What is the proper way to track my build versions in Qt?

Question

Basically what I need in my project is a number of some sort that iterates itself every time I build my project, and that I can output by my program.

So for example, when generating audio, I need to add metadata that states that this audio file was generated by build #1551. After I build again, that number should go to #1552.

What is the proper way to do this in Qt?

Answer 1

Proper way is:

• Have (any possible) Version Control in your project (and forever for all projects)
• Instead of rather useless autoincremented counter use any id, provided by VCS of choice
• Get this id and output it (Mercurial sample, another SCMs just use another commands in $$system call)as any other variable
