I think you'd so something like:
template <class T> class Example {
Example() {}
void doSomething() {
LOG4CXX_DEBUG(getLogger(), "Hello, World");
}private:
log4cxx::LoggerRef& getLogger() {
static log4cxx::LoggerRef logger(log4cxx::Logger::getLogger(
LOG4CXX_LOCATION.getClassName()));
return logger;
}
};The code fragment depends on the LocationInfo class introduced after 0.9.7 to get the class name. The class name may be returned as "" for early Microsoft compilers ( _MSC_VER < 1300). Please feel free to enhance include/log4cxx/spi/location/locationinfo.h if your compiler can return class location but the macros don't handle it.

Does no one else have a problem with needing to log messages from templated classes? If anyone else has solved this problem, I would very much like to hear your solution.
Thanks, Daniel

Specifically, the problem I don't have a good solution for is the static instantiation of a logger object at all, let alone one that has a name giving the particular class for which the template is being used.
