[Reg 6.7 -> 6.8.0][iOS] CMake projects can no longer manually link to libqiosnsphotolibrarysupport.a

    XMLWordPrintable

Details

    • iOS/tvOS/watchOS

    Description

      A CMake project which uses the native iOS photo picker must manually link to libqiosnsphotolibrarysupport.a, unlike qmake (see comments at QTBUG-120676)

       

      Unfortunately, this causes linking errors in Qt 6.8.0:

      Undefined symbols for architecture x86_64:
  "_ALAssetPropertyAssetURL", referenced from:
      ____ZN13QIOSAssetDataC2ERK7QStringP27QIOSFileEngineAssetsLibrary_block_invoke_2 in libqiosnsphotolibrarysupport.a(qiosfileengineassetslibrary.mm.o)

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

       

      See the attached archive, which contains both qmake and CMake versions of the same project.
