With Nokia Qt sdk application doesn't deploy on device

[giorgiogio48]

Hello friends,
I am working with Nokia Qt Sdk. I created a simple application in c++ language. It compiles with Qt simulator, but doesn't deploy on device because the open c++ plugin.
The error message says that open c++ plugin. isn't found or is misconfigured.
Then I installed the open c++ plugin, but the same error.
Any help?
Thanks.

Which phone model? Note that only Symbian^3 devices come with Qt (v4.6.3) preinstalled. On all others you must install the Qt runtime before or with your application (in its entirety, or selectively as required by using the Nokia Smart Installer).

Install the qt_installer.sisx from your SDK directory on the N97, before trying to install your Qt apps on it.
