main.rs is unable to compile

[coder543]

When running make, it spits out this error message.

rustc -O --target i386-intel-linux --lib -o main.o -c main.rs
error: no item found for `ty_desc`
error: no item found for `opaque`
error: no item found for `ty_visitor`
error: no item found for `freeze`
error: no item found for `send`
error: no item found for `closure_exchange_malloc`
error: aborting due to 6 previous errors
make: *** [main.o] Error 101

It seems dependent on some part of the rust runtime? maybe?

I'm running rustc version 0.7

rustc 0.7
host: x86_64-apple-darwin

any tips you can give?

It seems that new lang items were added and some were renamed. For example:
https://github.com/thestinger/rust/commit/4a29d6eb3f20c2b7a05bb9c9c2f964da606e39ca
rust-lang/rust#6962

Here's a quick fix. Some parts may be excessive.

@pczarn if you open a PR for that commit I'll merge it

[coder543]

Thanks! with these changes, it now compiles and runs!

But I'm curious, do these feature implementation stubs negatively impact Rust in any way? closure_exchange_malloc in particular seems important to not be stubbed out... but I'm new to this whole Rust thing, so I'm not an expert by any means.

[pczarn]

I'm not an expert either. To begin with, malloc is unimplemented anyway. I think we don't use features that may require dynamic allocation.
