esp-idf安装后编译报错

[EvanYe]

我使用的是windows11，esp-idf-4.4版本的离线安装版，使用hello_world例程执行idf.py build 时报错，报错部分如下，说是sched_yield的问题不知到怎么解决，重新安装或者安装不同版本也是同样的错误，求各位大佬解答！！

这是部分日志，类似的错误重复了很多次。附件是完整日志。

他就说这东西，没有声明，既然是return 必定函数里，找找是不是 该变量的确没有声明。

可这个函数不是系统函数吗，我这个idf环境刚装的还是自带的例程为啥会少系统函数呀。。。。

找到原因了，是因为之前在系统中设置了环境变量 C_INCLUDE_PATH，删掉好了，感谢各位的建议。
