Hello all,
When I try to "insmod" on a char device driver, it gives me the following errors.

"unresolved symbol create_proc_entry"
"unresolved symbol remove_proc_entry"

I am using Linux 2.4 Kernel on an ARM processor.

Can someone give me some suggestions on how to solve the problem?

Thanks.

hi,
To use any function in kernel module it has to be exported by the kernel or other module.
It might mean that the proc filesystem module is not loaded in kernel.

is your proc interface working properly?
try with ls /proc


if you get items like 1, 1234 cpuinfo etc, then it is working.

then try running my program, i wrote in this thread.

Do you have a reason for not using modprobe instead of insmod? Generally, modprobe resolves problems like yours. insmod is the bottom-level command in the chain, usually only used by scripts nowadays.
