Compiling

An error similar to the following occurs when you start compiling:

Src\main\include\log4cxx\spi\loggingevent.h: Error C2252: Template ' error can only be explicitly instantiated within namespace scope.

Workaround: A to double-click the error row in the Output window, where the error occurs in the Code window. b Select Log4cxx_list_def, press keyboard F12, and then jump to definition C of the macro to

#define LOG4CXX_LIST_DEF (N, T) \  
template class Log4cxx_export std::allocator<t>; \  
template class Log4cxx_export std::vector<t>; \  
typedef std::vector<t> N  

To be replaced by:

#define LOG4CXX_LIST_DEF (n, T) \  
typedef std::vector<t> N

If you report the following error:
C2039 "Insert_iterator": not a member of "Std"

Solution:
Add to source file header: #include

Note: Log4cxx is not recommended (too cumbersome to compile) and recommended for use with Spdlog
