig OVR::Render::GL::Linux::RenderDevice::Get_ovrRenderAPIConfig() const':

Samples/CommonSrc/CMakeFiles/CommonSrc.dir/build.make:261: recipe for target 'Samples/CommonSrc/CMakeFiles/CommonSrc.dir/Platform/Linux_Platform.cpp.o' failed

But removing the two offending lines for now "fixes" that.

The BadDrawable XError is gone, now I'm getting the real errors:

failed: 0:4(12): warning: extension `GL_EXT_gpu_shader4' unsupported in fragment shader
0:26(14): error: `gl_FragCoord' redeclared
0:27(68): error: no function with name 'textureSize2D'

This is in the shader source code in LibOVR/Src/CAPI/GL/CAPI_GL_DistortionShaders.h.

I believe "_FS_IN vec4 gl_FragCoord;\n" can just be removed when it is "redeclared".

The textureSize2D function seems to be related to GL_EXT_gpu_shader4 so no surprise there.
It looks like mesa just doesn't have this... https://bugs.freedesktop.org/show_bug.cgi?id=70260#c2

The callback branch doesn't compile:

The callback branch SDK samples don't compile. I don't really spend much time working with the Oculus samples as they're very Direct3D focused, and they spend too much effort maintaining state. This in turn masks bugs in the SDK where it does stuff like change state and not restore it. Basically I don't consider the SDK examples a sufficient test for 'this SDK is working' so I simply don't use them.

If you want to try out my callback approach, you can use my corresponding examples callback branch here: https://github.com/jherico/OculusRiftInAction/tree/callback

Well, it would have been nice to have a default demo that at least does something in the upstream sdk. :)

Anyway, when I make a release build of OculusRiftInAction/build/output/Example_2_4_HelloRift it just fails with

Compiling shaders/Chapter5.vs
std::bad_alloc

When I make a debug build it doesn't (wtf?).
The good news is: It opens a window and renders something without crashing. YAY.

First there is still the problem with OpenGL core contexts in GLEW I think:
Mesa: User error: GL_INVALID_ENUM in glGetString(GL_EXTENSIONS)
It's been an open bug for 4 years or so: http://sourceforge.net/p/glew/bugs/120/

The following problems could of course have been caused by the glew extension string not working.

Then I get
Mesa: User error: GL_INVALID_VALUE in glPixelStore(param)
caused by:

Anyway, looks like progress is being made. Thanks for all that work you put into it.

Well, it would have been nice to have a default demo that at least does something in the upstream sdk. :)

Anyway, when I make a release build of OculusRiftInAction/build/output/Example_2_4_HelloRift it just fails with

Compiling shaders/Chapter5.vs
std::bad_alloc

When I make a debug build it doesn't (wtf?).

This is a known issue.

I'll take a look at the other stuff when I have a chance, but basically it looks mostly like it's issues with my use of OpenGL, not the SDK's use, so that shouldn't be a blocker.
