I'm using SDK 3rd and, probably I found a bug in Carbide, as it seems it can't compile a project as Ecom plugin.
In fact, it compile it putting .rss file in standard dll directory, not in plugin directory. Emulator, in these condition, doesn't load the plugin.
Codewarrior and gcce, instead, compile the project and put rss and all file in the right path, and Emulator can load it correctly.
I found this trying to compile and emulate Sip Example provided with SDK 3rd.
