WINCE app can not run

[baby911]

I built an app on WINCE 5 with Qt-Embed 4.5.2 and VS2008, but there's an error " app is not a valid Pocket PC application. " when I run this program on my CE device and CE emulator.

So is there anyone can give me some idea about this problem.

Thanks

the information you provided is not enough to say anything....
which qt-wince package you downloaded? did you compiled it yourself or got an binary package?

first of all try to make a simple Non-Qt application from the new project wizard of vs2008 and see if you can run it on emulator.

I download the source code of Qt embedded wince opensource 4.5.2, and I just compiled it successsfully. And I just built this app under VS2008 and deploy it on my CE device. But I can not run it up.

I built an MFC WINCE app just few minutes ago, and it can run successfully both on my device and emulator.

try to build the example programs that comes with qt

[baby911]

I had tried Qt examples, it's the same problem.

are you supplying all the required dlls to the device? you can see the required dlls by dependency walker.

[baby911]

All dll files, including QtCore4.dll QtGui4.dll msvcr90.dll, and my app had deployed.

well then there is nothing left we can do now.. the only possibility is that the exe is not compiled as wince app... try to run the exe directly in windows with qt windows dlls and see what the error says...

[baby911]

I just ran this app, but windows told me that's not a valid win32 application

try to set up qt on another machine ... dont know how to solve this error
