I keep getting weird errors (when trying to compile the Blending.java example)

Any1 know what stupid things this noob is doing? :oops:

What version are you using?

Seems you have a 0.6+ version (most likely 0.7-pre). and are trying to compile some 0.6 code.

The GL class has been made static in newer releases, and is thus accessed in a static context:
gl.clear(GL.COLOR_BUFFER_BIT | GL.DEPTH_BUFFER_BIT);
becomes
GL.glClear(GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT);

also,

Sys.getDirectBufferAddress(textureBuf) no longer exists, just supply the buffer as is (flipping if needed)

[Morgrog]

I'm currently using lwjgl-0.6-rh8.zip

and that was (Blending.java) from the lwjgl-source-.6.zip

I think I'm just gonna "reinstall" the whole package and then see if I still get the errors

[cfmdobbie]

Looks like you're trying to compile Blending.java without its dependencies - looks like it needs Texture.java and FiltersLightingAndControl.java at the very least.

Don't just pull one file out, pull them all out and try and compile them all at the same time.

[Morgrog]

yah, that's what I learned when searching a bit deeper.
Alas I can't test it now (since I'm at work), I'll check it out sometime later... Hopefully every thing will turn out ok (as I think it will)
