[Log4cplus-devel] Using log4cplus with Qt 4.8.1

[Ulrich H. <uhe...@ib...>]

Hi,
i download yesterday the version log4cplus-1.1.0-rc5 and compile all
configurations with Visual Studio 2010 without errors. Then i create a
test console program with Qt 4.8.1. In the main.cpp I write the following:

#include <QtCore/QCoreApplication>
#include <log4cplus/logger.h>
#include <log4cplus/configurator.h>
#include <log4cplus/fileappender.h>
#include <log4cplus/layout.h>
#include <log4cplus/ndc.h>
#include <log4cplus/helpers/loglog.h>
#include <log4cplus/loggingmacros.h>

#include <iomanip>

using namespace std;
using namespace log4cplus;

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    PropertyConfigurator logger(L"log4cplus.conf",
log4cplus::Logger::getDefaultHierarchy());
    logger.configure();
    Logger::getRoot().log(INFO_LOG_LEVEL, L"Projektcenter");

    helpers::LogLog::getLogLog()->setInternalDebugging(true);
    SharedAppenderPtr append_1(new
RollingFileAppender(LOG4CPLUS_TEXT("Test.log"), 5*1024, 5));
    append_1->setName(LOG4CPLUS_TEXT("First"));
    append_1->setLayout( std::auto_ptr<Layout>(new TTCCLayout()) );
    Logger::getRoot().addAppender(append_1);

    Logger root = Logger::getRoot();
    Logger test = Logger::getInstance(LOG4CPLUS_TEXT("test"));
    Logger subTest = Logger::getInstance(LOG4CPLUS_TEXT("test.subtest"));

    return a.exec();
}

I set it include path to log4cplus-1.1.0-rc5/include and add the library
log4cplus-1.1.0-rc5/msvc10/win32/bin.Debug_Unicode/log4cplusUD.lib.
But i get 4 linker errors from Visual Studio:

1>main.obj : error LNK2019: Verweis auf nicht aufgelöstes externes

What's wrong?

Thanks
