linux2.6下的设备驱动问题
2009年04月24日 14:49 发布者：chengnokia
这是C文件#include
#include
MODULE_LICENSE("Dual BSD/GPL");
static int hello_init(void)
{
printk(KERN_ALERT "hello,world\n");
return 0;
}
static void hello_exit(void)
{
printk(KERN_ALERT "Goodbye,cruel world\n");
}
module_init(hello_init);
module_exit(hello_exit);
~
下面是makefile
CC =/usr/local/arm/bin/arm-linux-gcc
KERNELDIR=/home/work/linux2.6
CFLAGS =-D__KERNEL__ -DMODULE -I$(KERNELDIR)/include -O -Wall
hello.hello.c
$(CC)$(CFLAGS) -g -c $<
clean:
这时报错：
/usr/local/arm/bin/arm-linux-gcc -D__KERNEL__ -DMODULE -I/home/work/linux2.6/include -O -Wall -g -c hello.c

回复1楼chengnokia：
#error "Unsupported AT91 processor"
楼主使用的处理器是AT91系列的吗?最好是找一个支持该处理器或开发板的Linux整个包,自己移植太累了
