链接英特尔库以在 M1 Mac 上使用 Xcode 生成英特尔二进制文件

Question

I have 16" M1 Pro MacBook Pro. The third party C library (.a) was built with Intel Mac and there's absolutely no way to modify the code or rebuild with M1 Mac. The binary is x64 binary.

My project is using C++ and Objective-C++ (.mm) with Xcode. It is targeted for Mac app and not iOS. I want to link the C library to my project.

The linked library 'libkfunc64.a' is missing one or more architectures required by this target: arm64.

I checked similar question but it didn't work:

Can Xcode on m1 Mac build targeting Intel

What I want to do is to generate an Intel binary. I don't need a M1 binary or hybrid binary - I can run Intel binary on Rosetta 2 on M1 Mac.

I created a console-app with "-arch x86_64" option for LLVM C++ compiler and it worked. But I don't know how to pass that option on Xcode.

Please tell me how to do it. I am using Xcode 13.3.

Answer 1

Xcode - Targets - Build Settings Architectures （x86_64） or Excluded Architectures(arm64). I've only tested the opposite.
Arm64 required, no x86_64.
