How do you resolve 'ostream' ambiguous symbol error?

[Jeff Lynn <jm...@yahoo.com>]

Hi,
 
Can someone help me by pointing out what need to be done to resolve the following error when I declared log4cxx name space inside the header file of a C++ class?
 
   D:\VisualStudio\VC98\INCLUDE\ios.h(159) : error C2872: 'ostream' : ambiguous symbol
 
I can declare and use LoggerPtr as global variable in the C++ file, yet when declared inside a C++ header file, got the above error.
 
I would like to declare the LoggerPtr instance as a member variable of each class instead of as a global variable.
 
Thanks!
 
jml

You may need to remove any "namespace log4cxx" and use 
"log4cxx::LoggerPtr" to declare your logger reference.  By removing the 
"namespace log4cxx", you will eliminate the ambiguity between 
log4cxx::ostream and std::ostream.
