linux - RTL8821CE(wifi)驱动安装问题: KBUILD_MODNAME

Question

我为运行 Linux Mint 19 的新 HP 17z 笔记本电脑下载了以下驱动程序:https://github.com/endlessm/linux/tree/master/drivers/net/wireless/rtl8821ce

根据指令修改生成文件后，我运行了“make”命令并收到以下错误:

问题文件是 rtw_br_ext.c，它使用 Linux 内核的 header 。所以 makefile 中没有 KBUILD 标志。解决此问题的最佳方法是什么？

Answer 1

不要更改 make 文件。 在不进行更改的情况下运行该文件，它将运行正常。 在那个 Github url 上，没有更改 make 文件的说明。
