proble with MODULE_PARM()

[pratik]

Hello Friends

I'm using RH9 2.4 kernel and i've problem with module_param() function in the module.

i've declared one global variable say

static int x =1;

/*and the rest of the functions in the module*/

..........
.........

MODULE_PARM(x,"i");
.......
........
/*finish the code*/

but it is showing error in compiling like

"parse error before string constant "
warning : type defaults to 'int' in the declaration of module param
warning : data definition has no type or storage class

i've also tried

module_param(x, int);
but getting the same, "parse error before "int" "

please somebody get me out of this

Thanks in Advance,

Pratik H Pandya.

You are missing a vital argument to module_param(), which is the permissions mask for the sysfs entry:

static int x = 1;
module_param(x, int, S_IRUGO);

for example.

Does a 2.4 kernel have sysfs???
I doubt...
AFAIK, sysfs is introduced in 2.6

Also, AFAIK, RH9 uses version 2.4.18...
The source of 2.4.18 doesn't define module_param() at all...
Take a look at:
