macOS Could not compile syntex_syntax v0.24.0

[piaojin]

Cargo.lock:
[[package]]
name = "rusty-cheddar"
version = "0.3.3"
source = "registry+https://github.com/rust-lang/crates.io-index"
dependencies = [
"clap 1.5.6 (registry+https://github.com/rust-lang/crates.io-index)",
"syntex_syntax 0.24.0 (registry+https://github.com/rust-lang/crates.io-index)",
"toml 0.1.30 (registry+https://github.com/rust-lang/crates.io-index)",
]

when I cargo build and then I will get following error:

error: to use a constant of type codemap::Span in a pattern, codemap::Span must be annotated with #[derive(PartialEq, Eq)]

error: Could not compile syntex_syntax.

"syntex_syntax 0.59.1" is ok. But rusty-cheddar use "syntex_syntax 0.24.0".

Hi @piaojin, as you can probably tell I don't really have the time to maintain this crate anymore unfortunately. I would strongly suggest looking into cbindgen instead.

Just to chime in that syntex_syntax v0.24.0 doesn't compile in windows-gnu either. cbindgen works though :)

Thanks for all the work so far.

@Sean1708 Thank you for your suggestion. I will try cbindgen.
