Compile error related with Qcoreevent

Hi all,
I am trying an application on LINUX(SUSE 10.2) where I am using the external library (OCC) with the Qt application. But I am ending with compile time error:

Has anybody faced the similar kind of problem, what could be the solution for this?
Any suggestions are really welcome.
