如何获取对Xcode“clang”的调用编译时错误？ [英] How to get invocation for Xcode "clang" compile-time error?

问题描述

我在Xcode中得到包含此消息的编译时错误

I get a compile-time error in Xcode that includes this message

clang：error：linker command failed with exit code 1使用-v查看调用）

clang: error: linker command failed with exit code 1 (use -v to see invocation)

这个 -v -line选项。我之前遇到过这个消息，对于我可以做些什么以及为什么它包括，如果我不能做任何事情，总是失去。

This -v is evidently a command-line option. I've run into this message before and have always been at a loss as to what I can do about it and why it's included if I can't do anything about it.

推荐答案

您可以添加 -v 添加到项目设置中的其他链接器标志字段。在测试项目中这样做会产生完整的链接器调用：

You can add the -v to the "Other Linker Flags" field in the project settings. Doing so in a test project here yields the complete linker invocation:

 "/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ld"
 -demangle
 -dynamic
 -arch x86_64
 -macosx_version_min 10.8.0
