I am using the glDebugMessageCallback() to get error messages but sometimes I don’t have a clue as to what they mean.
I am wondering if there is a wiki or pdf reference manual for error messages? Similar to what we can find on each OpenGL functions when they return an error.
Right now, I am getting this one that puzzles me:
gl error source API, type Error, id 1282, severity high, length 82 ‘GL_INVALID_OPERATION error generated. State(s) are invalid: program texture usage.’
I understand it is related to texture but that is about it. I don’t recall changing code around where it now fails. Perhaps I did but when checking the code and values passed, I do not understand what is wrong. The Texture_Array_ID and Texture_Array seem to have valid numbers. The texture array was properly created last time I checked and was displaying the various textures properly but not anymore.
Here is a bit of context. The error occurs at the glDrawElements():
... glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D_ARRAY_EXT, Texture_Array_ID); glUniform1i(Texture_Array, 0); glDrawElements(GL_PATCHES, ...);
