Debug output in a C++ library

[SteMMo]

Hi all,
I'm developing a pure C++ static library.
This library is linked to a Qt application.
How can I generate debug messages in the library?
I'm developing with VS environment in Windows and VSCode on iOS.

I'm trying with cout <<"xyz" and printf() but they are not shown in Debug window..

Thanks!
Regards

Redirect the stdout somewhere else such as a pipe or even just a file and read from there in the your Qt app.

But you could also create an abstration for IO that your library uses and then your Qt host applicadtion can just implement it. Easier.
