[Interest] Application Plugins

[Graham Labdon]

Hi thanks for your reply
I have stepped through the code with the debugger and it reports that the specified module could not be found
This project succeeds if compiled in Release mode but not in Debug mode

Does anyone have clue about this?

Thanks

The only way I have found that it's possible to debug this is to singlestep through the Qt plugin loader code.

One problem that I've seen multiple times in the Qt 4 (don't know if this is fixed in 5) is that if I have run the application in debug mode, the plugin system stores a list of known plugins in the config. So when I switched to debug, it still tries to load the debug plugin and that won't work. After deleting the file with the cache list, I could load the plugin.

Sorry that I can't be of more help. Fire up the debugger :(

Bo.
