Unable to compile c++ code in Fedora linux

[Saurabh_Pradhan]

Hi,

I am unable to compile the following  c++ code. 

#include <iostream>
int main ()
{
        std::cout<<"Hello world !" <<std::endl ; 
        return 0 ; 
}

gcc version 8.0.1 20180131

icpc version 18.0.1 

Compilation Error :

Hi,

Seems like GCC version you have installed isn't supported by ICC 18.0.

Hello,

   if you add the "-ansi" option, it will compile.

Thanks. That actually worked.

You need to install the GCC version is not supported by ICC 18.0. You can download the supported GCC version from rocketmail tech support. Then, you can run any C++ code to that supported GCC without compilation error.

#include <iostream>
int main ()
{
        std::cout<<"Hello world !" <<std::endl ; 
        return 0 ; 
}

add the "-ansi" option
