这个实例项目是必须要C++20是吧，编译报错提示g++: error: unrecognized command line option ‘-fcoroutines’
升级gcc12就编译通过了

不是。GCC 4.8以上，Clang 4以上，或VS2017以上带的MSVC都可以。

运行cmake的编译器和实际执行编译的编译器要保持一致。在cmake阶段会检测编译器功能。如果切换编译器要删除build目录里的CMakeCache.txt文件。否则某些检测的结果可能会被cmake认为未变化而不重新执行检测过程。

不太能理解你说的意思，我查了一下unrecognized command line option ‘-fcoroutines，说是需要C++20才能支持

这个选项如果在执行cmake的阶段检查出来发现不支持就不会加。

和

https://github.com/atframework/atframe_utils/actions/runs/1197439868

有各类编译环境的CI检查。

明白你的意思了，诡异的是我这个报错是在执行cmake的时候报错的，就是 sh cmake_dev.sh的时候

我修订下构建系统。CI里没有gcc 6的环境。可能gcc 6下cmake自带的检测有点问题。我自己patch一下吧，感谢反馈。
用gcc 8以上或者gcc 4.8应该是没问题的。
