Hi folks,
I am using XCode for Qt4.4 projects and linking my application with
multiple static (my own) libraries. In this construct, Main application
uses some of the libraries directly and those libraries uses other ones.
I get Undefined Symbols error while linking sub libraries to this
application.
I have already gone through the mailing list archives and tried the
following solutions:
(1) Linking all libraries with their sub libraries in pro file so that
application knows which library to be linked with.
(2) Linking single library Multiple times in main application pro file
such that it always knows the order of linking.
None of the above solution works. I tried linking these libraries in
other applications and they only work if a library is not calling some
function from other library. I then got the temporary solution of
creating and deleting objects of each library classes in my main
application before starting real functionality. Can anyone help me
finding the logical solution to this problem?
Regards,
Manoj
