i386 架构在 MacOS 错误中已弃用

Question

我对 Mac 环境完全陌生，而且只使用了几个小时。当我运行 shell 脚本时，出现以下错误 -

ld: warning: The i386 architecture is deprecated for macOS (remove from the Xcode build setting: ARCHS)
ld: warning: ignoring file /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd, missing required architecture i386 in file /Library/Developer/CommandLineTools/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd

如何从 Xcode 中删除 i386 架构？我该如何解决这个错误？

Answer 1

使用 xcode 9.4 或 9.4.1，这是支持 32 位构建的最后一个版本，并且在 Mojave 上有效。

Answer 2

所以问题是苹果已经取消了使用 xcode10 在 macos 上编译 32 位程序的能力

Answer 3

修改CMakeLists.txt删除i386字样 ;最后的 mac os 上不支持。 i386 软件符合要求
