前言

买了新电脑，在搭建环境安装keystone-engine时出现报错，之前在13.3从来没有遇到过，有点不知所措，不过有问题总得要解决的，虽然我直接将旧电脑的IDA搬运了过来，keypatch勉强能用，但是总感觉不舒服，经过一番google后，找到了问题的所在。

报错信息如下：


    CMake Error at /usr/local/Cellar/cmake/3.13.2/share/cmake/Modules/CMakeTestCCompiler.cmake:52 (message):
      The C compiler

        "/Library/Developer/CommandLineTools/usr/bin/cc"

      is not able to compile a simple test program.

      It fails with the following output:

不过最关键就是一句话ld: warning: The i386 architecture is deprecated for macOS (remove from the Xcode build setting: ARCHS)

xcode不支持i386，讨论贴在这

主要的意思就是说mojave 系统默认安装的xcode-select工具是不支持i386的，为了顺利的编译我们需要安装mac13.3的xcode-select套件。

在此下载安装

选择合适版本的xcode-select commandline 安装即可

我这里安装的是
Command_Line_Tools_macOS_10.13_for_Xcode_10.1.dmg

然后我们还需要安装xcode，然后在xcode中选择版本。

总的下来最好的办法就是安装旧版的xcode。

然后你就晾凉了，我反正是折腾了半天最后也没个好结果，还是将就用下吧，只要IDA patch时不出问题就行。

各位师傅保重！

总结

所以仔细看报错信息，问题总是能解决的。

记录一下mac mojave 安装 keystone-engine 报错问题解决
