Hi all, i'm using for the first time this logging library and i have a 
link problem :

i'm using VC++ 6.0.
this is the code i'm using:
#include "log4cxx/logger.h"
#include "log4cxx/propertyconfigurator.h"
using namespace log4cxx;
[...]
LoggerPtr mainLogger = Logger::getLogger("Main");
[...]
GetCurrentDirectory(1024,strDir);
strcat(strDir,"\\properties\\main_service_logger.properties");    
PropertyConfigurator::configure(strDir);

LOG4CXX_DEBUG(mainLogger, "Hi all");
i put log4cxx.lib, log4cxx.exp and log4cxx.dll  in my Lib directory
Also i set Link properties to add log4cxx.lib but still got this problem.
My application is a win32 service
Any ideas?
Thanks in advance!
Massimo
