架构armv7的未定义符号：“_OBJC_CLASS _ $ _ GGLContext”，引用自：AppDelegate.o中的objc-class-ref [英] Undefined symbols for architecture armv7: "_OBJC_CLASS_$_GGLContext", referenced from: objc-class-ref in AppDelegate.o

问题描述

我正尝试在我的iSO应用中添加Google Analytics，并使用Google Analytics最新SDK
https://developers.google.com/analytics/devguides/collection/ios/v3/ 。

已添加所有必需的标题和框架成功地完成了我的项目。但是，在运行我的应用程序时，我得到了以下错误：
$ b $ ol

（null）：_OBJC_CLASS _ $ _ GGLContext，引用来自：objc- AppDelegate.o中的class-ref

（null）：链接器命令失败，退出代码1（使用-v查看调用）

以下是我在AppDelegate.m文件中写的代码

  //从GoogleService-Info.plist中配置跟踪器。 
 NSError * configureError; 
 [[GGLContext sharedInstance] configureWithError：& configureError]; 
 NSAssert（！configureError，@配置Google服务时出错：％@，configureError）; 
 
 //可选：配置GAI选项。 
 GAI * gai = [GAI sharedInstance]; 
 gai.trackUncaughtExceptions = YES; //报告未捕获的异常
 gai.logger.logLevel = kGAILogLevelVerbose; //删除应用发布之前
  

还包括（_OBJC_CLASS _ $ _ GIDSignInButton和_OBJC_CLASS _ $ _ GIDSignIn）
请告诉我缺少的东西。

OTHER_LDFLAGS 编译设置。这是主要问题。在其他链接器标志的新行中添加$（继承）后解决了我的问题。

I am trying to add Google Analytics in my iSO app and I am using Google Analytics latest SDK https://developers.google.com/analytics/devguides/collection/ios/v3/.

Added all required header and frameworks to my project successfully. But while running my app I am getting below errors

1. (null): "_OBJC_CLASS_$_GGLContext", referenced from:objc-class-ref in AppDelegate.o

2. (null): Linker command failed with exit code 1 (use -v to see invocation)

Below is the code which I am writtig in AppDelegate.m file

// Configure tracker from GoogleService-Info.plist.
NSError *configureError;
[[GGLContext sharedInstance] configureWithError:&configureError];
NSAssert(!configureError, @"Error configuring Google services: %@", configureError);

// Optional: configure GAI options.
GAI *gai = [GAI sharedInstance];
gai.trackUncaughtExceptions = YES;  // report uncaught exceptions
gai.logger.logLevel = kGAILogLevelVerbose;  // remove before app release

Also includes (_OBJC_CLASS_$_GIDSignInButton and _OBJC_CLASS_$_GIDSignIn) Please tell what I am missing. Thanks in advance.

解决方案

"The OPN [Debug] target overrides the OTHER_LDFLAGS build setting". This was the main issue. After adding $(inherited) in new line in other linker flags solved my issue.
