Problems with uaccsess.h

[Chun Chung Lo]

Hi,

Seems your makefile does not include all the kernel header ...

Please try to add this ' -I(linux kernel source path)/include ' to your makefile as CFLAGS.

Best regards,
Lo Chun Chung

Hi

when I compile my program i got this message

bash-2.05b# make
gcc -O2 -DMODULE -D__KERNEL__ -W -Wall -Wstrict-prototypes -Wmissing-prototypes -isystem /lib/modules/`uname -r`/build/include -c -o hello.o hello.c

These Header files I have include

#include <linux/module.h>  /* Needed by all modules */
#include <linux/kernel.h>  /* Needed for KERN_ALERT */
#include <linux/slab.h>
#include <linux/delay.h>
#include <linux/version>
#include <linux/init.h>
#include <linux/fs.h>


#include <asm/types.h>
#include <asm/mpc8260.h>
#include <asm/cpm_8260.h>
#include <asm/page.h>

#include <asm/uaccess.h>

My linux is 2.4.25
Need I a patch to correct this ?? I need the funktion copy_to_user.

Regards
Fred
