I'm trying to use EBOs but when using
glDrawElements()
its giving a
GL_INVALID_OPERATION
. Here's my code.

int vaoID = glGenVertexArrays();
glBindVertexArray(vaoID);

int vboVertID = glGenBuffers();
glBindBuffer(GL_ARRAY_BUFFER, vboVertID);
glBufferData(GL_ARRAY_BUFFER, vertices, GL_STATIC_DRAW);
glVertexAttribPointer(0, 2, GL_FLOAT, false, 0, 0);

int vboColID = glGenBuffers();
glBindBuffer(GL_ARRAY_BUFFER, vboColID);
glBufferData(GL_ARRAY_BUFFER, colors, GL_STATIC_DRAW);
glVertexAttribPointer(1, 4, GL_FLOAT, false, 0, 0);

int eboID = glGenBuffers();
glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, eboID);
glBufferData(GL_ELEMENT_ARRAY_BUFFER, elements, GL_STATIC_DRAW);

glEnableVertexAttribArray(0);
glEnableVertexAttribArray(1);

exitOnGLError("Before glDrawElements");
glDrawElements(GL_TRIANGLES, 6, GL_UNSIGNED_BYTE, 0);
exitOnGLError("After glDrawElements");

And my
exitOnGLError()
method is

private void exitOnGLError(String message)
{
    int error = glGetError();
    boolean hadError = false;

    while (error != GL_NO_ERROR)
    {
        System.err.println(message + " " + GLU.gluErrorString(error));
        hadError = true;
        error = glGetError();
    }

    dispose();
    System.exit(-1);
}

I'm confused, that it is unexpected that
glDrawElements()
throws
GL_INVALID_OPERATION
. From the docs, I've found that

Quote
GL_INVALID_OPERATION
is generated if a non-zero buffer object name is bound to an enabled array or the element array and the buffer object's data store is currently mapped.

Can anybody please say me where I'm doing wrong?

I got it fixed. This was a driver issue and updating the driver got it right.
