What happens here is that you installed one of the public demos, which are activated for one site identifier, whereas the SDK you have received produces binaries that are activated for another site identifier (the site identifier is an alphanumerical code assigned to every customer).
FYI, on OS X the currently activated site identifier is stored as the SiteId key in a plist (property list) file. You can use the builtin plutil tool to look it up:
The SDK you have received is activated for it.unige_1.0, which I guess is different from what you’ll get above.
The easiest thing you can do to solve this issue is perform the automatic activation (menu Settings -> Activate) from one of the packages specific to your own site identifier, that you have received together with the SDK.
OK now it works, i go back to the step : cd …/bin ./Qpepper new SaltPepper
and now there are no problems.
But When i come back to Qt creator and i build the project there is another problem as i show you in this image:
