log4cxx is an excellent library for logging with a huge amount
features:
http://logging.apache.org/log4cxx/manual/Introduction.html
My friend persuaded me to install it. However, I have a problem
compiling a simple program. This is the program:
#include <iostream>
#include "server.h"
#include <log4cxx/logger.h>
#include <log4cxx/ndc.h>
#include <log4cxx/basicconfigurator.h>
#include <log4cxx/propertyconfigurator.h>
#include <log4cxx/helpers/exception.h>
using namespace std;
using namespace ost;
using namespace log4cxx;
using namespace log4cxx::helpers;
int main()
{
int result = EXIT_SUCCESS;
try
{
BasicConfigurator::configure();
LoggerPtr rootLogger = Logger::getRootLogger();
NDC::push(_T("trivial context"));
rootLogger->debug(_T("debug message"));
rootLogger->info(_T("info message"));
rootLogger->warn(_T("warn message"));
rootLogger->error(_T("error message"));
rootLogger->fatal(_T("fatal message"));
}
catch(Exception&)
{
result = EXIT_FAILURE;
}
return result;
}
I receive these error messages:
In function `main':
: undefined reference to `log4cxx::BasicConfigurator::configure()'
/home/maksim/tmp/ccvVAxjg.o(.text+0x44): In function `main':
: undefined reference to `log4cxx::Logger::getRootLogger()'
I included all the header files needed. I think the problem is in how I
compile the program. Maybe I need to include a library? The problem is
that I did not find any libraries in the log4cxx folder.
g++ -D_REENTRANT -pipe -O3 -march=i586 -fomit-frame-pointer
-I/home/maksim/projects/log4cxx-0.9.7/include -D_GNU_SOURCE
-L/usr/local/lib -lccgnu2 -ldl -lrt -pthread *.cpp -o server
Any help is appreciated (my program also uses GNU common C++ library).
