I want to install batctl-2016.4 tool in my embedded Linux 4.9.11. I checked that this version is compatible with my firmware. I unzipped the .tar file but, now I do not know how to do. I try to execute Makefile but, it does not work.
You should only need to opkg install batctl-full
BATMAN tends to be unable to interoperate between versions, so always use the same version including every node. Since much of BATMAN is in the kernel, this also means you need roughly the same kernel version on all nodes.
