std::rt::start_on_main_thread no longer exists?

[bonsairobo]

I get the compile error
unresolved name std::rt::start_on_main_thread
when trying to build any of the examples. I also looked in rust's repo under libstd/rt and couldn't find any instances of the function "start_on_main_thread".

It's a side effect of this change. rust-lang/rust#10965. Alex posted a potential work around.

extern mod native;
extern mod green;

use std::task::TaskOpts;

#[start]
fn start(argc: int, argv: **u8) -> int {
    do native::start(argc, argv) {
        let mut pool = green::SchedPool::new(green::PoolConfig::new());
        let (p, c) = Chan::new();
        do pool.spawn(TaskOpts::new()) {
            println!("green pool");
            c.send(());
        }
        p.recv();
        pool.shutdown();
    }
}

Is native ready to be used?

error: Package examples/window depends on native, but I don't know how to find it

Compiling with rustc instead of rustpkg seems to work as a temporary work around. It looks like there is a bug in rustpkg.

extern mod glfw;
extern mod native;

use std::libc;

#[link(name="glfw")]
extern {}

#[start]
fn start(argc: int, argv: **u8) -> int {
    do native::start(argc, argv) {
        main();
    }
}

This seems to give me a working window.

I get a segfault. I've built glfw3 from master, glfw-rs from master (had to rename libglfw3.so to libglfw.so for linking to work), then compiled this:

// build command: rustc main.rs -o window -L../../../lib/i686-unknown-linux-gnu

extern mod glfw;
extern mod native;

use std::libc;

#[link(name="glfw")]
extern {}

#[start]
fn start(argc: int, argv: **u8) -> int {
    do native::start(argc, argv) {
        main();
    }
}

fn main() {
    glfw::set_error_callback(~ErrorContext);

    do glfw::start {
        let window = glfw::Window::create(300, 300, "Hello this is window", glfw::Windowed)
            .expect("Failed to create GLFW window.");

        window.set_key_callback(~KeyContext);
        window.make_context_current();

        while !window.should_close() {
            glfw::poll_events();
        }
    }
}

struct ErrorContext;
impl glfw::ErrorCallback for ErrorContext {
    fn call(&self, _: glfw::Error, description: ~str) {
        println!("GLFW Error: {:s}", description);
    }
}

struct KeyContext;
impl glfw::KeyCallback for KeyContext {
    fn call(&self, window: &glfw::Window, key: glfw::Key, _: libc::c_int, action: glfw::Action, _: glfw::Modifiers) {
        if action == glfw::Press && key == glfw::KeyEscape {
            window.set_should_close(true);
        }
    }
}
