Добавление Xamarin.Google.iOS.SignIn приводит к ошибке встроенного связывания (MT5209)

Question

Я хотел заменить библиотеку Google.Plus из существующего приложения библиотекой Xamarin.Google.iOS.SignIn, используя Google Sign-In для iOS (https://components.xamarin.com/view/googleiossignin).

Однако ... при добавлении его и заменить старый код с новым (немного другой код), что приводит к ошибке компиляции:

/projectdir/MTOUCH: Error MT5209: Native linking error: file not found: /projectdir/obj/iPhoneSimulator/Debug/mtouch-cache/libOpenInChrome.a (MT5209) (Immo.Vlan.Touch) 
/projectdir/MTOUCH: Error MT5202: Native linking failed. Please review the build log. (MT5202) (Immo.Vlan.Touch)

Любые предложения о том, как справиться с этим?

Answer 1

После дополнительных исследований я думаю, что проблема в том, что нативные библиотеки упоминаться не включены в DLL. Если я открою DLL для текущей версии Google.Core (v1.3.2.1), то нет записи Resources. Если я открою v1.1.0beta-3, я могу увидеть запись ресурсов, содержащую все упомянутые библиотеки.

Таким образом, решение заключается в том, чтобы их правильно перестроить.

Я не уверен на 100%, что это ответ. По какой-то причине мой проект будет компилироваться отлично на симуляторе, но не на устройстве. Но тот факт, что он ссылается на недостающие имена, я думаю, очень наводящий на размышления.

Answer 2

Эти библиотеки dll больше не имеют встроенных библиотек. Добавление собственных библиотек теперь обрабатывается в дополнительной задаче сборки, которая добавляется в проект приложения, когда NuGet добавляется в проект приложения.

Обязательно добавьте NuGet или компонент в проект приложения.

Некоторые из них столкнулись с проблемой, когда Microsoft.Bcl.Build NuGet также добавлен в проект. В ближайшее время мы намерены выпустить патч для этой проблемы. Посмотрите версию 0.2.1 из Xamarin.Build.Download NuGet.

Чтобы обойти эту проблему вам нужно отредактировать файл цели packages/Xamarin.Build.Download.0.2.0/build/Xamarin.Build.Download.targets

Добавьте атрибут AfterTargets="AssignProjectConfiguration" к _XamarinBuildDownload цели.

<Target 
    Name="_XamarinBuildDownload" 
    DependsOnTargets="_XamarinBuildDownloadCore;_XamarinBuildAddDownloadedItems" 
    AfterTargets="AssignProjectConfiguration" 
    Condition="'@(XamarinBuildDownload)'!=''" 
    /> 

Answer 3

Я решил такую ​​же проблему с помощью Google Analytics на Xamarin IOS установки Xamarin.Build.Download 0.2.2-beta1

Я надеюсь, что это будет как можно скорее стабильной версии.
