Hi all,
I am using fedora linux 2.6.9-1.667 for developing kernel module .

i am exporting one function by using export symbol from one module and trying to call that exported function in to second module but whenever i am compiling the second module i am getting msg as follows

*** Warning: "unregister_sd_host_device" [/root/sd_stack/sd_host/sdhost.ko] undefined!

i tried to find the exported function in to the symbol table also but i am unable to find the symbole table also

i tried following thing

cat /proc/ksyms
cat /proc/kallsyms

i am unable to understand what is happening here can anyone help me to solve this proble as i am little bit new to fedora linux enviornment.

any help is greatly appreciated.
