Hi!
My problem:
I'm using my Geforce Go 7400 under Windows Vista 32bit, installed the latest 101.41 drivers.
And I'm developing a software in java using jogl
Problem is: When calling the method glCreateShader oder glCreateShaderObjectARB I get an error message:
- [...] Method "glCreateShader" not available -

This sort of error message normally just occurs when using a method thats not supported by the hardware. But I have an idea that my card supports shaders...

It would be really cool, if some could help me finding a solution to my problem.

I didn't try too long, but it seems, that it's working with the old jogl, but not with the latest JSR231 1.1.0 RC3


Thanks!

Have you tried the latest nightly build?

What is the output of the jogl-demos demos.printext.PrintExt?

Are you using the GLCanvas or the GLJPanel?

Do the advanced demos like the HDR demo work on your machine? Have you tried using just the default GLCapabilities when creating your GLCanvas?

Thanks for assistance!

I'm using GLCanvas.
I just tried using the caps:
1  
2  
3  
4  
        GLCapabilities caps = new GLCapabilities();
        caps.setHardwareAccelerated(true);
        caps.setDoubleBuffered(true);
        GLCanvas canvas = new GLCanvas(caps);

But it|s not changing anything.

As well I tried the 1.1.0-pre-20070327-02:12:12 version.
All that didn't help.

Using the old jogl version (net.java.games.jogl) did work in terms that I didn't get any errors. Though I couldn't see the shader effect yet... I'm working on it.

demos.printext.PrintExt output:

So I can see at least GL_ARB_vertex_shader and GL_ARB_fragment_shader.

Oh yea the HDR demo works. But I looked at it and saw that the program is 'sumbmitted' not as shader in glsl.

Thanks for the help so far...

Please post a small and self-contained test case. The PrintExt example clearly indicates the appropriate extensions are available. Are you sure you're calling these methods while an OpenGL context is current? Have you tried installing the DebugGL pipeline in your init() method? See the source code for the Gears demo for an example. Does it report any errors?

Hi!

It works now! Thanks for the help. Smiley
I used the Debug pipeline before, but that didn't give me any errors.

But I than used the gears demo as you told me, and that worked.
So I added my shader class to that and at least I could create the shader. I found a few more little bugs that I than removed, so that it works now!  Grin

I just have to figure out what exactly the difference ist between the gear demo and my programming...

I'll let you know, in case someone has a similar problem.

Thanks!!

(btw. how do I activate this javadoc for intellisense in netbeans 5.5?)

Hi!
Alright, for the protocol:

Let me just show you what I changed in code:

BEFORE:
1  
2  
        this.context = .createContext(null);
        this.gl = this.context.getGL();


AFTER:
1  
2  
        this.context = gLAutoDrawable.getContext();
        this.gl = gLAutoDrawable.getGL();


That made the whole thing working.

Thanks, for the help!
