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)
