Failed to compile some part of example from the website " rand::Rng().shuffle([1, 2, 3]) "

[cnd]

OS: Windows 7 32 bit, using MinGW version suggested by wiki (because last one just fails)

Trying to compile example from website.

description:

this code works:

use core::*;

fn main() {
    for ["Alice", "Bob", "Carol"].each |&name| {
        do task::spawn {
            io::println(name);
        }
    }
}

but when I add

let v = rand::Rng().shuffle([1, 2, 3]);

like

use core::*;

fn main() {
    for ["Alice", "Bob", "Carol"].each |&name| {
        do task::spawn {
            let v = rand::Rng().shuffle([1, 2, 3]);
            io::println(name);
        }
    }
}

it fails with error :

The procedure entry point ... rand... extension... not found in the .... dll

btw: why does rust code highlighting on github look like plain text?

This is likely a symptom of this terrible, terrible bug: #3660

The problem is that there are two sets of libraries installed, and we rely on the assumption that they are identical when configuring the $PATH environment variable, but that assumption has turned out not to be true for unknown reasons.

One possible terrible, terrible workaround is to add something like C:\Program Files (x86)\rust\bin\rustc\i686-pc-mingw\bin (verify that path on your own install) to the front of $PATH, but only when running the executable (not when running the compiler). That should dynamically load the library with the correct symbol. Alternately, you could just copy the files in that directory to C:\Program Files (x86)\rust\bin, which would make the two sets of libraries the same. It's a mess, sadly.

I'm not sure what the state of Rust syntax highlighting on GitHub is, but here is the issue: #4341.

@cynede - let me know if what @brson suggested works for you, and if it does, I'll close this as a duplicate of #3660. If it doesn't, we'll leave it open for now.

It works, thank you.
