[eepro100] Re: [newbie] Unresolved symbols

[Kallol Biswas]

Hi,
   I am new to linux kernel and modularization...

Did you check the exported symbols in kernel? I don't know
any utility to do it but you can use the following
program to find out the exported symbols:

#include <stdio.h>
#include <linux/module.h>

main()
{
struct kernel_sym *table;
int     num=0, i;

num = get_kernel_syms(NULL);

table = malloc(sizeof(struct kernel_sym) * num);

num = get_kernel_syms(table);

for (i=0; i < num; i++) {
        printf("value = 0x%x name %s\n", table->value, table->name);
        table++;
}

printf("NUM = %d\n", num);
}
