[FIXED] OpenGL ES 2 missing nglGetVertexAttribPointerv

[xranby]

Hey frostybeard, any news?

Has anyone else tried building and testing the ES branch?

Hi I have today managed to build the lwjgl 2.8.0 release on a ARM TrimSlice Ubuntu 11.04 machine powered by a Nvidia Tegra 250.

I had to patch the project a little to get it building by first fix and apply the latest Debian lwjgl 2.7 patches and then add a opengl-es patch that enabled the opengl-es compilation.
I have uploaded my patched and compiled source tree to:
http://openjdk.gudinna.com/lwjgl-es/LWJGL-2.8.0-armel-ubuntu-es.tar.gz (42mb)
sha256sum 9e6558aa3017f288d9eb3fdb72e3197faec39ecac368adc2a79c60e3be3fcf7d
You can also check the
http://openjdk.gudinna.com/lwjgl-es/LWJGL-2.8.0-armel-ubuntu-es-patches/
folder for.. patches!

When I run it I then hit what looks like an unimplemented part of the
"Linux for Tegra release 12 Alpha 1" Nvidia Tegra 250 opengl-es 2.0 driver.

Try adding an @Optional annotation on templates/org/lwjgl/opengles/GLES20.glGetVertexAttribPointerv, do a generate-all, then build again.

Unfortunally adding the @Optional annotation did not work...
i kept hitting the same error while init GLES20

I ended up  testing:

While i did not want to dig down into annotations today i simply commented out the problematic blocks and by doing so the following niceness happened...

Nice!

Could you please do an svn update? I've fixed @Optional and it should work on GLES functions now. Looks like OES_mapbuffer needs an @Optional too, I'm guessing on glGetBufferPointervOES (run with org.lwjgl.util.Debug=true to verify).

I've also added support for NV_platform_binary.

Thank you, after the update the @Optional annotation *almost* work... the missing part are that the
if (ext_func_pointer == NULL)   in  src/native/common/common_tools.c never turns true since ext_func_pointer are not NULL when nglGetVertexAttribPointerv are missing . Observe in the first log that the throwException(env, "Missing driver symbols"); never gets executed...  ... i am still working on this bug.

Ouch...

Ignore what I said about @Optional, I've fixed the real problem. Update and build again please.

Work!
Thanks a lot!
I have tested it running the following three demos:

java -cp libs/lwjgles_test.jar:libs/lwjgles.jar:libs/lwjgl_util.jar -Djava.library.path=bin/lwjgles org.lwjgl.test.opengles.FullScreenWindowedTest

java -cp libs/lwjgles_test.jar:libs/lwjgles.jar:libs/lwjgl_util.jar -Djava.library.path=bin/lwjgles org.lwjgl.test.opengles.Gears


The attached patch are now all needed to make LWJGL work out of the box using the "Linux for Tegra release 12 Alpha 1" drivers!.

[spasi]

Are you sure that patch is needed? Have you tried removing @Optional from glGetVertexAttribPointerv and glShaderSource3?

I was not sure, I have now tested without the patch.. and it work as well!
This bug are fixed! cool!
