"Native linking failed" error occured when using Mobile Center in Xamarin.iOS project about appcenter-sdk-dotnet

[guperrot]

This issue is already being followed up on Intercom support center.

Add "-gcc_flags -dead_strip" to additional mtouch arguments in project's iOS Build options, now build succeed.

[softlion]

How did you find that ...

[tbaggett]

FYI, adding "-gcc_flags -dead_strip" as suggested above made no difference for me. I manually deleted the bin and obj folders, tried rebuilding the solution and still see the same errors.

[guperrot]

@tbaggett any chance you can share the sources? Or reproduce the bug in a sample app you can share?

[softlion]

Happens only when using mobile distribution nuget on iOS.

[guperrot]

We can't reproduce the issue in any of our test builds, so we would need to look at someone's sources that experience the issue.

[guperrot]

Still no volunteer for sharing sources?

[irreal]

This is extremely frustrating to me.
My main project fails with these exact same errors everytime I add distribute to iOS.
I am currently on 0.17.1, the version released about an hour ago, with all my packages.

I have spent the entire day today trying to do two things : fix my app's build and break the build of a new sample app that I've created to repro the issue.
I cannot do either so far :(

[guperrot]

@irreal I don't have an issue with a sample app, can you share your own sample app? Or are you saying the sample app does not have the issue?

[guperrot]

@irreal @tbaggett @softlion

We will need someone on this thread to provide us a reproduction scenario, none of our team members can reproduce the issue.

Sharing sources might be the only way for us to investigate that issue at this point.

[guperrot]

Closing this again as no-one shared enough details to reproduce the issue. Will re-open if someone provide sources or a reproduction scenario.

This happened to me just now as soon as I upgraded App Center. Was fine before. I will share whatever you need. I guess I'll just downgrade now, as its late in the game, we're supposed to pilot soon :(

[guperrot]

Make sure you have done a full clean build (close Visual Studio, remove every obj/bin folders manually, clean solution does not enough).

[attrib75]

Thanks I'll give it a shot

[attrib75]

This didn't work. thanks

[guperrot]

Thanks for sharing sample sources showing the problem and exact reproduction steps. As it was mentioned multiple times in the thread before, we never ever were able to reproduce the problem in any of our test apps so the only way for us to investigate this issue is to have someone willing to share sources so we can investigate.

[attrib75]

Yes, I can do that as I said. Where and how do I send it

[guperrot]

If sources are private, you can contact us on intercom which is the dedicated and official/main support center of AppCenter. This can be accessed via the blue chat button on any https://appcenter.ms page.

[guperrot]

Hey, we have not heard from you in a while and have not received sources so we will close the ticket now.
Given the nature of the issue we reopen only if someone share sources that can clearly show the issue is produced.

I get this error when there's still HockeyApp code present in the iOS-project, regardless of the order the code exists in the AppDelegate. I commented out all HockeyApp-source code and my projects build, all including the AppCenter nugets. I might use seperate build configurations for dev,tst,acc and prd, but for now I thought I'd offer a solution. :) I hope this works for everyone still struggling with this.

Just got this error again. Right before a customer demo!

I'll send you whatever you need asap.

[iamclement]

Hello, please provide us sample sources showing the problem and exact reproduction steps. Thanks

[Martyf101]

Just got this error. Happens whenever i comment out AppCenter.Start(...); Compiles fine again when i add it back in.
