Hi,

Thank you for the responses. As I said I am newbie in windows environment and my problem was that dll was not loaded. I put the dll in the same directory and later set the path environment variable to log4cxx installation directory and the problem is solved. On the other hand, the warnings are still displayed. I do not want to get rid of the warning by simply disabling them. Is there a proper way to disable them?

I provide warnings below.

Hello,

I am very much new to C++ programming in MS Windows environment. I am asked to develop a C++ application with QT 3.2.3 on Windows platform with MS Visual C++ 7.1 .Net edition. I have been developing C programs mostly on solaris and linux platforms.

After realizing that Qt 3.2.3 does not have a logging API other then some qDebug, qFatal, qWarning, I have seached for a logging library and found three different log4c++ implementation . After seaching for a while I understood that log4cxx is a part of Apache and decided to use log4cxx.

I have compiled the library as directed even though gathering eveything ant, jre, apr, cppunit took sometime.

Anyhow, I wanted to test the library, honestly for 2 days I have not been able to compile even simple examples. I receive zillions of errors that I provided in the end of the mail. I suspect that I may be missing to include some compilation flags. I used the qt qmake tool to generate a makefile as I am eventually use this tool with qt library.

In my test example I have only one file main.cpp which I have stolen form trivial.cpp (I have only changed the name of the trivial.cpp)
