Any equivalent debug output TRACE in codeblocks and MinGW

[ollydbg]

Hi, If I design a GUI project in C::B and Mingw, For example, a wxWidgets project. How can I output the debug information.

I have the experience in MFC in windows, there TRACE() / OutputDebugString() can output the debug information in the output window of visual studio IDE.

So, What's the equivalent way in C::B? Once I know that printf can be redirect to GDB's output window, is it the only way?

Thanks.
