I tried to compile wireguard from source in armbian xenial with kernel 4.9.7. on a Banana Pro. After compiling and installing the resulting kernelmodule, modprobe fails: sudo modprobe wireguard modprobe: ERROR: could not insert 'wireguard': Exec format error dmesg shows: [ 5563.012529] wireguard: loading out-of-tree module taints kernel. [ 5563.013912] wireguard: unknown relocation: 102 On the wireguard list, one pointed out this might be related to old toolchain, so i checked: the installed gcc is: gcc version 5.4.0 20160609 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.4) and the mentiond gcc Version in dmesg is (gcc version 6.2.1 20161016 (Linaro GCC 6.2-2016.11) ) So do i need to crosscompile the module? I set up a crosscompile enviroment as described in the documentation, but its lacking hints about compiling external kernelmodules. Regards, Alexander Morlang
