Demo: main panicked - Result::unwrap() - Err value: "GL context creation failed"

[Webtest7]

NEWBIE ALERT! I am very new to 'rust'. I got a few primitive things running and found this demo of a graphics app which I want to try to see if I want to continue with 'rust'.
It builds normally, but when it runs, it aborts with an error message:

• thread 'main' panicked at 'called Result::unwrap() on an Err value: "GL context creation failed"', libcore/result.rs:945:5
  note: Run with RUST_BACKTRACE=1 for a backtrace.

I tried to figure out the BACKTRACE stuff, but wasn't able to ... It disappears from the environment as soon as it is put in ??? I don't know what I am doing yet.

Here is my system info - I hope it is enough:

I spent several hours googling for a resolution to this problem with NO success.
Thank you for any and all comments, suggestions, and assistance.

The backtrace issue works as follows:
Instead of cargo run
you should use RUST_BACKTRACE=1 cargo run

Of course, replace it command with whatever command you are actually using to run the pogram.

Some additional context is necessary here. What part of the tutorial are you currently try out? Which program are you trying to run?

[HeroicKatora]

Your issue might be the one mentioned in the top-level Readme as well:
"I get "GL context creation failed" when running an example.

[Webtest7]

I thought I was in the "spinning-square" section - that's what I'm trying to run. Thanks for the backtrace hint - I'll try it. I saw the comment about the Readme, but I couldn't figure out where is the helloworld.rs. Why not just make it a link for us newbies? I tried a site search but it didn't find anything. Thanks & Blessings - Art

[Webtest7]

Ahh ... "top-level" HelloWorld ... I found it but it was of ZERO help. The similar note in the spinning-box demo is 'almost' clear, but making the change did NOT work at all:

// Change this to OpenGL::V2_1 if not working.
let opengl = OpenGL::V3_2;

I came across the "piston-window" app in Start new project with Piston and tried it ... it failed with exactly the same error. There is a blink of a window that is created, but it immediately crashes. Thanks to the hint re: backtrace, I was able to use it ... "vidtest" is the project name I gave to "piston-window" ...

We are having an awful lot of trouble with such an elementary "Getting Started" program!

Wrap the backtrace in a code block, that probably works best

I've read more about Mesa and OpenGL ... here is more information about my system:

glxinfo
name of display: :0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.4

    Vendor: Intel Open Source Technology Center (0x8086)
    Device: Mesa DRI Intel(R) G33  (0x29c2)
    Version: 17.0.7

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) G33 
OpenGL version string: 1.4 Mesa 17.0.7

OpenGL ES profile version string: OpenGL ES 2.0 Mesa 17.0.7
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16

I've read that Mesa 17.4 might have resolved some problems, and that Mesa 18.0 is supposed to be out already ... is there any hope?
Thanks & Blessings ... Art

I've run this previously both on this laptop (linux) and cross compiled for raspberry pi. It's was a bit clunky (i.e. v.e.r.y. s.l.o.w...) but ran. Now when I try to compile it I get the same error and backtrace as @Webtest7 above. When I change the Cargo.toml from

[dependencies]
piston = "0.35.0"
piston2d-graphics = "0.23.0"
pistoncore-glutin_window = "0.42.0"
piston2d-opengl_graphics = "0.49.0"

to

piston = "0.36.0"
piston2d-graphics = "0.263.0"
pistoncore-glutin_window = "0.45.0"
piston2d-opengl_graphics = "0.52.0"

I get the following error due to winit being 'yanked' and 0.10.1 no longer existing.

    Updating registry `https://github.com/rust-lang/crates.io-index`
error: no matching version `^0.10.1` found for package `winit`
location searched: registry `https://github.com/rust-lang/crates.io-index`
versions found: 0.12.0, 0.11.3, 0.11.2, ...

    ... which is depended on by `pistoncore-glutin_window v0.45.0`
    ... which is depended on by `spinning-square v0.1.1 (file:///home/patrick/rust/getting-started)`

For me, changing to OpenGL::V2_1 worked.
I'm on HP Probook 6450b
