核心模組的makefile的製作（多模組）

hello.c

#include#includemodule_license("gpl");

//module_author("cfc");
//module_description("hello linux");
//module_alias("a ****** module");
extern int add(int a,int b);
extern int sub(int a,int b);
static int __init hello_init()
static void __exit hello_exit()
module_init(hello_init);
module_exit(hello_exit);

calculate.c

#include#includemodule_license("gpl");

//module_author("cfc");
//module_description("hello linux");
//module_alias("a ****** module");
int add(int a,int b)
int sub(int a,int b)
static int __init sym_init()
static void __exit sym_exit()
module_init(sym_init);
module_exit(sym_exit);
export_symbol(add);
export_symbol(sub);

makefile

ifneq ($(kernelrelease),)	

obj-m := hello.o calculate.o
else 
kdir := /lib/modules/2.6.28/build 
all: 
make -c $(kdir) m=$(pwd) modules 
clean: 
rm -f *.ko *.o *.mod.o *.mod.c *.symvers 
endif

核心模組Makefile

前些天寫乙個驅動模組。竟然寫核心模組makefile時出了問題，於是將其總結下來，下次再用時拿過來改下就行了。general purpose makefile for linux kernel module by guoqingbo kern dir home gqb development lin...
