How to feed the compiler code through QProcess?

Question

Qt

Somehow I was told instructions on how to build a compiler into my program, and there was one item called

Feed compiler code from file

So here's how to do it?
Because I searched, didn't find it, moved on to another part of the program, and now I'm back to the compiler again.

Answer 1

Hm, I think that was my answer.
For simplicity, just save the code to a file and run the compiler in a separate process, specifying the necessary switches and the path to the saved file with the code.
GCC can save error output to a file that you can read and output to the user.
This is somewhat inelegant, but simple and working way.
