Building on a Unix-like systemĬlone the source with git: git clone https :// github. Otherwise, you'll need LLVM installed and llvm-config in your path. On tier 1 or tier 2 with host tools platforms, you can also choose to download LLVM by setting llvm.download-ci-llvm = true.

libstdc++-static may be required on some Linux distributions such as Fedora and Ubuntu.

ninja, or GNU make 3.81 or later (Ninja is recommended, especially on Windows).

g++, clang++, or MSVC with versions listed on LLVM's documentation.

If building LLVM from source, you'll need additional tools: To build Cargo, you'll also need OpenSSL ( libssl-dev or openssl-devel on most Unix distros).

libiconv (already included with glibc on Debian-based distros).

pkg-config if you are compiling on Linux and targeting Linux.

A C compiler (when building for the host, cc is enough cross-compiling may need additional compilers).

Make sure you have installed the dependencies: More information about x.py can be found by running it with the -help flag or reading the rustc dev guide. py # You can also run Python yourself, e.g.: Some alternative ways are: # On a Unix shell if you don't have the necessary `python3` command. This is how the documentation and examples assume you are running x.py.

The x.py command can be run directly on most Unix systems in the following format. The Rust build system uses a Python script called x.py to build the compiler, which manages the bootstrapping process. If you wish to contribute to the compiler, you should read CONTRIBUTING.md instead. Note: this README is for users rather than contributors. It contains the compiler, standard library, and documentation. This is the main source code repository for Rust.
