Error while installing

[palnabarun]

I am new to rust and I wanted to generate the epub format ebook for my kindle.

I downloaded the project to rebuild the book the second edition draft. When I do cargo run --release, I encounter the following error:

nabarun@pal:~/codesl/trpl-ebook (git:master) $ cargo run --release

error: Could not compile `rustc-serialize`.

error: build failed

I tried to search and debug the error but couldn't do so owing to my lack of knowledge of rust at the moment. Did anyone else encounter this error?

Thanks @shepmaster for cross-referencing the posts.

Can you run cargo update (to try and get the latest versions of the dependencies) and see if this fixes the build?

Cross-posting my answer:

rustc-serialize 0.3.19 was released on April 4, 2016. It includes the syntax:

fn read_enum_struct_variant_field<T, F>(
    &mut self,
    &f_name: &str, // This is no longer allowed
    f_idx: usize,
    f: F,
) -> Result<T, Self::Error>;

This syntax was erroneously allowed until Oct 21, 2016 (Rust 1.14.0) when it was turned into a warning. On Nov 4, 2017 (Rust 1.23.0), this became an error.

The solution is to update the version of rustc-serialize.

@killercup the real fix would be to move away from rustc-serialize, but I'm guessing you know that ;-).

[palnabarun]

Well, it worked but cropped up another issue which according to me is a different thread altogether

Thanks @shepmaster for the help.

@shepmaster the real fix would be to move this functionality into mdBook, but I'm guessing you know that ;-).

[shepmaster]

Seems like this issue should remain open until the master branch has been updated?

[killercup]

Indeed!

@palnabarun can you open a PR that updates the Cargo.lock file so the project compiles again?

[palnabarun]

Sure. @killercup
