源码编译OpenEuler-StratoVirt过程&&遇到问题及其解决方案

环境

OpenEuler 操作系统

环境配置

安装rust环境

配置rust字节镜像链接

export RUSTUP_DIST_SERVER="https://rsproxy.cn"
export RUSTUP_UPDATE_ROOT="https://rsproxy.cn/rustup"

官方脚本

curl https://sh.rustup.rs -sSf | sh

配置环境变量到当前终端

source $HOME/.cargo/env

在~/.cargo/config文件写入，加速Crate.io

[source.crates-io]
replace-with = 'rsproxy'

[source.rsproxy]
registry = "https://rsproxy.cn/crates.io-index"

解决过程

报错原因应该是缺少libfdt
经过网上查询，类似这种错误cannot find -lxxx，都是缺少libxxx库，尝试执行

yum install libfdt

发现下载了dtc这个包，但是依旧编译不成功，这里还需安装dtc-devel包，

yum install dtc-devel

最终解决方案

也就是说解决note: /usr/bin/ld: cannot find -lfdt问题需要安装dtc和dtc-devel两个包

yum install dtc
yum install dtc-devel

随后编译成功

换yum源

为了提高yum速度，我更换了yum源。上述yum下载是在换源之后，可参考链接
