ios 架构 x86_64 的 Firebase 未定义符号

Firebase Undefined symbols for architecture x86_64

提问by gdev

I am using firebase as part of a project I am working on in iOS, and I just stumbled upon the following linking error when I try to compile my code against an iPhone 6 or 7 simulator for testing.

我正在使用 firebase 作为我在 iOS 中工作的项目的一部分，当我尝试针对 iPhone 6 或 7 模拟器编译代码进行测试时，我偶然发现了以下链接错误。

Undefined symbols for architecture x86_64:

I am using Xcode 8.2.1, swift 3.0, and I also have the following Pod file in my project

我正在使用 Xcode 8.2.1、swift 3.0，并且我的项目中还有以下 Pod 文件

pod 'Braintree'
pod 'Firebase/Auth'
pod 'Firebase/Database'
pod 'Firebase/Core'
pod 'Firebase/Storage'
pod 'Firebase/Messaging'
pod 'Firebase/RemoteConfig'
pod 'GeoFire', :git=>'https://github.com/firebase/geofire-objc.git'
pod 'ObjectMapper', '~> 2.2'

I have done a pod update in case something was out of date, but no luck. The code compiles and runs fine when I use an iPhone 4 or 5 simulator.

我已经做了一个 pod 更新，以防万一过时，但没有运气。当我使用 iPhone 4 或 5 模拟器时，代码编译并运行良好。

Edit:

编辑：

I have set Build Active architectures to No, in valid architectures I have listed arm64, armv7, armv7s and now Objectmapper is failing even though import ObjectMapperis declared in the file

我已将 Build Active architectures 设置为 No，在有效的体系结构中我列出了 arm64、armv7、armv7s，现在即使import ObjectMapper在文件中声明了Objectmapper 也失败了

 Use of undeclared type 'Mappable'

Any help would be greatly appreciated! Thank you in advance.

任何帮助将不胜感激！先感谢您。

It seems to be a glitch with derived data. I quitted out of Xcode, I removed all Derived Data in /Users/USER_NAME/Library/Developer/Xcode/PROJECT_NAME

派生数据似乎有问题。我退出了 Xcode，我删除了所有派生数据/Users/USER_NAME/Library/Developer/Xcode/PROJECT_NAME

Restarted Xcode, compiled and all works as expected, no need to change anything in Active Architecture Onlyor anything.

重新启动 Xcode，编译并按预期工作，无需更改任何内容Active Architecture Only或任何内容。

For me I just installed Firebase framework to Xcode, not using CocoaPods due to other unsolvable issues. After build there is similar errors like above with "symbol(s) not found for architecture x86_64". (maybe because I am working with Xcode on VMWare)

对我来说，我只是将 Firebase 框架安装到 Xcode，由于其他无法解决的问题，我没有使用 CocoaPods。构建后有类似上面的错误，“没有找到架构 x86_64 的符号”。（也许是因为我在 VMWare 上使用 Xcode）

Then I have to manually go to General - Linked Frameworks and Librariesand add:

然后我必须手动转到General - Linked Frameworks and Libraries并添加：

libsqlite3.tbd, libz.tbd, libc++.tbd

libsqlite3.tbd、libz.tbd、libc++.tbd

for the project to work.

使项目正常工作。

Just discovered a similar problem and got it solved by clearing Pod-Cache.

刚刚发现了一个类似的问题，并通过清除 Pod-Cache 解决了它。

Clear CocoaPods Cache

清除 CocoaPods 缓存

pod deintegrate && pod cache clean --all

pod deintegrate && pod cache clean --all

Re-Install Pods

重新安装 Pod

pod install

I tried the "clearing Cocoapods cache" and the "removing derived data" solutions but that didn't work. What worked for me was a step I found in the Carthage setup (I'm still using Cocoapods)

我尝试了“清除 Cocoapods 缓存”和“删除派生数据”解决方案，但没有奏效。对我有用的是我在 Carthage 设置中找到的一个步骤（我仍在使用 Cocoapods）

Add $(OTHER_LDFLAGS) -ObjCflag to "Other Linker Flags" in "Build Settings".

将$(OTHER_LDFLAGS) -ObjC标志添加到“构建设置”中的“其他链接器标志”。

You can see the step here: https://github.com/firebase/firebase-ios-sdk/blob/master/Carthage.md

Also had this problem after installing pods for Firebase, using CocoaPods as explained in the Firebase site:

使用 CocoaPods 为 Firebase 安装 pod 后也遇到了这个问题，如 Firebase 站点中所述：

https://firebase.google.com/docs/ios/setup?hl=es-419#prerequisites

https://firebase.google.com/docs/ios/setup?hl=es-419#prerequisites

pod 'Firebase/Analytics' pod 'Firebase/Auth'

吊舱“Firebase/Analytics”吊舱“Firebase/Auth”

During the installation of the pods I received a warning telling that:

在安装 Pod 的过程中，我收到了一条警告：

[!] The target `myTarget [Debug]` overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Pods.xcconfig'.
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

[!] The target `myTarget [Release]` overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Pods.xcconfig'.
    - Use the `$(inherited)` flag, or
    - Remove the build settings from the target.

When I compiled I got the error for several files:

当我编译时，我收到了几个文件的错误：

Undefined symbols for architecture x86_64:

I tried the solution of the following answer before the one in this answer, and it worked as a charm:

我在本答案中的答案之前尝试了以下答案的解决方案，它很有魅力：

The target ... overrides the `OTHER_LDFLAGS` build setting defined in `Pods/Pods.xcconfig

目标 ... 覆盖 `Pods/Pods.xcconfig 中定义的 `OTHER_LDFLAGS` 构建设置

Basically the solution was (as explained by @Ankish Jain):

基本上解决方案是（如@Ankish Jain 所解释的）：

Go to your TargetBuild Settings -> Other linker flags -> double click -> + button. Add $(inherited) to a new line.

转到您的目标构建设置 -> 其他链接器标志 -> 双击 -> + 按钮。将 $(inherited) 添加到新行。

After that I compiled succesfully, and new flag where added automatically to the Build Settings.

之后我编译成功，新标志自动添加到构建设置中。

I tried the solutions in this question, and nothing worked. Also found other threads in SO and GitHub issues. Nothing helped. I am using Xcode 9.2, Swift 4, latest version of cocoa pods. This worked for me...

我尝试了这个问题中的解决方案，但没有任何效果。还在 SO 和 GitHub 问题中找到了其他线程。没有任何帮助。我正在使用 Xcode 9.2、Swift 4、最新版本的可可豆荚。这对我有用...

First, my podfile only contains one firebase pod since I am only using Analytics at this point, however solution approach should be the same if you're using more.
pod 'Firebase/Core'

首先，我的 podfile 只包含一个 firebase pod，因为此时我只使用 Analytics，但是如果您使用更多，解决方法应该是相同的。
吊舱“Firebase/核心”

Second, like documentation states, make sure -ObjC is added to your Other Linker Flags. I did this both at project and target level build settings. They were different.

其次，像文档说明一样，确保将 -ObjC 添加到您的其他链接器标志中。我在项目和目标级别的构建设置中都这样做了。他们是不同的。

Third and most important, at Project level build settings, Other Linker Flags, add the following

第三个也是最重要的，在项目级别的构建设置，其他链接器标志，添加以下内容

-framework

-框架

"FirebaseCore"

“火力地基核心”

-framework

"FirebaseAnalytics"

“Firebase 分析”

-framework

"FirebaseInstanceID"

"FirebaseNanoPB"

Had the same problem, and for me the issue was that I had imported the FirebaseMessaging framework manually, by downloading the entire Firebase SDK and then manually importing the Messaging framework into the project (I didn't use Cocoapods or Carthage). I didn't import the other framework in the same folder, "Protobuf.framework". Once adding Protobuf and making sure the target memberships included my project target, it worked.

遇到了同样的问题，对我来说，问题是我手动导入了 FirebaseMessaging 框架，方法是下载整个 Firebase SDK，然后手动将 Messaging 框架导入到项目中（我没有使用 Cocoapods 或 Carthage）。我没有在同一个文件夹“Protobuf.framework”中导入另一个框架。添加 Protobuf 并确保目标成员资格包括我的项目目标后，它就起作用了。

Also had this issue...
Added $(inherited)to other linker flags in build settings and everything works fine now

也有这个问题......
添加 $(inherited)到构建设置中的其他链接器标志，现在一切正常

回答by Ryan

I encountered this issue before, It looks like you need to:

我之前遇到过这个问题，看来您需要：

rm -rf ios/Podfile ios/Podfile.lock ios/Pods ios/Runner.xcworkspace

rm -rf ios/Podfile ios/Podfile.lock ios/Pods ios/Runner.xcworkspace

and then run flutter run

然后运行 flutter run

UPDATE: run this fix the issue too: rm -f ios/Runner.xcworkspace/xcshareddata/WorkspaceSettings.xcsettings

更新：也运行此修复问题： rm -f ios/Runner.xcworkspace/xcshareddata/WorkspaceSettings.xcsettings

In my case, for using only Firebase Auth and Firebase Firestore, installing with Cocoapods, all I had to do was click the +sign for both Debugand Releasesections under Other Linker Flagsin Build Settings. The $(inherited)flag was added automatically. Built just fine after that!

就我而言，为了仅使用 Firebase Auth 和 Firebase Firestore，使用 Cocoapods 进行安装，我所要做的就是单击Build Settings下的和部分的+标志。该标志是自动添加的。在那之后建造得很好！DebugReleaseOther Linker Flags$(inherited)
