Could not compile huffman about uncbv

[antoyo]

Which Rust version do you have (rustc -V)?

Which command did you run?
On which platform?

I cannot reproduce this issue with both Rust stable (1.14) and nightly on ArchLinux.

Thanks for reporting this issue.

rustc 1.7.0

Apologies command was cargo install --path . ,other command produces another error which I will post below.

This is a very old version, but I made the changes to make it work on it.
Please tell me if cargo install uncbv now works.

[JustinHadi]

All works now!
