Tor,
Thanks for your reply. I’m still using QMake
After a long time debugging I have realised that there is some kind of magic
involved in using QPermission api.
I have found a qmake script that seems to look at Info.plist and search for the
necessary key: qtbase/mkspecs/features/permissions.prf
Also, it seems that a QT_PLUGIN must be set in qmake in order to link the
appropriate plugin.
But this is not stated anywhere in the documentation therefore I’m linking the
plugin manually:
LIBS +=
/Users/nsantos/Qt/6.6.3/macos_static/plugins/permissions/libqdarwincamerapermission.a
And I’m registering the plugin manually using:
Q_IMPORT_PLUGIN(QDarwinCameraPermissionPlugin)
When running the program I don’t have the same message anymore but it is still
complaining about the key not being on the Info.plist when it is.
checking permissions Qt::PermissionStatus::Undetermined
qt.permissions: Requesting QCameraPermission requires
"NSCameraUsageDescription" in Info.plist
The application is code signed with the camera entitlements:

What am I missing?
Thanks!
