Stephen - you're right... if the class itself is used, the compiler won't
know how to construct it... if it is a ptr, it won't complain.

RE: Forward Declaration
Somebody correct me if I'm wrong, but I don't think it will. In Test.hpp,
the compiler doesn't know what type LoggerPtr is. Since you're referring
to that type directly rather than by a pointer, the compiler needs to know
the full details. It doesn't know that in reality it's a pointer type
defined elsewhere. If for example, your code instead read:
...
class Test {
private:
static log4cxx::LoggerPtr* _logger;
...
then the compiler wouldn't complain.

Subject: Forward Declaration
Hello,
I'm wondering if it is possible to use forward declaration with log4cxx
classes in a class header file. I would like to exclude the log4cxx
headers files in my header files if possible and include the log4cxx
header files in my cpp(source) files.
Should this work?
// Test.hpp
namespace log4cxx {
class LoggerPtr;
}
class Test {
private:
static log4cxx:LoggerPtr _logger;
public:
Test();
};
//Test.cpp
#include <log4cxx/logger.h>
using namespace log4cxx;
LoggerPtr Test::_logger(Logger::getRootLogger());
Test::Test() {
}
// end test.cpp
Thanks,
-jd-
