This time I am trying to run a c++ program named epa in Linux using cmd but this time time , I am facing some errors.

Last time ,
I ran the epamain.cpp using

Код: Выделить всё

icpx -I../../include epamain.cpp -o epamain

and ran successfully,
when I ran now, I received 14 errors,
changing the version of c++ now gives me three errors only.

Код: Выделить всё

icpx -std=c++11 -I../../include epamain.cpp -o epamain 

I don't want to change the code, since it is an old project.
I want to run it like before but wonder about the errors(still 3 errors) as above show up:
