【问题描述】：
我似乎找不到关于这个错误的太多信息。我有一个 C++ 代码库，我交给我的教授，它有一个构建脚本，可以安装柯南，然后安装柯南的依赖项。我最初在 Windows 上编写了代码库，但它在 github 上的 ubuntu:latest CI 上运行良好。它在我的本地机器上的ubuntu:latest docker 容器中也可以正常工作，我也将它移植过来。我的本地 docker 容器说它是ubuntu 20.04。我的教授有一个ubuntu 20.04 和一个ubuntu 20.10，都得到同样的错误，这是他们的构建日志

我确实发现我在使用gcc 9.3.0，而他们正在使用gcc 10.2.0，所以我更新了，更改了柯南配置文件，删除了构建文件，在容器上重新安装了deps和所有东西，它仍然可以构建。
如您所见，它在boost::asio 头文件中出现error: ‘#pragma’ is not allowed 错误。我真的不确定 github 和本地 docker 使用相同版本的 Ubuntu 构建良好的问题是什么。 GCC、cmake 和柯南也一样。我真的很困惑。我确实知道一些部门使用 glibc 和一些使用 newlib，从他告诉我的情况来看，他们似乎确实更新了他们的柯南个人资料，那里可能有问题吗？他们安装 GCC 会不会有问题？非常感谢任何帮助！
