Post the whole log here. With strings you've posted I can say what where is some unresolved external dependencies, to fix you need to resolve them ;)

By log did you mean the whole error message.

when you compile your project compiler shows you this error, right? I need the whole error, not just last lines...

Look like where is conflict between definitions of main... Do you use any libraries other than Qt's?

AcerExtensa

and you must use "main" as start point not windows equivalent like WinMain, wmain etc...

actually i was trying to make various subproject with one main function.

Make sure you projects not containing a main function are using a lib template, not app.
