- OpenWRT 18.06.1
- Raspberry Pi 2 B
- Kernel 4.9.120
Attempting to build a very simple hello world kernel module results in the following error:
# make make -C /lib/modules/4.9.120/build M=/c_programming/hellomodule modules make: *** /lib/modules/4.9.120/build: No such file or directory. Stop. make: *** [Makefile:6: all] Error 2
Makefile isn't a problem, since it works on Ubuntu just fine. What I've done so far:
- I've checked and the directory indeed is missing.
- Checked with
opkg find '*headers*'however there's no packages
linux-headers-<release>like on Ubuntu.
How should I proceed to actually build this thing ?
