Did you make sure you are exporting the symbols properly in the code?

Hi all,
I am trying to write a kernel module that shares some data with a
userland process using shared memory.
The kernel module compiles with some warnings:
WARNING: "sys_shmat"
[/home/lnookx/shared_memory_tests/module/shmem_server_module.ko]
undefined!
WARNING: "sys_shmget"
[/home/lnookx/shared_memory_tests/module/shmem_server_module.ko]
undefined!
and when I try to load the kernel module I get:
insmod: error inserting './shmem_server_module.ko': -1 Unknown symbol in
module
and in dmesg I see:
shmem_server_module: Unknown symbol sys_shmat
shmem_server_module: Unknown symbol sys_shmget
Has anyone else seen these errors, and knows how to correct them?
Thanks,
lee
