in C++11 which is now default in GCC 6, shared_ptr has a bool operator that returns if the shared_ptr is a null pointer,
so the return type is not bool anymore. use an expression to return bool type, eg:

- bool loaded = LoadPlugin(pluginName, argc, argv);
+ bool loaded = (LoadPlugin(pluginName, argc, argv) != nullptr);

fixed in https://build.opensuse.org/request/show/407093

This has been fixed now in the network repository, but as far as I can tell licq has been meanwhile removed from Factory, so I cannot submit the package further.
