Hi StanleyH, I use Qt as well and get these errors during compilation but they can of course be ignored. If you want you can add
QMAKE_CXXFLAGS += /wd4100 to your projects .pro file to silence the output or modify the source file(s) to remove the reference. -- Bill. -- View this message in context: http://activemq.2283324.n4.nabble.com/Error-while-try-compile-hello-world-for-ActiveMQ-CPP-in-QT-Creator-tp4271554p4272492.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
