dear all
I'm newbie on this. but i need the advise for this problem. sorry if this
already in archive

I had embedded system from vendor using ubuntu 7.  with kernel 2.6.20.4 the
system is on CF card
i need to have the bridge module on that systems, the problem there is no
compiler,etc. very minimum system
so what i did is install ubuntu on another PC and using exactly the same
kernel, gcc version etc to get the kernel with bridge module and then
copying all /boot folders and /lib/modules onto my embedded system

the bridge module get error: insmod: error inserting bridge.ko : unknown
symbol

at dmesg

bridge: Unknown symbol br_handle_frame_hook



is there any way to solve this problem, without rebuilding all OS on CF card

If the kernel itself was not built with bridging configured, then
the hook for the bridge won't be in the receive code in the kernel.

So basically you are out of luck, building bridge out of tree.
You need to get kernel source for the whole embedeed system, reconfigure
and rebuild.

thank you Stephen

yes i knew that this will be the only one solutions.
the problem that the embedded system which is on ubuntu 7.04 doesn;t have
any compiler or source kernel. do you have any tips or hints for this.
thanks
