cegui_mk2-0.2.1 and Fedora Core 4 compilation

[apperenticegp]

Hello everybody. I'm having problems compiling the said release on my newly installed Fedora Core 4 on my Athlon64 PC. Here are the error messages:

../include/CEGUISingleton.h: In constructor 'CEGUI::Singleton<T>::Singleton() [with T = CEGUI::Logger]':
../include/CEGUILogger.h:146: instantiated from here

How can I fix this one?

You might consider the latest 0.3.0 release (although without a 'cvs update' done on it, that has it's own issue under FC4).

Anyhow, to fix this issue, try the following patch:

Thank you very much CrazyEddie. It worked! I'll also check the CVS version of version 3. You were right about having issues on the latest download on Fedora Core 4.
