Qml works fine on dev machine, crashes on others.
Using vs2010 qt5.2.1
i copied my release dir to a flashdrive and tried running it on another windows machine, but on execution it fails every time. I have the qml access through qrc, along with every resource access done through qrc in the qml code.
relevant CPP code:
@ m_view = new QQuickView;
m_container = QWidget::createWindowContainer(m_view);
m_uiRoot = m_view->rootObject(); //root object here gets set to NULL
Q_CHECK_PTR(m_uiRoot); // fails

Did you copied the binaries with your flashdrive, or your source files? Because when you copy your binaries, you need to copy all relevant dll files with it (asuming your "another windows machine" does not have qt installed on it).
To automate this you can use windeployqt. More information here: http://qt-project.org/doc/qt-5/windows-deployment.html#the-windows-deployment-tool
If this doesn't solve your problem, could you post the error message?
I got "Unable to locate ICU library icuin51.dll" which is really weird because the dll is in both my target binary's directory and windeployqt's directory.
NO LONGER ISSUE: fixed by adding my qt dir to %PATH%.
After running windeployqt, and trying copying the directory after that, still the same error.

You may be missing some plugins and qml directory.
@1. Please go to your installation take plugins like platform etc.
2. Go to qml directory and get some directories like QtQml, QtQuick.2 etc. @
These need to be there in the directory where you are placing your executable. This should fix your issue.
