【问题描述】：
我正在尝试在带有内核 v5.11 的 Ubuntu 21.04 上编译 Sangoma 的 wanpipe 驱动程序 v7.0.32，以便与我的 A200 电话卡一起使用。该驱动程序是为支持内核 5.8 而编写的。我已经使用 5.8 内核成功构建了它，但希望能够继续使用 5.11 内核，这样我就不必降级我的生产服务器。
我缺乏 C++ 知识来解决如何在编译 wanpipe 驱动程序时解决“'struct' 中字段的位置初始化和“''struct file_operation' 没有名为 'ioctl' 的成员”错误。
这是make的结果：

感谢任何帮助。
【问题讨论】：
-
驱动程序似乎配置错误：它遵循分支
#else（并使用#define WAN_IOCTL ioctl)而Linux内核5.11 hasunlocked_ioctl方法，所以@987654328 @ 应该被定义。
