Hi! I'm trying out rust for the first time, and successfully compiled and
installed rustc. I hit this error attempting to compile "hello world":
> ~ % cat hello.rs
> use std;
> fn main(args: [str]) {
> std::io::println("hello world from '" + args[0] + "'!");
> }
> ~ % rustc hello.rs
> hello.rs:1:0: 1:0 error: can't find crate for 'core'
> hello.rs:1 use std;
> ^
Googling turned up a possible problem of not running "make all" before "make
install"
<https://mail.mozilla.org/pipermail/rust-dev/2011-December/001158.html>, but
make all does nothing for me, so everything looks built. "make check" passes
fine.
This happens to me with both the 0.1 tarball and a github clone from Feb 5 2012
(91b6dc5c8ed8d839006de4ea6a7e8cd6727db93d). Platform is Mac OS X 10.6.7. Any
clues?
Perhaps relatedly, cargo looks like it's complaining alot. "cargo init" warns
about "warning: signature verification failed for sources.json", but finally
appears to do something if I run it from src/cargo/ (where sources.json is).
"cargo sync" then passes, but any "cargo install" commands immediately fail
with the same error; e.g.
> ~ % cargo install sqlite
> warning: Malformed source json: erickt (missing description)
> warning: Malformed source json: erickt (missing description)
