Tommy,

you might need to flush the output to directly see stuff.
If you use std::cout and std::endl, that happens automatically.

Also, are you debugging through unit tests? Are you doing ctest -V?

We have this tutorial:

...but I admit it could be a bit longer. Perhaps you can add to this
page once you've figured out your problem?

Thanks,
