can not build with rust 1.2.0

after i run

cargo build

it shows the compiler errors

src/vm.rs:144:30: 144:36 error: illegal suffix `u` for numeric literal

maybe we can rewrite the vm

after fixed some illegal suffix 'u' for numeric literal issues i found the execute macro is the real problem

Thank you for your interest. Unfortunately, this tree has not been updated by us in over a year. As stated in the README, you need a Rust compiler nightly from roughly around a year ago (August 2014) to build this project. Much has changed in the Rust language since, and it would require more work than fixing a macro to make this build on stable Rust: Dealing with the rename of {int,uint} to {isize,usize}, switch to the rustc serialize crate, using wrapped integer arithmetic in some places etc.

However, while this could be done, we probably won't take the time to update this repository to a newer version of Rust any time soon. In fact, we are uncertain about the Rust version and are currently rewriting the virtual machine in C, as it allows us to make better use of the Memory Pool System garbage collector, see clojit-cvm for an early prototype.

Just to add to gandro, we are always arguing if we should keep doing Rust of switch to C. Both have some major advantages and massiv drawbacks.

I am currently more focused on makeing the C VM. I would like to have it at least as far as this version written in rust is.

In the project rust-mps-obj (https://github.com/clojit/rust-mps-obj ) we have tried to make the Memory Pool System work together with Rust and build a nice abstraction around the Unsafe parts. In theory this could all work really well but we encounter a lot of practical problems.
