Eu tenho um dongle USB que tem o chipset RTL8188eu. Ele costumava trabalhar sem ter que fazer nada (ou seja, eu poderia apenas ligá-lo e ir embora).
Enquanto tentava instalar vários outros dongles USB, eu de alguma forma consegui deletar o driver para este dongle (no meu sistema, em /lib/modules/4.13.0-31-generic/kernel/drivers/staging/rtl8188eu ).
Eu tentei reconstruir isso (r8188eu.ko) imitando as etapas que usei para reconstruir meu btusb.ko (que também desapareceu):
tar -zxvf linux-4.13.tar.gz
cd ./linux-4.13/drivers/staging/rtl8188eu
make -C /lib/modules/$(uname -r)/build M=$PWD modules
Mas recebo este erro:
[van@van-t470p:rtl8188eu]$ make -C /lib/modules/$(uname -r)/build M=$PWD modules
make: Entering directory '/usr/src/linux-headers-4.13.0-31-generic'

Eu também tentei executar o nível de um único diretório:
cd .. make -C /lib/modules/$(uname -r)/build M=$PWD modules Mas isso também falhou:

Talvez os parâmetros do Makefile sejam diferentes para módulos wifi? Existe uma maneira de reconstruir meu r8188eu.ko ausente ou preciso reinstalar o sistema operacional?
