交叉编译2.6驱动无法通过

Question

各位大哥，小弟正在从pc上编译驱动到arm板，但是在交叉编译这一步怎么也过不去，请各位大侠帮忙指点一下！
编译器arm-linux-gcc-3.4.1，试验代码hello.c照抄ldd3的代码：
#include <linux/init.h>
#include <linux/module.h>
//MODULE_LICENSE("Dual BSD/GPL");

static int hello_init(void)
{
        printk("Hello, worldn");
        return 0;
}

static void hello_exit(void)
{
        printk("Goodbye, cruel worldn");
}

module_init(hello_init);
module_exit(hello_exit);
MODULE_LICENSE("GPL");

编译方法一：利用Makefile，内容如下：
armgcc1 = /usr/local/arm/3.4.1/bin/arm-linux-gcc
INCLUDELDIR = /usr/local/arm/3.4.1/arm-linux/sys-include
NOWFLAG = -I$(INCLUDELDIR)
hello.o: hello.c
default:
                $(armgcc1) -mcpu=arm920  $(NOWFLAG) --host=arm-linux -c hello.c
显示cc    -c -o hello.o hello.c，生成的hello。o，用file ./hello.o查看是./hello.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped
在2410上insmod hello。o提示如下：hello.o: ELF file hello.o not for this architecture

编译方法2：直接ARM-GCC
#/usr/local/arm/3.4.1/bin/arm-linux-gcc -c hello.c
却得到一大堆include file的错误，错误完整内容如下：

小弟我分析了一下，可能是因为include module。h，因为我又编译了更为简单的hello。c
#include <stdio.h>
int main() { printf("Hello, world!n"); return 0; }
这一次顺利通过，而且可以在arm上运行

各位大侠，请帮忙分析一下，或者提供你们在编写drivers for 2.6所使用的交叉编译方法，多谢！

Answer 1

lz最好先了解一下用户态编程和核心态编程的区别。

Answer 2

多谢，回头马上调试，

致谢！！！！

Answer 3

2.6的内核,那你的Makefile有错,见ldd3

试下这个Makefile

2. obj-m :=hello.o
3. KERNELDIR ?= /usr/local/arm/3.4.1/arm-linux/
4. PWD :=$(shell pwd)
6. all:
7.                 $(make) -C $(KERNELDIR) M=$(PWD)

复制代码

用这个命令make

2. make ARCH=arm CROSS_COMPILE=/usr/local/arm/3.4.1/bin/arm-linux-

复制代码
没有环境测试,不知是否正确

Answer 4
