使用Firebase Unity SDK的Firebase Xcode链接器命令错误 [英] Firebase Xcode linker command error using Firebase Unity SDK

问题描述

Firebase Unity SDK 1.1.1。
Unity 5.5.0p4
XCode 8.2.1使用来自Firebase的身份验证和数据库时在XCode中构建项目时出现以下错误：

我错过了XCode的东西吗？或者有什么需要检查的Unity？

谢谢！

解决方案

首先，感谢所有分享你的（努力）工作！

关于这个问题已经有很多人说过了，但是我花了一大笔钱。的时间和一大堆的反复试验来收集所有这些SO& Unity论坛，所以我只会发布最终解决方案，最终解决了所有的问题，使用统一云构建/ Unity 5.6.0f3 / Xcode 8.0，该项目只使用Firebase分析包

UNITY CLOUD BUILD

解决方案

• 完全禁用Unity的cocoapods>资产> Play服务解析器> iOS解析器>设置（取消选中Podfile生成和在编辑器中自动安装Cocoapod工具，选择无 - 不集成Cocoapods）
  p


• 将GoogleServices-Info.plist放入UnityAssets文件夹
  
• PostBuildProcessor方法：
  
  
  
  
  

   私有静态无效ProcessPostBuild（BuildTarget buildTarget，字符串路径）
   {
   //只对iOS执行这些步骤
   #if UNITY_IOS 
   
   Debug.Log（[UNITY_IOS] ProcessPostBuild  - 添加Google Analytics框架）; 
   
   //获取pbxproj文件
   string projPath = path +/Unity-iPhone.xcodeproj/project.pbxproj; 
   
   // PBXProject类表示一个项目的构建设置文件，
   //这里是如何读取。
   PBXProject proj = new PBXProject（）; 
   proj.ReadFromFile（projPath）; 
   //这是生成项目中的Xcode目标
   string target = proj.TargetGuidByName（Unity-iPhone）; 
   
   proj.AddBuildProperty（target，OTHER_LDFLAGS，-ObjC）; 
   proj.AddBuildProperty（target，OTHER_LDFLAGS，-v）; 
   proj.SetBuildProperty（target，ENABLE_BITCODE，NO）; 
   
   if（！File.Exists（path +/GoogleService-Info.plist））
   {
   FileUtil.CopyFileOrDirectory（Assets / GoogleService-Info.plist，路径+/GoogleService-Info.plist）; 
   
   string guid = proj.AddFile（GoogleService-Info.plist，GoogleService-Info.plist）; 
   proj.AddFileToBuild（target，guid）; 
   
   //将被添加到项目的框架列表
   List< string> frameworks = new List< string>（）{
  AddressBook.framework，
  AdSupport.framework，
  CoreData.framework，$ b $SystemConfiguration.framework， 
  }; 
   $ b $ //按名称添加
   frameworks.ForEach（（framework）=> {
   proj.AddFrameworkToProject（target，framework，false）; 
  }） ; 
   
   //将被添加到项目的框架列表
   List< string> usrLibFrameworks = new List< string>（）{
  libsqlite3.tbd，
  libz.tbd，
  libicucore.tbd，
  }; 
   $ b $ //按名称添加
   usrLibFrameworks.ForEach（（framework）=> {
   proj.AddFileToBuild（target，proj.AddFile（usr / lib /+框架，Frameworks /+框架，PBXSourceTree.Sdk））; 
  }）; 
   
   
   //将PBXProject对象写回文件
   proj.WriteToFile（projPath）; 
   
   #endif 
  } 
    

  sdk需要这样的黑客工作（UCB是我们的绝对要求，我猜大多数多平台的移动开发者），我希望所有这些解决方法很快就没用了，但是从官方firebase Unity的开始支持，我不会在这上面算太多的。
  

  Firebase Unity SDK 1.1.1. Unity 5.5.0p4 XCode 8.2.1

  When using Authentication and Database from Firebase I get the following error when building the project in XCode :

  Undefined symbols for architecture arm64:

  Do I miss something in XCode? Or have something to check in Unity?

  Thanks!

  解决方案

  First, thanks to all for sharing your (hard) work !

  A lot has been said on the subject, but it took me a lot of time and a lot of trial and error to gather all the pieces on both SO & Unity forums, so I will just post the solution that I finally worked out, which finally solved all issues for me, using unity cloud build/Unity 5.6.0f3/Xcode 8.0, the project using only firebase analytics package

  SOLUTION FOR UNITY CLOUD BUILD

  • completely disable cocoapods from Unity > Assets > Play Services Resolver > iOS Resolver > Settings (uncheck "Podfile Generation" and "Auto Install Cocoapod Tools in Editor", choose "None - do not integrate Cocoapods") p
  • put GoogleServices-Info.plist in the Unity "Assets" folder
  • PostBuildProcessor method:

  ---

  private static void ProcessPostBuild (BuildTarget buildTarget, string path)
  {
      // Only perform these steps for iOS builds
      #if UNITY_IOS
  
      Debug.Log ("[UNITY_IOS] ProcessPostBuild - Adding Google Analytics frameworks.");
  
      // Go get pbxproj file
      string projPath = path + "/Unity-iPhone.xcodeproj/project.pbxproj";
  
      // PBXProject class represents a project build settings file,
      // here is how to read that in.
      PBXProject proj = new PBXProject ();
      proj.ReadFromFile (projPath);
      // This is the Xcode target in the generated project
      string target = proj.TargetGuidByName("Unity-iPhone");
  
      proj.AddBuildProperty(target, "OTHER_LDFLAGS", "-ObjC");
      proj.AddBuildProperty(target, "OTHER_LDFLAGS", "-v");
      proj.SetBuildProperty(target, "ENABLE_BITCODE", "NO");
  
      if (!File.Exists(path + "/GoogleService-Info.plist"))
      {
          FileUtil.CopyFileOrDirectory("Assets/GoogleService-Info.plist", path + "/GoogleService-Info.plist");
      }
      string guid = proj.AddFile("GoogleService-Info.plist", "GoogleService-Info.plist");
      proj.AddFileToBuild(target, guid);
  
      // List of frameworks that will be added to project
      List<string> frameworks = new List<string>() {
          "AddressBook.framework",
          "AdSupport.framework",
          "CoreData.framework",
          "SystemConfiguration.framework",
      };
  
      // Add each by name
      frameworks.ForEach((framework) => {
          proj.AddFrameworkToProject(target, framework, false);
      });
  
      // List of frameworks that will be added to project
      List<string> usrLibFrameworks = new List<string>() {
          "libsqlite3.tbd",
          "libz.tbd",
          "libicucore.tbd",
      };
  
      // Add each by name
      usrLibFrameworks.ForEach((framework) => {
          proj.AddFileToBuild(target, proj.AddFile("usr/lib/"+ framework, "Frameworks/" + framework, PBXSourceTree.Sdk));
      });
  
  
      // Write PBXProject object back to the file
      proj.WriteToFile (projPath);
  
      #endif
  }
  

  PS it's crazy that firebase unity sdk is requiring such hacks to work (UCB is an absolute requirement for us and I guess for most multiplatform mobile developers) and I hope all those workarounds will soon be useless, but judging that all those issues are here from the beginning of official firebase Unity support, I wouldn't count too much on it
