we are trying to draw simple square using LWJGL 3. On one computer it works fine but on my PC it throws an error.
My draw looks like this.
glBegin(GL_QUADS);
{
glVertex2f(0.02f, 0.02f);
glVertex2f(0.1f, 0.1f);
glVertex2f(0.02f, 0.1f);
glVertex2f(0.1f, 0.02f);
}
glEnd();
It doesn't work also when I, for example, want to draw a simple line.
glBegin(GL_LINES);
{
glVertex2f(10, 10);
glVertex2f(20, 20);
}
glEnd();
Every time it throws an exception from this function.
public static long checkFunctionAddress(long pointer) {
if(pointer == 0L) {
throw new IllegalStateException("Function is not supported");
} else {
return pointer;
}
}
Error looks like this.
Exception in thread "main" java.lang.IllegalStateException: Function is not supported

Does anybody know how to fix this issue?
Ok, so we have been looking for a answer for few hours and we figured out, that it was the driver problem.
I have installed a proper driver on my pc and it works fine now. You can find a link to install the driver on this page https://www.opengl.org/wiki/Getting_Started#Downloading_OpenGL.
