Print Page - IllegalStateException: No context is current

Title: IllegalStateException: No context is current
Post by: fred_em on November 10, 2011, 16:05:37

Hi,

The following sample code works:


Display.create(); // create context with LWJGL

if (GLContext.getCapabilities().GL_AMD_debug_output)
{
    AMDDebugOutput.glDebugMessageCallbackAMD(new AMDDebugOutputCallback(
       new AMDDebugOutputCallback.Handler()
       {
           public void handleMessage(final int id, final int category, final int severity, final String message)
	   {
              [...]
           }
       }));
}

In my situation, I am not getting the GL context from Display.create().
The context is created and made active by another native library:

Code Select



// The following call calls wglMakeCurrent().
SomeObject.someNativeMethodThatCallsWglMakeCurrent();

GLContext.useContext(someGlobalObject);

/*
At this point I *can* use LWJGL functions like glBindBuffer and so on.
However, AMDDebugOutput.glDebugMessageCallbackAMD() raises the following exception:

java.lang.IllegalStateException: No context is current.
	at org.lwjgl.opengl.CallbackUtil.registerContextCallback(CallbackUtil.java:91)
	at org.lwjgl.opengl.CallbackUtil.registerContextCallbackAMD(CallbackUtil.java:154)
	at org.lwjgl.opengl.AMDDebugOutput.glDebugMessageCallbackAMD(AMDDebugOutput.java:80)

Why ?
*/

Any idea? I'm stuck.

Thanks,
Fred

Try the next nightly build, it should be fixed now.

It works fine with LWJGL 2.8.2.
Thanks.
