For belt and braces, is there a way to check for installed packages in C++ too so I can output an error message if a required package is not installed?
Yes, of course. You can try to see if the program exists - so you test for the program, not for the package. You can even try to run it asking for its version string, and decide if it is the correct one when it responds. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" (Minas Tirith))
