內核模塊編譯出錯,高分求教大家幫忙

簡單一個Hello Wo r l d 的L i n u x內核模塊,可是編譯的時候就是出錯 程序如下: hello.c #include /* We're doing kernel work */ #include /* Specifically, a module */ /* Initialize the module */ int init_module() { printk("Hello, world - this is the kernel speaking\n"); /* If we return a non zero value, it means that init_module failed and * the kernel module can't be loaded */ return 0; } /* Cleanup - undid whatever init_module did */ void cleanup_module() { printk("Short is the life of a kernel module\n"); } Makefile如下: # Makefile for a basic kernel module CC = gcc MODCFLAGS := -O6 -Wall -DCONFIG_KERNELD -DMODULE -D__KERNEL__ -DLinux hello.o : hello.c /usr/include/linux/version.h $(CC) $(MODCFLAGS) -c hello.c

出錯: gcc -O6 -Wall -DCONFIG_KERNELD -DMODULE -D__KERNEL__ -DLinux -c hello.c in file included from /usr/include/linux/module.h:20 from hello.c:2 /usr/include/asm/module.h:56:2: #error unknown processor family make: *** [hello.o] error 1
