使用Yocto的强制货版

Question

我正在尝试使用锈菌和bitbake/yocto使用meta-rust层。

在该层内部，我可以看到最近添加了cargo版本1.58.0的配方。不幸的是，当我尝试使用锈迹代码构建BitBake时，我得到了以下错误：

NOTE: Executing Tasks

锈蚀代码在本地系统上建立良好，我相信错误是因为yocto使用的货运版本为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cargo的最新版本？菜谱存在于meta-rust中，我可以看到yocto通过

bitbake -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，如果设置了RUSTVERSION ?= "1.58"，我会收到以下警告：

WARNING: preferred version 1.58 of cargo-native not available (for item cargo-native)
WARNING: versions of cargo-native available: 1.54.0

表示它默认为1.54.0版本。

注意：bitbake -c cleanall rust cargo会产生以下错误：

ERROR: 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foo在bitbake中完成的，它看起来像是元锈包含了一个为您做此更改的文件：

versions.inc#L4

RUST_VERSION ?= "1.58"

如果将此文件包含在distro.conf (或local.conf)中，并将第4行更改为与版本1.58匹配，则应该能够使用/构建货物版本1.58

您仍然可以在您的PREFERRED_VERSION_cargo/rust*上手动更改local.conf，但是您必须对所有生锈组件进行手动更改，就像rust_versions.inc文件所做的那样。
