Realtek固件安装错误

Question

我正在开发一个HC2，运行Debian9“拉伸”。

在我的日志中，我可以看到Wifi缺少一个司机：

usb 1-1: request_firmware(rtlwifi/rtl8192eu_nic.bin) failed

所以我安装了固件-realtek软件包。

apt install firmware-realtek

以下是安装的输出：

正如我所见，符号链接的创建失败了。

而且，很明显，我无法对模块进行调制：

root@ohc2:~# modprobe rtl8192eu
modprobe: FATAL: Module rtl8192eu not found in directory /lib/modules/4.14.141+

我已经试过清洗和重新安装它了。

我怎么才能解决呢？

谢谢

根据弗雷迪的评论，以下是答案：

安装所需的软件包来编译

apt update
apt install linux-headers-$(uname -r) git build-essential dkms -y

去拿文件

cd /tmp
git clone https://github.com/Mange/rtl8192eu-linux-driver.git
cd rtl8192eu-linux-driver

如果你像我一样，在一个HC2，你需要修改Makefile (https://github.com/diederikdehaas/rtl8812AU/issues/34)

nano Makefile

将参数CONFIG_PLATFORM_I386_PC更改为n，将参数CONFIG_PLATFORM_ARM_RPI更改为y

现在编译

dkms add .
dkms install rtl8192eu/1.0
modprobe 8192eu
