socket.h missing on debian based distributions

[yangyzulu]

My TP-Link wn823n wifi adapter got very weak signal. It using rtl8xxxu driver now, so I try to install rtl8192eu to make it better. I'm using Ubuntu mate 16.04 kernel 4.14 on an odroid ux4 which has armv7l arch, but there are no platfrom in makefile that I can choose. What can I do?

I am facing the same problem. Did you find a solution/alternative after this?

Hi @shreyase99

Try sudo apt install libc6-dev

I have tried this already. I did not work out

~~socket.h, for some reason, is missing from your kernel headers. Perhaps install another kernel version or flavor (rt?) plus headers to see if it comes with socket.h~~

socket.h should come with libc-dev package, maybe install that with libc6-dev?

After that run
ls /usr/include/sys/socket.h
and see if it outputs a line
