Hi, I'm trying to make a really really simple hello world program in Rust using a custom library through Cargo, and I'm getting the error:

Could not compile `rstest`.

I have a lib rstestlib, containing a lib.rs with this inside it:

pub fn test() {
    println!("Test");
}

And the rstest program has a main.rs with:

extern crate rstestlib;
fn main() {
    rstestlib::test();
}

The rstest program has this as a Cargo.toml file:

[package]
name = "rstest"
version = "0.0.1"
authors = ["GravityScore <[email protected]>"]

[dependencies.rstestlib]
path = "../rstestlib"

And the rstestlib program has this as a Cargo.toml:

[package]
name = "rstestlib"
version = "0.0.1"
authors = ["GravityScore <[email protected]>"]

I've just reinstalled rust using the 1 line console command from the Cargo website. The output of rustc -v is rustc 0.13.0-nightly (0a5e7f359 2014-11-03 23:16:55 +0000). I've had this problem for a while now, and it's really disappointing because I love rust so much, but I can't use it at all anymore.

I've tried running ranlib target/deps/librstestlib* as some internet sources (eg. here) suggest, but when I do this I get a bunch of undefined symbols for architecture, and a note saying the .rlib file was not built for the current architecture I'm trying to build for (which is x86_64):

But, if I run lipo -info target/deps/librstestlib*, it says the archive file was built for x86_64:

input file target/deps/librstestlib-1806f5315b450877.rlib is not a fat file
Non-fat file: target/deps/librstestlib-1806f5315b450877.rlib is architecture: x86_64

This happens with any library I try and link, ones from GitHub or locally. I'm running OSX Yosemite (10.10), with the latest Xcode (6.1) and OSX SDKs installed. I get the same problem if I bypass Cargo and compile using rustc directly as well, so it's not a Cargo problem. I used the command rustc -L"../rstestlib/target" src/main.rs.

Does someone know what's going on here? I'm really stuck and can't figure out why this is happening. I really love Rust and really appreciate all the hard work that's gone into making it - it is fantastic. But it's not working at the moment, which is really disappointing and very limiting if I can't link against libraries.

[alexcrichton]

Hm, this seems odd. To get a handle on what's going on here, could you try compiling with rustc manually instead of using cargo? (would also help minimize). Something like this should do the trick:

$ rustc rstestlib/src/lib.rs --crate-name rstestlib --crate-type rlib
$ rustc rstest/src/lib.rs -L .

[benanders]

Unfortunately that still fails. Here's the exact output:

[benanders]

So I came across this: tpoechtrager/osxcross#11 which is someone having the exact same problem for something else, mentioning that the default archiver isn't sufficient and that x86_64-apple-darwin1X-ar needs to be used. I'm not entirely sure what this means, but does this help in any way?

[benanders]

I just tried to build Rust from the source, and I also get a bunch of file was built for archive which is not the architecture being linked errors:

Is this best off in a separate issue?

I also just downloaded Rust 0.12 rather than the latest nightly, and I get the same error, so it's something environmental causing it, not Rust itself. Any ideas anyone? I'm a bit desparate now.

[benanders]

So this turns out to be a completely environmental issue. There were a bunch of duplicate files of system programs (like ls, mv, etc...). Removing them got rust to work again!
