APM Planner 2.0.14 debug version with Break point stuck

I can build and run APM Planner debug version in QT 3.12 / VS2010, but when I setup one break point, it stuck at the beginning - line 47 of PrimaryFlightDisplayQML.qml, the code is m_declarativeView = new QDeclarativeView(url); I don’t know why this happens. The last line in Application output is DEBUG 2014-08-15T13:47:02.942 QUrl( “file:///D:/Autonomous/APMPlanner/debug/qml/PrimaryFlightDisplayQML.qml” ). Anything I can try?
Thanks.

This usually means a problem with the build. Do a ‘clean’ then ‘build’ or simply ‘rebuild’ the project.

If it’s from the command line do ‘make clean’

I did “clean All” and “Rebuild All”, still go the same result. Any other possibilities?
Thanks.

what does ‘qmake -v’ return at the command line

qmake version 2.01a
Using Qt version 4.8.6

Try disabling QML debugging, under the Projects tab, select your current run configuration, and uncheck the “Enable QML” checkbox.

It works. I checked the debugger log, the only difference is “-qmljsdebugger=port:49956,block” is not there anymore.
Thanks.
