Xcode 8.0更新后,架构arm64的重复符号

Question

我更新后,我得到重复的符号错误Xcode.(找到代码)有人也得到这个吗？怎么可以解决？

我试图-ObjC从"其他链接器标志"部分删除链接器标志,在导入后检查.m而不是.h,将"No Common Blocks"编译器设置切换为NO,我去了Targets -> Build Phases -> Compile源并且没有重复,尝试了所有没有结果.

还有其他想法吗？

Answer 1

下面补丁为我工作.. :)

代码建议使用警告标志并将GCC_NO_COMMON_BLOCKS设置为YES.

将其设置回NO解决了问题!

Answer 2

我终于找到了!您可以在Build设置中将enable testability设置为NO后进行编译.

来自Xcode 8发行说明:

启用Enable Testability构建设置后,Xcode 8会将-export_dynamic传递给链接器以保留所有全局符号以进行测试.这有效地覆盖了死代码剥离,这可能会暴露引用未定义符号的未使用函数的链接失败.如有必要,禁用可测试性将允许链接在没有源更改的情况下继续.(27684883)

当然,最好的办法是:a)删除导致链接器问题的未使用代码,或b)实际修复链接器问题.

Answer 3

我理解大多数人都是通过No Common Blocks或Dead Code设置来解决这个问题,但这实际上是真正问题的解决方法.在我的情况下,我使用的是一个Pod文件,它添加了我已经链接过的相同库,所以基本上我删除了我的Build Phases链接库中的重复文件,这些库已经在我的Pod文件中编译并且存档功能正常工作.
