How compile a c++ complex folder with a simple command?

November 23, 2021

I have a many c++ files in a folder:

> project
  - a.cpp
  - a.h
  - b.cpp
  - b.h
  - main.cpp
  - .editorconfig
  - .gitignore

And use this command to compile my code:

g++ *.c* -o main

However I need organize my code in

> project
  > src
    > classes
      - a.h
      - b.h
    > methods
      - a.cpp
      - b.cpp
    - main.cpp

  - .editorconfig
  - .gitignore

Some questions:

1 – What command can I use to compile my project?
2 – Is it a good folder structure?

>Solution :

I would try to compile it with the following command:

g++ src/main.cpp src/methods/*.cpp -I src/classes -o myprogram

As long as your compilation times are reasonable, there is not much need to use a build system like Make yet.

I don’t know if it’s a good directory structure, but that’s a pretty subjective question. It’s more common to see directories named "include" or "header" than "classes", since it’s possible to have header files that do not define classes. I usually like to put all of the source files in the same directory unless there are a lot of them, or some are written by different teams.
