Intel TBB in Ubuntu 16.04 gcc8: std::uncaught_exception()’ is deprecated

I would like to properly install and configure the latest stable release of Intel TBB in my Ubuntu 16.04 Server Edition with gcc version 8.1.0 (Ubuntu 8.1.0-5ubuntu1~16.04). I downloaded the latest stable release of TBB for linux : https://github.com/01org/tbb/releases/download/2018_U5/tbb2018_20180618oss_lin.tgz and then, following the instructions given in this video tutorial: https://www.youtube.com/watch?v=4nrDZjyIOXE I modified in this file /home/marco/tbb2018_20180618oss/bin/tbbvars.sh this line:

#TBBROOT=SUBSTITUTE_INSTALL_DIR_HERE

into

TBBROOT=/home/marco/tbb2018_20180618oss

And then, following the same video tutorial I executed:

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

Within the main directory tbb2018_20180618oss I created a test dir and filled it with a simple test.cpp file :

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

Where test.cpp is :

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

int main() {
  return 0;
}

Compiling I got a list of warnings which are not really understandable, since I didn't put anything actually in test.cpp :

What am I missing? How to solve the problem? Looking forward to your kind help. Marco

The warnings can be safely ignored. Currently, TBB uses some deprecated stuff in C++17. We will try to fix warnings in future releases.
