Thanks Mikhail,
I tried removing the "lang_items" entry in the feature list but I got the
same error.
So some hit and trial got me this and it seems to work
#![crate_name = "rustcode"]
#![crate_type = "staticlib"]
#![feature(lang_items)]
#![no_std]
#[lang="sized"]
#[no_mangle]
pub extern "C" fn rust_func() -> int {
return 1234444;
}
#[lang = "stack_exhausted"] extern fn stack_exhausted() {}
Regards,
Kashyap
