Build failure

[tromey]

I tried building this today but it failed.

   Compiling rustc_codegen_gcc v0.1.0 (/home/tromey/Rust/rustc_codegen_gcc)
error[E0463]: can't find crate for `rustc_ast`
  --> src/lib.rs:18:1
   |
18 | extern crate rustc_ast;
   | ^^^^^^^^^^^^^^^^^^^^^^^ can't find crate

error: aborting due to previous error

I'm not sure if this is something I did wrong or not.

You might need rustc-dev:

rustup component add rustc-dev

Edit: Err, that should be done automatically by the prepare.sh script.

How did you try to build it?

I must have forgotten prepare.sh because I re-ran it, and now it is building. Sorry about that! I really thought I had done that.
