我在为 lineageos 项目构建 ROM 时遇到以下异常，需要一些帮助来诊断和解决问题：

In file included from device/lenovo/tb8504f/camera/QCamera2/util/QCameraDisplay.cpp:53:
In file included from system/core/libutils/include/utils/Looper.h:25:
bionic/libc/include/sys/epoll.h:67:8: error: redefinition of 'epoll_event'
struct epoll_event {
       ^
out/target/product/tb8504f/obj/KERNEL_OBJ/usr/include/linux/eventpoll.h:59:8: note: previous definition is here
struct epoll_event {
       ^

产生 1 个错误。

我通过从包含以下检查的不同内核版本借用代码来解决此问题

#ifdef __KERNEL__

完整片段如下：

#ifdef __KERNEL__
struct epoll_event {
struct epoll_event {
    __u32 events;
    __u32 events;
    __u64 data;
    __u64 data;
@@ -73,4 +74,5 @@ static inline void ep_take_care_of_epollwakeup(struct epoll_event *epev)
    epev->events &= ~EPOLLWAKEUP;
    epev->events &= ~EPOLLWAKEUP;
}
}
#endif
#endif
#endif /* __KERNEL__ */
