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

通过指令修改Makefile之后，我运行了“ make”命令并得到以下错误：

问题文件是rtw_br_ext.c，它使用Linux内核中的标头。因此，makefile中没有KBUILD标志。解决此问题的最佳方法是什么？

Answer 1

请勿更改make文件。无需进行更改即可运行文件，它将运行确定。在该Github网址上，没有更改Make文件的指令。
