问题
在过去的几周里，我一直在做一个基于Intel ISA-L库的纠删编码项目。
一切都很顺利，因为我只是调试了一段时间，然后我离开了大约一天的项目。我返回继续调试，没有对代码或我的Macbook（据我所知）进行任何更改，我试图再次编译代码作为调试过程的一部分，我得到了以下错误：

我已经尝试了我在Stack Overflow和其他在线资源上看到的几个潜在的解决方案，但没有一个有效。我还尝试在标准ISA-L库上编译代码，而不向其中添加任何额外的代码，但出现了同样的问题。
附加信息：
- 我正在开发一款2020年的MacBook Pro，它运行在macOS Monterey 12.5上，采用M1 Apple芯片。
- 下面是
clang --version的输出：
Apple clang version 13.1.6 (clang-1316.0.21.2.5)
Target: x86_64-apple-darwin21.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin型
- 下面是
echo $PATH的输出：
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin型
- Makefile非常复杂，我认为它是由英特尔ISA-L库中的某些代码自动生成的，所以我没有在这里介绍它，但我希望这不是我的情况所特有的问题，并且有一个通用的修复方法可以适用于许多情况。
- 如果需要其他细节，请告诉我。

我在将cmake更新到版本3.24.2后解决了这个问题。

我找到了一个解决方案，帮助我解决了这个问题（尽管它发现了一个更深层次的不相关的bug），我认为这可能对其他人有帮助。
显然，由于我在M1 MacBook Pro上运行，
clang --version的输出应该是arm64-apple-darwin21.6.0而不是x86_64-apple-darwin21.6.0。运行命令
arch也返回i3864而不是arm64，这是一个问题。为了解决这个问题，我运行了以下命令：

我不确定这是一个彻底的解决方案还是只是一个快速修复，但在重新启动后，我得到了与ARM的编译。

我也遇到过类似的问题（使用mpicc），我通过使用选项arch arm 64更改clang的架构解决了这个问题。您可以通过输入clang -arch arm 64--version（或mpicc -arch arm 64--version，在我的例子中）来检查更改。
