Error compiling 'Hello World' example: NoAvailablePixelFormat

[luisvgs]

Hello, I'm trying to run the code from the roguelike guide (http://bfnightly.bracketproductions.com/rustbook/chapter_1.html), but unfortunately I'm getting this error: thread 'main' panicked at 'called Result::unwrap() on an Err value: NoAvailablePixelFormat', src\libcore\result.rs:999:5

Here's the full backtrace:

What could be causing this error? I kindly ask for help. Thanks!

Recently checked that someone had the same issue in amethyst, the problem was solved by disabling multisampling. Is it possible to dissable it in rltk? Thank you.

I have two computers that I develop on. On one of these - the one without a discrete graphics card - rltk works fine. On the other, with a decent Radeon graphics card, I get the NoAvailablePixelFormat error. Both are Windows 10 machines, updated to the same level.

One of the most recent commits should fix this. I had another user report it and pushed a quick fix. For some reason, AMD graphics cards only work if you force Glutin to formally request sRGB format (it'll use it anyway!) on framebuffers, or a float rather than byte backing per color channel.

Yes, it works now! Thank you very much.

I am currently on rltk = "0.5.12" on Mac Os and I'm still experiencing this issue. Full stacktrace:
