我想在我的 Ubuntu 16.04 服务器版和 gcc 版本 8.1.0 (Ubuntu 8.1.0-5ubuntu1~16.04) 中正确安装和配置 Intel TBB 的最新稳定版本。我下载了 Linux 版 TBB 的最新稳定版本：https ://github.com/01org/tbb/releases/download/2018_U5/tbb2018_20180618oss_lin.tgz ，然后按照本视频教程中的说明进行操作： https://www。 youtube.com/watch?v=4nrDZjyIOXE我在这个文件/home/marco/tbb2018_20180618oss/bin/tbbvars.sh 中修改了这一行：

#TBBROOT=SUBSTITUTE_INSTALL_DIR_HERE

进入

TBBROOT=/home/marco/tbb2018_20180618oss

然后，按照我执行的相同视频教程：

marco@PC:~/tbb2018_20180618oss/bin$ . ./tbbvars.sh intel64
marco@PC:~/tbb2018_20180618oss/bin$

在主目录 tbb2018_20180618oss 我创建了一个测试目录并用一个简单的test.cpp文件填充它：

marco@PC:~/tbb2018_20180618oss/test$ nano test.cpp

在哪里test.cpp：

#include <tbb/tbb.h>
#include <tbb/parallel_for.h>

int main() {
  return 0;
}

编译我得到了一个不太容易理解的警告列表，因为我实际上并没有把任何东西放进去test.cpp：

可以安全地忽略这些警告。目前，TBB 在 C++17 中使用了一些不推荐使用的东西。我们将尝试在未来的版本中修复警告。
