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:

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

First, you'll want to check out this repository

git clone --recursive https://github.com/rust-lang/cargo
cd cargo

If you already have rustc and cargo installed elsewhere, you can simply run

cargo build --release

Otherwise, if you have rustc installed and not Cargo, you can simply run:

./configure
make
make install

If, however, you have neither rustc nor cargo previously installed you can run:

python -B src/etc/install-deps.py
./configure --local-rust-root="$PWD"/rustc
make
make install

Note: if building for 32 bit systems run BITS=32 python -B ..

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. To view the rendered version of changes you have made locally, run:

./configure
make doc
open target/doc/index.html

Release notes

High level release notes are available as part of Rust's release notes.
