Xcode 10 beta错误：链接器命令失败，退出代码为1

Question

This is the complete error:

ld: library not found for -lstdc++.6 clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have no idea what is this about, I'm using Xcode 10 beta, and iOS 11.4.1, I have no "pods" project or anything like that, when I try to run the command:

pod install

I get the command not found.

I'm not using any additional tools or anything, so I'm only using npm and xcode command line commands.

Thanks.

Answer 1

(I post the solution here for all those who googled "cocoapods lstdc xcode 10" since this is the first page that hits.)

If you are using cocoa pods and got a similar error then the solution is to delete -l"stdc++.6" from your xcconfig files. Now build and run. Xcode10 build should succeed now :)

Cocoa pods is for some reason adding stdc so it gets linked, but that is not be needed and Xcode10 does not have that library anymore.

Answer 2

Libstdc++ was deprecated, the support was removed from the iOS 12 simulator (not for device).

One of the library in the pod file have a dependency builded with libstdc++, you can try to find a more recent version builded with the libc++.
