我正在尝试使用 meta-rust 层将 rust 与
bitbake/yocto一起使用。
在图层本身中，我可以看到最近添加了 cargo 版本 1.58.0 的配方。不幸的是，当我尝试使用 BitBake 构建任何 rust 代码时，我收到以下错误：

rust 代码在本地系统上构建良好，我相信错误是因为 yocto 使用的 cargo 版本是 1.54
tmp/work/corei7-64-poky-linux/libstd-rs/1.54.0-r0/recipe-sysroot-native/usr/bin/cargo --version
cargo 1.54.0
如何让yocto使用更高版本的cargo？食谱存在于
meta-rustbitbake -s | grep cargo
cargo :1.58.1-r0
cargo-cross-canadian-x86-64 :1.58.1-r0
cargo-native :1.58.1-r0 :1.54.0-r0
nativesdk-cargo :1.58.1-r0
注意是否已设置

这表明它默认为版本1.54.0
注意：
bitbake -c cleanall rust cargoERROR: Nothing PROVIDES 'rust'
rust was skipped: Rust recipe doesn't work for target builds at this time. Fixes welcome.
这通常是通过 PREFERRED_VERSION_foo 在 bitbake 中完成的，它看起来像 meta-rust 包含一个可以为您进行此更改的文件：
RUST_VERSION ?= "1.58"
如果您将此文件包含在您的distro.conf（或local.conf）中并更改第4行以匹配版本1.58，您应该能够使用/构建货物版本1.58
您仍然可以在 local.conf 上手动更改
PREFERRED_VERSION_cargo/rust*ah008a 在评论中正确指出，除了设置 RUST_VERSION 之外，还必须包含
rust_versions.inc。该文件设置默认值，然后将 Rust 版本传播到其他 Rust 工具，例如 Cargo：
# include this in your distribution to easily switch between versions
# just by changing RUST_VERSION variable
RUST_VERSION ?= "1.78.0"
PREFERRED_VERSION_cargo ?= "${RUST_VERSION}"
PREFERRED_VERSION_cargo-cross-canadian-${TARGET_ARCH} ?= "${RUST_VERSION}"
PREFERRED_VERSION_cargo-native ?= "${RUST_VERSION}"
PREFERRED_VERSION_nativesdk-cargo ?= "${RUST_VERSION}"
PREFERRED_VERSION_libstd-rs ?= "${RUST_VERSION}"
PREFERRED_VERSION_nativesdk-libstd-rs ?= "${RUST_VERSION}"
PREFERRED_VERSION_rust ?= "${RUST_VERSION}"
PREFERRED_VERSION_rust-cross-canadian-${TARGET_ARCH} ?= "${RUST_VERSION}"
PREFERRED_VERSION_rust-tools-cross-canadian-${TARGET_ARCH} ?= "${RUST_VERSION}"
PREFERRED_VERSION_rust-cross-${TARGET_ARCH} ?= "${RUST_VERSION}"
PREFERRED_VERSION_rust-cross-${DEFAULTTUNE}-${TCLIBC} ?= "${RUST_VERSION}"
PREFERRED_VERSION_rust-crosssdk-${SDK_ARCH}-${TCLIBC} ?= "${RUST_VERSION}"
PREFERRED_VERSION_rust-llvm ?= "${RUST_VERSION}"
PREFERRED_VERSION_rust-llvm-native ?= "${RUST_VERSION}"
PREFERRED_VERSION_rust-native ?= "${RUST_VERSION}"
覆盖
RUST_VERSIONdistro.conflocal.confRUST_VERSION = 1.82.0
require ${SRC_DIR}/meta-rust/conf/distro/include/rust_versions.inc
当然可以根据需要更改路径。
这是ah008a说的，我只是想整合一下他们提供的信息。
