Could you not go with standard iostreams for log4cxx then? I mean, given that iostreams tend to be entirely in headers, it seems like you could compile log4cxx with an iostreams library independant of what your customers have.At least for the Microsoft platform, you are not allowed to mix old and standard iostream include files within a single executable or DLL. See http://msdn.microsoft.com/library/default.asp?url=/library/en-us/ vccore98/html/_core_differences_in_iostream_implementation.asp.
I believe you can get around this limitation by using STLport iostreams when you build log4cxx.
