Hello,
I have a problem with users equipped with an old version of Windows
(8, or 7). The latest version of my app (Qt 5.11.1/MSVC 2017 based)
required QtBluetooth but when users load the app they get a message
saying:
"This Windows version does not support the required Bluetooth API.
Consider updating to a more recent Windows (10.0.10586 or above)"
Then they press OK and the app shuts down.
I understand the message and have no problem removing BT
functionalities for these users with old Windows versions, but my
question is: can I avoid to build several binaries, i.e. is there a
way not to load QtBluetooth if windows version is not recent enough ?
Any other suggestion ?
The message is shown when the dll is loaded, so unfortunately I only see
two other ways of working around the problem.
1) You could try to dlopen the library and lazy load all the
functionality you need. That would mean, that you have to resolve every
function though...
2) You could put your Bluetooth code into a plugin. If that fails to
load, the application will not exit immediately, but only the plugin
loading will fail then.
Thanks
Philippe.
