Custom Plugin Trouble

[stevey]

Hi,

I'm trying to create a custom plugin using the QtPlugin framework.
I have 3 projects, a main Ui app, a "core" dll containing my plugin interface and an implementation of the plugin in another dll.

I'm getting the following compile errors in Qt Creator:

Starting: C:/Qt/2009.03/mingw/bin/mingw32-make.exe -w
mingw32-make: Entering directory `D:/Development/QtTests/TestPlugin1'

Exited with code 2.
Error while building project TestPlugin1
When executing build step 'Make'

I think it's to do with vtables and such, but I'm not sure how to fix the problem.
I've set the following varialbes in TestPlugin1.pro:

INCLUDEPATH += ../TestAppCore
LIBS += -L../TestAppCore/debug -lTestAppCore

INCLUDEPATH += ../TestAppCore
LIBS += -L../TestAppCore/debug -lTestAppCore

To copy to clipboard, switch view to plain text mode 

Can someone please point out what's probably completely obvious?
I've attached the 3 projects to this thread.


Thanks,

Stephen York
