编的一个驱动，用的是2.6.22内核，交叉编译器是arm-linux-gcc 3.4.1。 下面是我的makefile文件： KERNELDIR :=/home/arm/linux-2.6.22.19 PWD :=$(shell pwd) CFLAGS =-D__KERNEL__ -DMODULE -I$(KERNELDIR)/include/ CROSS_COMPILE =/home/arm/3.4.1/bin/arm-linux- CC =$(CROSS_COMPILE)gcc obj-m := mydev_driver.o mydev_driver.o : s3c2440_mydev.o $(CC) $(CFLAGS) -c $^ -o $@ modules: $(MAKE) -C $(KERNELDIR) M=$(PWD) modules modules_install: $(MAKE) -C $(KERNELDIR) M=$(PWD) modules_install clean: rm -rf *.o *.ko *.mod.o *.mod.c make的时候，提示的错误信息如下： debian:/home/arm-drivers/mydev-drviver# make /home/arm/3.4.1/bin/arm-linux-gcc -D__KERNEL__ -DMODULE -I/home/arm/linux-2.6.22.19/include/ -c -o s3c2440_mydev.o s3c2440_mydev.c In file included from /home/arm/linux-2.6.22.19/include/linux/notifier.h:14, from /home/arm/linux-2.6.22.19/include/linux/memory_hotplug.h:7, from /home/arm/linux-2.6.22.19/include/linux/mmzone.h:466, from /home/arm/linux-2.6.22.19/include/linux/gfp.h:4, from /home/arm/linux-2.6.22.19/include/linux/slab.h:14, from /home/arm/linux-2.6.22.19/include/linux/percpu.h:5, from /home/arm/linux-2.6.22.19/include/asm-generic/local.h:4, from /home/arm/linux-2.6.22.19/include/asm/local.h:1, from /home/arm/linux-2.6.22.19/include/linux/module.h:19, from s3c2440_mydev.h:7, from s3c2440_mydev.c:1: /home/arm/linux-2.6.22.19/include/linux/rwsem.h:24:65: asm/rwsem.h: No such file or directory In file included from /home/arm/linux-2.6.22.19/include/linux/memory_hotplug.h:7, from /home/arm/linux-2.6.22.19/include/linux/mmzone.h:466, from /home/arm/linux-2.6.22.19/include/linux/gfp.h:4, from /home/arm/linux-2.6.22.19/include/linux/slab.h:14, from /home/arm/linux-2.6.22.19/include/linux/percpu.h:5, from /home/arm/linux-2.6.22.19/include/asm-generic/local.h:4, from /home/arm/linux-2.6.22.19/include/asm/local.h:1, from /home/arm/linux-2.6.22.19/include/linux/module.h:19, from s3c2440_mydev.h:7, from s3c2440_mydev.c:1: /home/arm/linux-2.6.22.19/include/linux/notifier.h:62: error: field `rwsem' has incomplete type In file included from /home/arm/linux-2.6.22.19/include/linux/sched.h:51, from /home/arm/linux-2.6.22.19/include/asm/uaccess.h:14, from s3c2440_mydev.h:13, from s3c2440_mydev.c:1: /home/arm/linux-2.6.22.19/include/linux/jiffies.h:33:3: #error You lose. /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if /home/arm/linux-2.6.22.19/include/linux/jiffies.h:225:31: division by zero in #if In file included from /home/arm/linux-2.6.22.19/include/asm/uaccess.h:14, from s3c2440_mydev.h:13, from s3c2440_mydev.c:1: /home/arm/linux-2.6.22.19/include/linux/sched.h:339: error: field `mmap_sem' has incomplete type In file included from mac_headers.h:66, from s3c2440_mydev.h:33, from s3c2440_mydev.c:1: 2440_headers/2440lib.h:19:1: warning: "min" redefined In file included from /home/arm/linux-2.6.22.19/include/linux/spinlock.h:53, from /home/arm/linux-2.6.22.19/include/linux/module.h:9, from s3c2440_mydev.h:7, from s3c2440_mydev.c:1: /home/arm/linux-2.6.22.19/include/linux/kernel.h:285:1: warning: this is the location of the previous definition In file included from mac_headers.h:66, from s3c2440_mydev.h:33, from s3c2440_mydev.c:1: s3c2440_mydev.c: At top level: s3c2440_mydev.c:225: error: storage size of `s3c2440_mydev_fops' isn't known make: *** [s3c2440_mydev.o] Error 1 还有一些warning没列出来。 s3c2440_mydev.h中包含的前几个头文件是： #include <linux/init.h> #include <linux/module.h> #include <linux/errno.h> #include <linux/kernel.h> #include <asm/io.h> #include <asm/uaccess.h> #include <asm/hardware.h> 我已经指定了内核源码的路径了，为什么会有这些错误呢？提示的错误都是在发生在内核代码里面。 2.6下驱动编译还能用-D__KERNEL__ -DMODULE选项吗？我把这个选项去掉错误就更多了。 大家帮忙看看，谢谢！

你是想变成可加载的内核模块么?这样试一下: make -C/kernel_path SUBDIRS=$PWD modules
jennymasar机器人#2 · 2009/6/24
我原来的makefile里有 modules: $(MAKE) -C $(KERNELDIR) M=$(PWD) modules 是不是差不多？ 我感觉问题应该出在这里： obj-m := mydev_driver.o mydev_driver.o : s3c2440_mydev.o $(CC) $(CFLAGS) -c $^ -o $@ 如果我这样写obj-m := s3c2440_mydev.o ，就可以生成 s3c2440_mydev.ko文件。 要编译的模块涉及到多个源文件，各源文件之间又有些依赖关系，应该怎么来写？ 【 在 lester98 的大作中提到: 】 : 你是想变成可加载的内核模块么?这样试一下: : make -C/kernel_path SUBDIRS=$PWD modules

kerneldir指定路径中的内核是经过正确配置和编译的吗？ 确认一下报错提到的那几个.h文件的确存在与相应的目录下
hobby机器人#4 · 2009/6/24
此外，我用过的makefile如下，倒是比较简单，就一个.c和一个.h，仅供参考 -------------------------------------------------------------------------------------------------------------- # Standard Makefile patten when compile extern module in 2.6 Kernel # Extern module means: moudles not stored in code tree #edit by hobby obj-m := netdrv.o netdrv-objs := vsc7398drv.o #The code tree path KERNELDIR = /usr/src/linux-2.6.13 #The crruent dir PWD := $(shell pwd) #the cmd executed when type "make" default: $(MAKE) -C $(KERNELDIR) M=$(PWD) modules #the cmd executed when type "make clean" clean: rm -rf *.o *.ko *.mod.c rm: rm -rf *.c *.h *.o *.ko *.mod.c --------------------------------------------------------------------------------------------

我按照hobby的模板，没有上面的错误了，主要是之前 obj-m := mydev_driver.o mydev_driver.o : s3c2440_mydev.o $(CC) $(CFLAGS) -c $^ -o $@ 改成 obj-m := mydev_driver.o mydev_driver-objs := a.o b.o c.o

现在遇到一个新问题，我在a.h里定义了一些全局变量，在a.c中会用到。 make的时候会提示 WARNING : “…” […] is COMMON symbol 但是还可以生成.ko文件。 insmod的时候，提示 please compile with -fno-common，加载失败。 应该怎么告诉make compile with -fno-common？怎么把这个参数传给make？感觉这个应该是gcc的参数？ 还有一点不太明白，一个make命令执行过程中什么时候编译？什么时候连接？

那全局变量一般在哪定义？我一直都这么用[em9] 【 在 lester98 的大作中提到: 】 : 为什么要在.h里定义全局变量?非得这样不可吗?这个习惯非常不好啊.
