Alex Crichton 70152d8003 Only compile activated optional dependencies
Development dependencies are traversed during the resolution process, causing
them to be returned as the list of dependencies for a package in terms of
resolution. The compilation phase would then filter these out depending on the
dependency's transitivity, but this was incorrectly accounted for when the
dependency showed up multiple times in a few lists.

This commit fixes this behavior by updating the filtering logic to ensure that
only activated optional dependencies (those whose feature names are listed) are
compiled.

Closes #1805

Cargo downloads your Rust projects dependencies and compiles your project.

Installing Cargo

Cargo is distributed by default with Rust, so if you've got rustc installed locally you probably also have cargo installed locally.

If, however, you would like to install Cargo from the nightly binaries that are generated, you may also do so! Note that these nightlies are not official binaries, so they are only provided in one format with one installation method. Each tarball below contains a top-level install.sh script to install Cargo.

Note that if you're on Windows you will have to run the install.sh script from inside an MSYS shell, likely from a MinGW-64 installation.

Compiling from Source

Cargo requires the following tools and packages to build:

  • rustc
  • python
  • curl (on Unix)
  • cmake
  • OpenSSL headers (only for Unix, this is the libssl-dev package on ubuntu)

Cargo can then be compiled like many other standard unix-like projects:

git clone https://github.com/rust-lang/cargo
cd cargo
python src/etc/install-deps.py
./configure --local-rust-root="$PWD"/rustc
make
make install

More options can be discovered through ./configure, such as compiling cargo for more than one target. For example, if you'd like to compile both 32 and 64 bit versions of cargo on unix you would use:

$ ./configure --target=i686-unknown-linux-gnu,x86_64-unknown-linux-gnu

Adding new subcommands to Cargo

Cargo is designed to be extensible with new subcommands without having to modify Cargo itself. See the Wiki page for more details and a list of known community-developed subcommands.

Contributing to the Docs

To contribute to the docs, all you need to do is change the markdown files in the src/doc directory.
