Plugin compiler error: undefined reference

[FinderCheng]

I don't think so. Do you have ui.lib file generated with ui.dll. I'm not sure if DESTDIR works with it so check in debug folder. This ui.lib is the right file to link with while compiling and ui.dll it the right file to link with in runtime. And the previous syntax was okay - I use it on both - Windows and Linux.

Sorry, I check both DESTDIR and debug folders and there is no such file called ui.lib.

Are you sure? You are qmaking and building test.pro or app.pro?

Yes, I rebuild project with test.pro and app.pro each time and there is no error.

Open VS command prompt, go to the app dir and run:

qmake && nmake

qmake && nmake

To copy to clipboard, switch view to plain text mode 

and see what you get.

I'm sorry but I have no VS compiler. So I open app.pro as a separate project and build it, nothing wrong here.

Use Dependency Walker to check library dependencies of your app.exe. And did you try also running it from outside of QtCreator just by double clicking test.exe?

I have a little trouble with Dependency Walker. What results should I looking for? I checked test.exe(not app.exe, TARGET = test in app.pro) and its library contains ui.dll. And I tried to open test.exe outside QtCreator, no window opened...
