Multiple dylib versions created

  • Why multiple versions of dylibs are created in Mac and I had to include 2 different versions of dylib to make it work in another application.Where if i include one , it asks for another version?

    Hi and welcome to devnet,

    What library are you talking about ?
    What versions ?
    What are you trying to do ?
    What version of macOS ?
    What version of Qt ?
    What version of Xcode ?

  • @SGaist Hi, I wanted to create a dynamic library in mac using Qt Libraries project option.
    So, When write a sample code and build it. It Creates more than one version like: -
    My Question is why it created these 4 different versions of same library and when I integrate libSample.1.0.0.dylib this in an other application, It builds but asks for libSample.1.dylib for complete execution of my application which integrates this sample library i created.

    I am using Qt creator 4.10.2 based on Qt 5.13.2 (Clang 10.0 (Apple), 64 bit) and using Xcode 9.
    i am using macos 10.14.3

    Thanks in advance.

    That's how library numbering is working in Unix style OSs. Same goes for Linux with their .so files.

    This allows you to link to a more or less precise version of a library. The numbers are major/minor/patch. You usually link to the unnumbered version but if you need some specific version because of some specific behavior that has changed, you can link using the version number.
