The Rust build system uses a Python script called `x.py` to build the compiler,
|
||||
which manages the bootstrapping process. It lives at the root of the project.
|
||||
|
||||
The `x.py` command can be run directly on most systems in the following format:
|
||||
The `x.py` command can be run directly on most Unix systems in the following format:
|
||||
|
||||
```sh
|
||||
./x.py <subcommand> [flags]
|
||||
```
|
||||
|
||||
This is how the documentation and examples assume you are running `x.py`.
|
||||
|
||||
Systems such as Ubuntu 20.04 LTS do not create the necessary `python` command by default when Python is installed that allows `x.py` to be run directly. In that case, you can either create a symlink for `python` (Ubuntu provides the `python-is-python3` package for this), or run `x.py` using Python itself:
|
||||
This is how the documentation and examples assume you are running `x.py`. Some alternative ways are:
|
||||
|
||||
```sh
|
||||
# Python 3
|
||||
python3 x.py <subcommand> [flags]
|
||||
# On a Unix shell if you don't have the necessary `python3` command
|
||||
./x <subcommand> [flags]
|
||||
|
||||
# Python 2.7
|
||||
python2.7 x.py <subcommand> [flags]
|
||||
# On the Windows Command Prompt (if .py files are configured to run Python)
|
||||
x.py <subcommand> [flags]
|
||||
|
||||
# You can also run Python yourself, e.g.:
|
||||
python x.py <subcommand> [flags]
|
||||
```
