How to repro
fn main() {
// Create the window and the event loop
let event_loop = EventLoop::new();
let window_builder = WindowBuilder::new();
// Create the opengl context, make it the current one (selected) and
// load its functions from the graphics device into the current process
let context = glutin::ContextBuilder::new()
.with_gl(GlRequest::Specific(Api::OpenGl, (2, 1))) // <- the version
.build_windowed(window_builder, &event_loop)
.unwrap();
let context = unsafe { context.make_current().unwrap() };
if !context.is_current() {
panic!("Couldn't make the context the currnt");
}
gl::load_with(|s| context.get_proc_address(s).cast());
let version = unsafe {
std::ffi::CStr::from_ptr(gl::GetString(gl::VERSION) as *const _)
.to_str().unwrap_or("NOT LOADED")
};
println!("OpenGL version: {}", version);
}
Goes back to the latest version (4.6.0 in my case), it lets me use the 3.x versions without issue, 1.x, 2.x impossible
