Re: [rust-dev] Cargo multiple targets
The links for FAQ and Manifest Format on http://crates.io should be rearranged to be at the top of the homepage...instead of the bottom, in my opinion.

[rust-dev] Cargo multiple targets
Hello Rust folks! I am using Cargo and I am trying to specify mulitple targets in my Cargo.toml file. First of all is this even possible? The way I have set things up is that I have src/hmwhoami.rs which builds to a binary, and uses src/proof.rs and that builds totally fine. My Cargo file looks like this: [package] name = hmproof version = 0.1.0 authors = [ i...@houstonmedia.se ] [[bin]] name = hmwhoami [dependencies.rust-http] git = https://github.com/chris-morgan/rust-http.git; Now what I also want to do is to build src/proof.rs as a library (that is linkable with C programs so they can call the extern fn's). My initial approach was this: [package] name = hmproof version = 0.1.0 authors = [ i...@houstonmedia.se ] [[bin]] name = hmwhoami [[lib]] name = proof (I also tried adding a path) path = src/proof.rs [dependencies.rust-http] git = https://github.com/chris-morgan/rust-http.git; I also tried putting the [[lib]] part after the dependencies part. The error I get is this: error: couldn't read src/bin/hmwhoami.rs: couldn't open file (no such file or directory (No such file or directory); path=src/bin/hmwhoami.rs; mode=open; access=read) Whiich doesn't make any sense at all to me. Why does it suddenly start looking in src/bin? Do I have to put my bin code in src/bin and my lib code in src lib or what? That would probably break the hmwhoami executable because I'd have to make the proof library an extern crate, at least I think I would have to do that. Thanks!

Hi, Isak! According to manifest documentation [1] you can specify crate type (dynamic or static lib or rlib) using crate_type option: [[lib]] … crate_type = [dylib, staticlib] The above configuration should build you both .a and .so files.
