Compiling C++-code without a file

Question

I\'m trying to compile some C++ code using your standard g++ compiler. However, rather than compiling from a file:

main.cpp:

#include 

        

Answer 1

How about popen("gcc -o -xc++ -", "w");? Gives you aFILE*` but the output goes straight into GCC.

BTW, there is no point in using the -Wall flag. That's for human consumption. In fact, -w -Wfatal-errors makes sense. Either it compiles or it doesn't.
