我在 Xcode 中收到包含此消息的编译时错误
clang:错误:链接器命令失败,退出代码为 1(使用 -v 查看调用)
This -v
显然是一个命令行选项。我以前遇到过这条消息,并且一直不知所措,不知道我能对此做什么,以及如果我对此无能为力,为什么会包含它。
如何使用 Xcode 中的选项来查看调用?
您可以添加-v
到项目设置中的“其他链接器标志”字段。在此处的测试项目中执行此操作会产生完整的链接器调用:
"/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld"
