Question

我为自己的内部使用构建了自己的pod。 pod spec lint工作正常但是当我试图实际使用它时，它给了我以下编译错误：

Undefined symbols for architecture armv7:

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我怀疑podspec中的框架设置不正确，因为这是我写的第一个pod，我可能会遇到一些错误。

提前致谢。

正式回答我发布的问题。我需要执行以下操作来修复它：

链接C ++标准库:(感谢@ H2CO3）
- 将s.library = 'stdc++'添加到 podspec
链接MediaPlayer框架:(感谢@ H2CO3）
- 将s.frameworks = 'MediaPlayer'添加到 podspec
CAStreamBasicDescription 的问题已通过以下答案修复：Trouble linking Tim Bolstad's Core Audio Example

使用自定义cocoapod会产生编译错误（架构armv7的未定义符号:)
