QNetworkConfigurationManager::capabilities() returning empty QFlags
-
I have two environments (DEV and PROD). Both are linux running Connman as network manager. In my DEV environment the signal QNetworkConfigurationManager::configurationAdded is working properly when I plug/unplug ethernet cable. On the other hand, in PROD env, with computer with the same hw specifications, this signal is not emitted. My question in this topic is: which it is based Qt, in particular QtNetwork, to emit this signal? What their depenedencies? I am assuming that I have any missing dependencies in PROD env by wich this is not working properly.
Checking QNetworkConfigurationManager::capabilities, the result in DEV environment is QFlags(0x1|0x10|0x20|0x40) while in PROD env is QFlags() (empty). So this can be a problem with QtNetwork backend in PROD env.

Hi,
Did you deploy the bearer plugins ?

Before diving deep in the Qt specific deployment stuff, how are you currently deploying/running your application to your prod machine ?

@SGaist All Qt libraries that I think are needed are in the same directory than my app executable or in SO path (/usr/lib64). Doing ldd against app binary, all libraries are found. What's libraries are needed to use QtBearer plugin? I think that your point about Qt Bearer plugin deploy is right but I don't know how to proceed with it.
Thanks in advance.

You have to deploy the bearer plugin folder.
Are you mixing your system Qt installation with the one you used to build your application ?

@SGaist just have deployed plugins folder into the same directory than binary with same result. I think I'm not mixing anything, all libraries installed in system are in /lib64 and deployed with app are in same dir. Need to do anything more in addition to copy plugins folder to binary dir?

What I find strange is that you are deploying things in several places.
Take a look at this excellent article about deployment.
There's also the deployment guide.

@SGaist I found the issue and you 're in the right way. Debuggin with QLibraryInfo::location(QLibraryInfo::PluginsPath) I've noticed that the path in this trace is not correct, in fact is the path where the machine wich build binary, have plugins directory, so I need to change this. Thanks a lot for your help and for this articles.

What did you change ?
