在docker里使用gcc-9 + tbb搭建CC++并行开发环境

在docker里使用gcc-9 + tbb搭建C/C++并行开发环境

通过vscode提供的远程开发插件，在MacOS里安装ubuntu的docker容器，并在容器中进行c/c++开发。记录环境配置过程：

1. 下载ubuntu 18.04 容器镜像（主机内）

   docker pull ubuntu:18.04
   
   docker run -idt --name ubdev --memory-swap=-1 ubuntu:20.04
   #设置swap参数是为了gcc-11的编译

2. 进入容器内

   docker exec -it ubdev /bin/bash

3. 安装依赖库（容器内）

   apt-get update
   apt install software-properties-common

4. 下载并安装gcc-9（容器内） 

   apt-get install software-properties-common
   add-apt-repository ppa:jonathonf/gcc
   apt-get update
   apt-get install gcc-9
   

5. 安装tbb

   wget https://github.com/intel/tbb/archive/2019_U8.tar.gz
   tar zxvf oneTBB-2019_U8.tar.gz
   mv oneTBB-2019_U8 tbb-2019_U8
   cd tbb-2019_U8
   
   
   
   cp build/linux.gcc.inc build/linux.gcc-9.inc 
   # 编辑build/linux.gcc-9.inc文件，可以拷贝到容器外面修改后在拷贝进来
   # 找到下面的语句修改改 g++-9 gcc-9
   CPLUS ?= g++-9
   ConLY ?= gcc-9
   
   #编译tbb
   make compiler=gcc-9 stdver=c++17 tbb_build_prefix=my_tbb_build
   
   #手动安装
   mkdir /usr/local/tbb-2019_U8
   cp -r include /usr/local/tbb-2019_U8/include
   ln -s /usr/local/tbb-2019_U8/include/tbb /usr/local/include/tbb
   cp -r build/my_tbb_build_release /usr/local/tbb-2019_U8/lib
    
   ln -s /usr/local/tbb-2019_U8/lib/libtbb.so.2 /usr/local/lib/libtbb.so
   ln -s /usr/local/tbb-2019_U8/lib/libtbbmalloc.so.2 /usr/local/lib/libtbbmalloc.so
   ln -s /usr/local/tbb-2019_U8/lib/libtbbmalloc_proxy.so.2 /usr/local/lib/libtbbmalloc_proxy.so
   echo 'export LD_LIBRARY_PATH=/usr/local/tbb-2019_U8/lib:$LD_LIBRARY_PATH' >> ~/.bashrc
   source ~/.bashrc

6. 打开vscode（主机内）
     
7. 编译task的参数如下

   {
       "tasks": [
           {
               "type": "cppbuild",
               "label": "C/C++: g++-9 build active file",
               "command": "/usr/bin/g++-9",
               "args": [
                   "-g",
                   "-std=c++17",
                   "${file}",
                   "-o",
                   "${fileDirname}/${filebasenameNoExtension}",
                   "-ltbb",
                   "-L /usr/local/lib"
               ],
               "options": {
                   "cwd": "${fileDirname}"
               },
               "problemMatcher": [
                   "$gcc"
               ],
               "group": {
                   "kind": "build",
                   "isDefault": true
               },
               "detail": "Task generated by Debugger."
           }
       ],
       "version": "2.0.0"
   }
