Hi all :")
i have trouble
Code:
usr/lib/gcc/arm-linux-gnueabihf/4.7/include/stdint.h:3:26: error: no include path in which to search for stdint.h
I try write LKM with <bcm2835.h> (
http://www.airspayce.com/mikem/bcm28...8h_source.html)
my make file is
Code:
obj-m := gpio.o
LIBS = -lbcm2835 -lrt
DEPS=bcm2835.h
all:
make -C /lib/modules/3.12-1-rpi/build M=/home/pi/module modules
my example code
Code:
#include <linux/init.h>
#include <linux/module.h>
#include <linux/kernel.h>
#include <bcm2835.h>
MODULE_LICENSE("Dual BSD/GPL");
static int hello_init(void) {
printk("<1> Hello world!\n");
return 0;
}
static void hello_exit(void) {
printk("<1> Bye, cruel world\n");
}
module_init(hello_init);
module_exit(hello_exit);
i read somwhere kernel modules, and thus have no access to glibc (or its headers).
Code:
make -C /lib/modules/3.12-1-rpi/build M=/home/pi/module modules
