Question

我想在我的Ubuntu 16.04 Server Edition中以gcc版本8.1.0（Ubuntu 8.1.0-5ubuntu1〜16.04）正确安装和配置Intel TBB的最新稳定版本。我下载了用于Linux的TBB最新稳定版本：https://github.com/01org/tbb/releases/download/2018_U5/tbb2018_20180618oss_lin.tgz，然后按照此视频教程中给出的说明进行操作： https://www.youtube.com/watch?v=4nrDZjyIOXE我在此文件/home/marco/tbb2018_20180618oss/bin/tbbvars.sh的以下行中进行了修改：

#TBBROOT=SUBSTITUTE_INSTALL_DIR_HERE

进入

TBBROOT=/home/marco/tbb2018_20180618oss

然后，按照我执行的同一视频教程：

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

在主目录tbb2018_20180618oss中，我创建了一个测试目录，并用一个简单的test.cpp文件填充了该文件：

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

test.cpp在哪里：

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

int main() {
  return 0;
}

编译时，我得到了一些难以理解的警告列表，因为我实际上没有在test.cpp中放置任何内容：

我想念什么？如何解决问题？期待您的帮助。马可

可以安全地忽略警告。当前，TBB在C ++ 17中使用了一些不推荐使用的东西。我们将尝试在以后的版本中修复警告。

Ubuntu 16.04 gcc8中的Intel TBB：std :: uncaught_exception（）已弃用
