xmake编译失败

[sonneImmer]

本机环境gcc版本为11.3.0，clang版本为11.0.0
git clone到本地后，进入文件夹执行xmake命令，出现如下报错信息

请问我这个地方是哪里出了问题呀？是gcc版本不支持的原因么？还是clang没配置好的问题呀？

目测是使用了 master 分支的源文件， 同时你的 default CC 是 clang。 clang 11.0 未经过测试， 可能无法满足最低编译器版本要求。

1. 切换到 dev 分支， 执行xmake 进行编译， 如果失败
2. 设置 xmake.lua 中 AyanConfig.Compilation.ToolChain 值为 "gcc", 重新使用 xmake 命令进行编译。
