Library Not Loaded on startup using Native Reference to HockeySDK RRS feed

  • Question

  • User232349 posted

    This is a repost of sorts of the last comment in this thread: https://forums.xamarin.com/discussion/67130/hockeysdk-for-xamarin-mac#latest

    I have separated this out for clarity as it is actually a different error to the main theme of that thread.

    We are getting an error at startup running any application that has a native reference to the HockeySDK (available at https://download.hockeyapp.net/sdk/mac/HockeySDK-Mac-4.1.0-beta.4.zip)

    The error experienced is

    Process:               HockeySDKApp [4219]
    Path:                  /Users/USER/*/HockeySDKApp.app/Contents/MacOS/HockeySDKApp

    I have attached a number files to help with the reproduction of this problem.

    First is "HockeySDKXamarin.zip". Running this should show the crash (with errors appearing in ~/Library/Logs/DiagnosticReports) Second is "HockeySDKXCode.zip". This shows HockeySDK.framework loading correctly from an equivalent XCode solution.

    Curiously, if within the XCode solution HockeySDK.framework isn't correctly copied to the Framework folder using a Copy FIles Build Phase, the same exact error as above (as with Xamarin occurs). This would suggest the app coming out of Xamarin cannot find HockeySDK.framework. Expanding the application package does however reveal it is there. Is there a permissions or signing issue?

    Any help appreciated! Andrew

    Alright, so unfortunately there are a few paths around mmp, and this use case missed the ones we tested.

    The problem is that we've added assemblies in HockeySDKApp.app/Contents/Frameworks but never informed the final executable of this.

    You can run this command post build to fix this:

    installnametool ./HockeySDKApp.app/Contents/MacOS/HockeySDKApp -addrpath @loaderpath/../Frameworks

    until we get this fixed on our end.

    Thanks @ChrisHamons.

    I can confirm this works.

    For those referencing in the future, I added a "After Build" Custom Command in the Project Options as follows:

    install_name_tool ${TargetDir}/HockeySDKApp.app/Contents/MacOS/HockeySDKApp -add_rpath @loader_path/../Frameworks.

    I think we may be the first people in the history of civilisation to attempt to get HockeyApp for Mac working in Xamarin, so I will upload to github a working solution once we have everything sorted and post the link as a comment here.

    @llevera Hi!

    We also working on mac app with Xamarin and would like to have HockeyApp integrated. Do you have any success with binding library?
