XCode 7.3.1，“架构 arm64 的未定义符号" [英] XCode 7.3.1, "Undefined symbols for architecture arm64"

问题描述

我有一个 Swift 2.x 应用程序，我试图将这个 Obj-C 库用于:https://github.com/lmirosevic/GBPing

I have a Swift 2.x app that I am trying to use this Obj-C library with: https://github.com/lmirosevic/GBPing

我已将头文件添加到我的桥接头中:

I have added the header file to my bridging header:

#import "GBPing-master/GBPing/GBPing.h"

当我尝试构建时，出现此链接器错误:

When I am trying to build, I get this linker error:

架构 arm64 的未定义符号:_OBJC_CLASS_$_GBPing"，引用自:在Pinger.o_OBJC_CLASS_$_GBPingSummary"中为__ObjC.GBPing输入元数据访问器，引用自:为 __ObjC.GBPingSummary 在 Pinger.old 中输入元数据访问器:找不到架构 arm64 clang 的符号:错误:链接器命令失败，退出代码为 1(使用 -v 查看调用)

Undefined symbols for architecture arm64: "_OBJC_CLASS_$_GBPing", referenced from: type metadata accessor for __ObjC.GBPing in Pinger.o "_OBJC_CLASS_$_GBPingSummary", referenced from: type metadata accessor for __ObjC.GBPingSummary in Pinger.o ld: symbol(s) not found for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

我搜索并找到了一些关于未找到架构 arm64 的符号"的帖子，但未能使其正常工作.我对 iOS 开发很陌生，所以 XCode &Swift 对我来说都很陌生(而且我从未使用过 Obj-C).

I have searched for and found some posts about "symbols not found for architecture arm64" but have not been able to get this working. I am quite new to iOS development, so XCode & Swift are both fairly new to me (and I have never done Obj-C).

因为我只使用了这个库中的 .h 和 .m 文件，所以不是应该从这些文件中构建所需的目标文件吗?那么为什么不支持 arm64，我该如何解决呢?

Since I am only using .h and .m files from this library, aren't the needed object files supposed to be built from these? So why is arm64 not supported and how can I fix it?

基本上，我只需要帮助让这个 GBPing 库在我的 Swift 应用程序中正确编译，以便我可以使用它...

注意:我的其他链接器标志"设置为空，但我确实尝试添加 $(inherited)，但没有帮助.我不想删除 arm64 作为架构.最后，这是一款企业应用，只能在 iPad Air 2 和 iPad Mini 4(iOS 9.2 及更高版本)上运行

Notes: My "Other Linker Flags" setting is empty, but I did try adding $(inherited), which did not help. I do not want to remove arm64 as an architecture. Lastly, this is an Enterprise app that will only run on iPad Air 2 and iPad Mini 4 (iOS 9.2 and up)

推荐答案

检查您的目标构建阶段 -> 编译源以确保为 GBPing.m 和 GBPingSummary.m 编译.

Check your target Build Phases ->Compile Sources to make sure did compile for GBPing.m and GBPingSummary.m.

如果没有，只需将所有库 .m 文件添加到编译源.

if not, just add all library .m file to Compile Sources.
