安装 CMake

  1. 安装gcc等依赖程序
    yum install -y gcc gcc-c++ wget

  2. 获取CMake源码包
    wget https://cmake.org/files/v3.23/cmake-3.23.2.tar.gz

  3. 解压并安装

    rpm --import https://packages.microsoft.com/keys/microsoft.asc
    sh -c 'echo -e "[code]\nname=Visual Studio Code\n
    baseurl=https://packages.microsoft.com/yumrepos/vscode\nenabled=1\ngpgcheck=1\n
    gpgkey=https://packages.microsoft.com/keys/microsoft.asc" > /etc/yum.repos.d/vscode.repo'
    yum check-update
    yum install code

  2. 下载 rpm 包安装
    复制链接下载最新 rpm 包：https://update.code.visualstudio.com/1.70.1/linux-rpm-x64/stable
    安装：rpm -ivh code-1.70.1-1660113182.el7.x86_64.rpm

启动 VSCode：

  1. 通过桌面程序启动
    1
  2. 通过终端启动

将源码通过 CMake 编译

  1. 打开源码文件夹
    4
  2. 点击 cmake 菜单栏，点击config project
    5
  3. config完成后会生成如下目录、再点击如图build生成二进制文件
