Question

I am using gcc on linux to compile C++ code.
There are some exceptions which should not be handled and should close program.
However, I would like to be able to display exception string:

For example:

throw std::runtime_error(" message"); does not display message, only type of error.
I would like to display messages as well.
Is there way to do it?

it is a library, I really do not want to put catch statements and let library user decide.
However, right now library user is fortran, which does not allow to handle exceptions.
in principle, I can put handlers in wrapper code, but rather not to if there is a way around

Standard exceptions have a virtual what() method that gives you the message associated with the exception:

int main() {
   try {
       // your stuff
   }
   catch( const std::exception & ex ) {
       cerr << ex.what() << endl;
   }
}
