# Usage:
|
|
# CARGO_BUILD_TARGET=<target> cargo.sh <args>...
|
|
#
|
|
# This script wraps `cargo` invocations, and calls either `cargo`
|
|
# or `cross`, as appropriate. It checks the value of the
|
|
# `CARGO_BUILD_TARGET` environment variable, and calls `cargo` if
|
|
# the target matches the host target, and `cross` otherwise.
|
|
#
|
|
# Use of `cargo`/`cross` can be forced by setting the `CARGO`
|
|
# environment variable to `cargo`/`cross`. This is useful for
|
|
# instance to force the use of `cross` in CI even for the host
|
|
# target.
|
|
#
|
|
# When cross is used, the target directory will be appended
|
|
# `cross-<target>` to avoid libc conflicts in host binaries (e.g.,
|
|
# build scripts, proc macros). The computed value of the target
|
|
# directory can be obtained with `cargo.sh --print-target-dir`.
|
|
#
|
|
# Lastly, when using `cross` this scrips sets some configuration
|
|
# to allow running `youki` tests inside the `cross`` container.
|
|
# Please check the comments in this scrips to learm more about that.
|
|
#
|
|
# Limitations:
|
|
# * You **must** use the `CARGO_BUILD_TARGET` environment variable
|
|
# to specify the build target instead of using the `--target` CLI
|
|
# argument, or a configuration file like `.cargo/config.toml`.
|
|
# * If **must** use the `CARGO_TARGET_DIR` environment variable to
|
|
# specify the target directory instead of using the `--target-dir`
|
|
# CLI argument, or a configuration file like `.cargo/config.toml`.
