Question

我有一个带有 Pugpig 框架的应用程序和这个错误：

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_KGLocalFileDataSource", referenced from:
      objc-class-ref in SolitairViewController.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我的架构是armv7 arm64。

如果我删除 arm64 它可以工作，但是当我在 itunes connect 上提交应用程序时它是无效的二进制文件。

我试图改变我的 pugpig 框架，我明白了：

Answer 1

听起来您需要更新版本的 Pugpig.framework。 2.4 及以上版本支持 64 位，https://pugpig.zendesk.com/hc/en-us/articles/202429446-Release-Notes#2.4.0

在回答您修改后的问题时，链接器错误是由缺少依赖项引起的。在第一种情况下，它与您没有带有 64 位切片的 Pugpig 版本有关，在后一种情况下，它与目标构建设置中缺少 frameworks/libraries 有关。具体在您的情况下，您需要添加

-lz -lxml2 -weak_framework Twitter -weak_framework Social

到 "Other Linker Flags" 下目标的构建设置。

如果您搜索缺失的符号，您通常会找到每个符号的现有答案。例如参见 [=15=].
