In order to obtain an executable file for a C++ program, the following instructions under Linux/Unix can be used

c++ -c -Wall myprogram.cpp
c++ -o myprogram myprogram.o

where the compiler is called through the command c++/g++. The compiler option -Wall means that a warning is issued in case of non-standard language. The executable file is in this case myprogram. The option -c is for compilation only, where the program is translated into machine code, while the -o option links the produced object file myprogram.o and produces the executable myprogram .

For Fortran2008 we use the Intel compiler, replace c++ with ifort. Also, to speed up the code use compile options like

c++ -O3 -c -Wall myprogram.cpp
