This action lets you easily cross-compile Rust projects using cross.
Here's a simplified example from the test and release workflow for
my tool ubi:
jobs:
release:
name: Release - ${{ matrix.platform.release_for }}
strategy:
matrix:
platform:
- os_name: Windows-x86_64
os: windows-latest
target: x86_64-pc-windows-msvc
skip_tests: true
- os_name: macOS-x86_64
os: macOS-latest
target: x86_64-apple-darwin
# more targets here ...
runs-on: ${{ matrix.platform.os }}
steps:
- name: Checkout
uses: actions/checkout@v3
- name: Build binary
uses: houseabsolute/actions-rust-cross@v0
with:
command: ${{ matrix.platform.command }}
target: ${{ matrix.platform.target }}
args: "--locked --release"
strip: true
- name: Publish artifacts and release
uses: houseabsolute/actions-rust-release@v0
with:
binary-name: ubi
target: ${{ matrix.platform.target }}
if: matrix.toolchain == 'stable'This action takes the following parameters:
| Key | Type | Required? | Description |
|---|---|---|---|
command |
string (one of build, test, or both) |
no | The command(s) to run. The default is build. Running the test command will fail with *BSD targets and non-x86 Windows. |
target |
string | yes | The target triple to compile for. This should be one of the targets found by running rustup target list. |
working-directory |
string | no | The working directory in which to run the cargo or cross commands. Defaults to the current directory (.). |
toolchain |
string (one of stable, beta, or nightly) |
no | The Rust toolchain version to install. The default is stable. |
GITHUB_TOKEN |
string | no | Defaults to the value of ${{ github.token }}. |
args |
string | no | A string-separated list of arguments to be passed to cross build, like --release --locked. |
strip |
boolean (true or false) |
no | If this is true, then the resulting binaries will be stripped if possible. This is only possible for binaries which weren't cross-compiled. |
cross-version |
string | no | This can be used to set the version of cross to use. If specified, it should be a specific cross release tag (like v0.2.3) or a git ref (commit hash, HEAD, etc.). If this is not set then the latest released version will always be used. If this is set to a git ref then the version corresponding to that ref will be installed. |
Under the hood, this action will compile your binaries with either cargo or cross, depending on
the host machine and target. For Linux builds, it will always use cross except for builds
targeting an x86 architecture like x86_64 or i686.
On Windows and macOS, it's possible to compile for all supported targets out of the box, so cross
will not be used on those platforms.
If it needs to install cross, it will install the latest version by downloading a release using
my tool ubi. This is much faster than using cargo to
build cross.
When compiling on Windows, it will do so in a Powershell environment, which can matter in some
corner cases, like compiling the openssl crate with the vendored feature.
Finally, it will run strip to strip the binaries if the strip parameter is true. This is only
possible for builds that are not done via cross. In addition, Windows builds for aarch64 cannot
be stripped either.
You can use the Swatinem/rust-cache action with this one
seamlessly, whether or not a specific build target needs cross. There is no special configuration
that you need for this. It just works.
