按照IOS离线打包的教程进行打包，但一直报错：ld: symbol(s) not found for architecture x86_64
后按照网上一篇教程更改Architectures为32位的，更改之后可以在模拟器上跑起来了，但真机运行提示系统已经不支持32位的应用了，无奈之下改了回来，但一直报错：
ld: warning: could not create compact unwind for _ffi_call_unix64: does not use RBP or RSP based frame

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
请问这是什么原因？
