error compiling clap

[slowkow]

I'm having trouble building collapse. Could I please ask for help figuring this out?

A file wasn't found for an out-of-line module.

Erroneous code example:

```
mod file_that_doesnt_exist; // error: file not found for module

fn main() {}
```

Please be sure that a file corresponding to the module exists. If you
want to use a module named `file_that_doesnt_exist`, you need to have a file
named `file_that_doesnt_exist.rs` or `file_that_doesnt_exist/mod.rs` in the
same directory.

Hi! This looks like a build error within clap, which is not part of collapse, but a dependency that I don't have control over. 2.32.0 seems to be the newest version of clap, which I use for CLI parsing. Not sure what's going on. I'll try to reproduce it myself and report back.

[sdleffler]

I've pushed a new commit which fixes builds for me on Rust 1.29. The clap dependency here is set to use the newest clap published as long as it doesn't go over major version 2, so it may be that clap 2.32 does not want to compile on stable Rust 1.28 as the newest stable Rust version is actually 1.30.1. In any case it now compiles for me on 1.29 with the updates I just made. I'm going to update to 1.30.1 and see how it does.

[sdleffler]

Seems to work fine on newest stable Rust. I suggest updating your Rust installation and trying again. For what it's worth, I did not get the clap error compiling on Rust 1.29 - instead, the build failed when trying to compile the pbr dependency, which is the progress bar I used.

Since I believe the root cause of this issue is an outdated Rust installation, I'm going to close this issue. Please comment again if you're still having trouble.

[slowkow]

Thanks for the comments! I appreciate your help.

I did rustup update to update my rust to version 1.30.0

Then I did cargo build --release and got the same error as before:

   Compiling rand v0.3.22

Next, I tried removing clap and trying again. Now I get a new error, similar to the one you mentioned!

First, get rid of clap:

$ rm -rf /Users/slowikow/.cargo/registry/src/github.com-1ecc6299db9ec823/clap-2.32.0

Now try building again:

Worked for me using the latest nightly:

$ rustc --version
rustc 1.32.0-nightly (f1e2fa8f0 2018-11-20)
$ cargo --version
cargo 1.32.0-nightly (b3d0b2e54 2018-11-15)

[sdleffler]

@slowkow that looks like whatever is failing the build wants to be using Edition 2018. Can you try again using Rust nightly? If you're using rustup you can do rustup override set nightly to tell rustup to use nightly for a single project.

[sdleffler]

Er, the clap error looks that way. I can't speak for the second error.
