Error while trying to run a release build of a Qt application on Windows

I'm trying to build the Windows version of my app. The program compiles and runs fine on Qt Creator but when I try to run it standalone it throws the following error:

The procedure entry point _Z17qt_message_output9QtMsgTypePKc could not be located in the dynamic link library QtCore4.dll

I have all the necessary dlls in my application folder and they are the same ones that came with the binaries I've downloade开发者_StackOverflowd from the Qt's website. This error is driving me crazy for I can't seem to find any reason for it. The application runs fine on Linux and MAC OS X.

Ok I found the problem. I was copying the wrosng dll (not sure why Qt ships with 2 different versions).

The right ones are in:C:\Qt\2010.05\qt\bin and NOT in C:\Qt\2010.05\bin

I hope this helps anyone who might stumble upon this issue.
