Hi @kkysen

Hi, what errors are you getting when you try to compile?

@kkysen ,

Thanks for the quick reply.

Earlier, I remember seeing complain of toolchain 1.65 was too old. but not this time.

Here is the errow message. Same as using "cargo install c2rust" approach

I'll look into that error in #1057, but I don't think there's anything wrong with the rust toolchain. Is there something I'm missing about the rust toolchain causing errors?

tjyang commented 5 months ago

Sorry, I can't re-produce this toolchain being too old when compiling the crates. Please look at this issue https://github.com/immunant/c2rust/issues/1059 I am closing this issue.
