xcode 是什么导致此 Crashlytics 编译警告？（自动链接在“...”处提供的“...”框架链接器选项不是 dylib）

What is causing this Crashlytics compile warning? (Auto-Linking supplied '...' framework linker option at '...' is not a dylib)

提问by Robert

Compiling my main target (not a test target like here) yields this error:

编译我的主要目标（不是像这里这样的测试目标）会产生这个错误：

ld: warning: Auto-Linking supplied 
   '~/Documents/my_app/MyApp/Crashlytics.framework/Crashlytics', 
framework linker option at 
    ~/Documents/my_app/MyApp/Crashlytics.framework/Crashlytics 
is not a dylib

The Missing Link:

缺失的链接：

This error is almost always produced by not having the binary linked to the library (In this case it would be the Crashlytics.framework):

这个错误几乎总是由于没有将二进制链接到库而产生的（在这种情况下，它将是Crashlytics.framework）：

Trying to build the target MyApp(which includes headers with #import <Crashlytics/Crashlytics.h>will produce the error:

尝试构建目标MyApp（包括标头）#import <Crashlytics/Crashlytics.h>将产生错误：

ld: warning: Auto-Linking supplied '../../Crashlytics.framework/Crashlytics', framework linker option at ../../Crashlytics.framework/Crashlytics is not a dylib

ld：警告：自动链接提供了“../../Crashlytics.framework/Crashlytics”，../../Crashlytics.framework/Crashlytics 中的框架链接器选项不是动态库

Link the Framework:

链接框架：

Fortunately, it should be easy to fix the problem simply by dragging the Crashlytics.frameworkfrom the Frameworksfolder in the project navigator into the list of Link Binary With Librariesor by using the +.

幸运的是，只需将项目导航器中Crashlytics.framework的Frameworks文件夹中的拖放到 的列表中Link Binary With Libraries或使用+.

• Make sure you have your App selected/highlighted under Targets while doing this process.

• 确保在执行此过程时在目标下选择/突出显示您的应用程序。

I had the same issue but my reason was different.

我有同样的问题，但我的原因不同。

Reason

原因

• My target was overriding the OTHER_LDFLAGS.

• 我的目标是覆盖OTHER_LDFLAGS.

Solution

解决方案

• Changed the OTHER_LDFLAGSto just inherit the Linker Flags. Basically, changed it to $(inherited)

• 将 更改OTHER_LDFLAGS为仅继承链接器标志。基本上，将其更改为$(inherited)

I followed all steps provided by @i'L'i but I was not able to find Crashlytics.frameworkand Fabric.frameworkfile in build phases.

我遵循了@i'L'i 提供的所有步骤，但无法在构建阶段找到Crashlytics.framework并Fabric.framework归档。

So this helped me.

所以这对我有帮助。

Step 1:Follow all the steps given Here.

第 1 步：按照此处给出的所有步骤进行操作。

Step 2:Now when you are unable to find Crashlytics.frameworkand Fabric.frameworkfiles in Link Binary With Librariesby clicking +do following.

第2步：现在，当您无法找到Crashlytics.framework并Fabric.framework在文件中Link Binary With Libraries通过点击+做以下。

2.1:Click on +button in Link Binary With Libraries.
2.2:Click on Add Other...button.
2.3:Now chose Crashlytic.frameworkand Fabric.frameworkfrom Podfolder - if using cocoapods, else choose both file from where you have downloaded it.

2.1：点击 中的+按钮Link Binary With Libraries。
2.2：点击Add Other...按钮。
2.3：现在选择Crashlytic.framework和Fabric.framework来自Pod文件夹 - 如果使用 cocoapods，否则从下载文件的位置选择这两个文件。

Step 3:Build Succeeded, Enjoy. :)

第 3 步：构建成功，享受。:)

For future reference, this can also happen if you link your test files to your app target.

为了将来参考，如果您将测试文件链接到应用程序目标，也会发生这种情况。

For example: https://github.com/realm/realm-cocoa/issues/1661

例如：https: //github.com/realm/realm-cocoa/issues/1661

Conversely to what I'L'I and user3517250 mention, the problem might also be that you have #importstatements that shouldn't be there.

与 I'L'I 和 user3517250 提到的相反，问题也可能是您有#import不应该存在的语句。

Xcode does infer the frameworks to link against from the #importstatements. If you import a framework that you don't link against, then you get this warning.

Xcode 确实从#import语句中推断出要链接的框架。如果您导入未链接的框架，则会收到此警告。

I had the same problem. Maybe I messed up the initial fabric install but once I added Fabric.framework to the list of frameworks (should be in the root folder of your app by default) everything worked.

我有同样的问题。也许我搞砸了最初的结构安装，但是一旦我将 Fabric.framework 添加到框架列表中（默认情况下应该在应用程序的根文件夹中），一切正常。
