No. LoggerPtr is a template expansion and you'd need at least the
template definition incorporate it in a header file. However, you may
want to consider not having a LoggerPtr in your class definition at
all, but just have it in your implementation. Something like:
myfoo.cpp
#include <log4cxx/logger.h>
// anonymous namespace, members are visible only in this compilation
unit
// like static but better
//
namespace {
log4cxx::LoggerPtr logger(log4cxx::Logger::getRootLogger());
}
void Foo::someFunction() {
LOG4CXX_INFO(logger, "Hello, World");
}
