Panic XNotSupported running on Raspbian (Raspberry Pi)

[frederik-glasmachers]

I cross-compiled the application

#[macro_use]
extern crate glium;
fn main() {
    let display = glium::glutin::WindowBuilder::new().build_glium();
}

with the Cargo.toml

[dependencies]
glium = "*"

using a cross-compiler as explained at https://github.com/Ogeon/rust-on-raspberry-pi.
Notice that i do not call unwrap on the result, so the variable display is of type std::result::Result<_, _>.

On raspbian i started X, opened a terminal and started the application. The error

thread '<main>' panicked at 'callled `Result::unwrap()` on an `Err` value: XNotSupported', src/libcore/result.rs:731

was reported.

There is a function calling unwrap inside the glium::glutin lib thats causing the panic. I think this should be reported as an error-result instead.

But what can i do to make it run on the Raspberry Pi?

The changes in #602 will report an error instead of panicking and will indicate precisely what the problem is (instead of just XNotSupported).

The other part of the issue (the fact that it fails to load) is probably due to #554
