c++ - undefined reference to function from log4cpp library -


i have problem ... downloaded log4cpp library , compiled via microsoft visual studio .lib-file. want link library qt project, whenever call function, such as

std::string initfilename = "log.properties"; log4cpp::propertyconfigurator::configure(initfilename);

i lots of errors saying 

"undefined reference `log4cpp::propertyconfigurator::configure(std::string const&)'"

here's code in project file:

win32:config(release, debug|release): libs += -l$$pwd/log4cpp/ -llog4cpplib else:win32:config(debug, debug|release): libs += -l$$pwd/log4cpp/ -llog4cppd else:unix: libs += -l$$pwd/log4cpp/ -llog4cpplib  includepath += $$pwd/log4cpp/include dependpath += $$pwd/log4cpp/include

i don't know, :(

if library compiled visual studio, should configure project use same compiler instead of mingw/gcc.
