Problem changing version 5.14 -> 5.15

when I compile my program that include only #include <TPolyMarker.h> I get this errors:

/bin/root/include/TPolyMarker.h:40: error: field ‘fOption’ has incomplete type
/bin/root/include/TPolyMarker.h: In member function ‘virtual const Option_t* TPolyMarker::GetOption() const’:
/bin/root/include/TPolyMarker.h:58: error: ‘fOption’ was not declared in this scope

is a my problem? (g++ (GCC) 4.1.0 (SUSE Linux))

I have fixed the problem in the CVS version.
Meanwhile #include “TString.h” in your application.
