在内核5.11上编译wanpiet驱动程序 [英] Compiling wanpipe driver on kernel 5.11
本文介绍了在内核5.11上编译wanpiet驱动程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在Ubuntu 21.04和内核v5.11上编译Sangoma的wantube驱动程序v7.0.32，以便与我的A200电话卡一起使用。该驱动程序旨在支持内核5.8。我已经成功地使用5.8内核构建了它，但我更希望能够继续使用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，无法解决如何在编译wanpie驱动程序时排除‘struct’和"；‘’struct FILE_OPERATION‘中没有名为’ioctl‘成员的字段的位置初始化错误。
以下是make的结果：

感谢任何帮助。
推荐答案
WANPIPE之前的代码仅适用于2.6.36或更低版本的内核。在ubuntu 21.04中，他们对WRT内核5.8做了一些修改。在5.8或更高的内核版本中，文件操作中没有ioctl函数指针。相反，他们使用的是unlock_ioctl。以下更改将消除该错误。你可以用同样的方法核对一下。谢谢！
