Zbar SDK is not working in iOS6

I was using ZBar for scanning in iOS5 and it was working well.

Now after updating to iOS6, its not working. It shows a following error.

    ld: file is universal (3 slices) but does not contain a(n) armv7s slice: /Users/mac4/Desktop/my desktop/My app/MyApp name 20:09:12  /MyApp name/ZBarSDK/libzbar.a for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)

What is wrong in my side?

Solution

  • i recently faced the same issue. The problem seems to be that the ZBar SDK is not ready for the armv7s architecture.

    I solved the problem this way:

    1. Go to the ZBar homepage and navigate to the mercurial repository (direct link)
    2. Download the zbar repository as zip.
    3. Unzip the file and navigate to the subfolder named "iphone".
    4. Open the XCode project.
    5. Delete the "Examples" folder (the folder caused a build error on my machine).
    6. Hit "CMD + B" and build the source.
    7. Find your new libzbar.a file. (User/Library/Developer/Xcode/DerivedData/zbar...)
    8. Replace the old libzbar.a file in your project with the new one.
    9. Hit "CMD + R" and you are good to go.
