Weird corrupted String



  • I am having a string issue with the following code:
    foreach (const QCameraInfo &deviceName, QCameraInfo::availableCameras())

    If I compile the program on my machine and transfer the exe and DLLs to the target machine, the deviceName() method returns a '.' (this may actually be something besides a period in Hex, but I won't know that until I can get the target system back.)

    If I copy the code to the target machine and build it there, then the issue goes away. I was thinking it may have something to do with the fact my development machine is 64 bit, but the target system is 32. Even though I was building for 32 bit, I thought maybe something was not getting translated correctly. However, when I took the exe from one target system and placed it on another identical system the problem came back.

    Anyone have any idea what is going on?

    Thanks in advance,
    Bear

    Hi,

    Windows ? Did you deploy all DLLs with your application ? Including the QtMultimedia plugins ?



  • @SGaist Yes it is Windows 7. The target is Windows 7 Embedded. Yes I did deploy the DLLS but as soon as the system comes back from the testing I will verify that.



  • @SGaist Thanks again. I was missing plugins. After copying them over to the target system along with a freshly compiled exe from my development system, my exe ran just fine.

    Those plugins can be tricky…

    Happy coding !
