I've got a working Openwrt running on a orange pi r1, however no working wifi
driver comes with the img (openwrt).
The problem i encounter is the loading of module (cfg80211.ko), used for configuration purposes.
The module is build against:
linux-stable-4.14.34 with sunxi_defconfig after which I selected the cfg80211 from make menuconfig.
Compiler:
arm-linux-gnueabihf-gcc (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609
Loading the module on the orange-pi shows:
root@OpenWrt:/lib/modules/4.14.34# modprobe cfg80211.ko
[ 42.424100] cfg80211: Unknown symbol __put_net (err 0)
1 module could not be probed
- cfg80211
The kernel info:
root@OpenWrt:/lib/modules/4.14.34# cat /proc/version
Linux version 4.14.34 (buildbot@crazyhorse)
(gcc version 7.3.0 (OpenWrt GCC 7.3.0 r6727-38bd4e4))
#0 SMP PREEMPT Thu Apr 19 17:15:00 2018
My assumption was, that if i compile a module against the same version it should be able to be load it, ...
Any help or suggestions on how to compile/load module for an image that
was obtained (instead of build locally) would be much appreciated.
Could it be a name mangling issue due to the difference in compilers?

It may be not enough compiling a module to put in another kernel as you found out. You will have to install a new kernel + the new module.
