內(nèi)核模塊編譯出錯(cuò)

rainballdh

我是安裝書(shū)上照搬下來(lái)的：
OS:CENTOS 4.5
KERNEL:2.6.9-42.ELsmp

Makefile:

1. 
   
2. # Makefile2.6
   
3.         obj-m := hellomod.o
   
4.         CURRENT_PATH := $(shell pwd)
   
5.         LINUX_KERNEL := $(shell uname -r)
   
6.         LINUX_KERNEL_PATH := /lib/modules/$(LINUX_KERNEL)/build
   
7. all:
   
8.         make -C $(LINUX_KERNEL_PATH) M=$(CURRENT_PATH) modules
   
9. clean:
   
10.         make -C $(LINUX_KERNEL_PATH) M=$(CURRENT_PATH) clean
    

復(fù)制代碼

編譯的時(shí)候提示：

1. 
   
2. make -C /lib/modules/2.6.9-42.ELsmp/build M=/root/c_dir/hellomode modules   
   
3. make[1]: Entering directory `/usr/src/kernels/2.6.9-42.EL-smp-i686'
   
4. make[2]: *** No rule to make target `/root/c_dir/hellomode/hellomod.c', needed by `/root/c_dir/hellomode/hellomod.o'.  Stop.
   
5. make[1]: *** [_module_/root/c_dir/hellomode] Error 2
   
6. make[1]: Leaving directory `/usr/src/kernels/2.6.9-42.EL-smp-i686'
   
7. make: *** [all] Error 2
   

復(fù)制代碼

make file 的問(wèn)題吧？
將make -C $(LINUX_KERNEL_PATH) M=$(CURRENT_PATH) modules修改為下面的看看（clean 也有問(wèn)題）：
$(MAKE) -C $(LINUX_KERNEL_PATH) M=$(CURRENT_PATH) modules

錯(cuò)誤還是一樣
不是makefile的問(wèn)題

貼給LZ一個(gè)LDD3上常用的Makefile，試一下好用不。偶現(xiàn)在自己寫(xiě)模塊，基本都用這個(gè)Makefile。

# To build modules outside of the kernel tree, we run "make"
# in the kernel source tree; the Makefile these then includes this
# Makefile once again.
# This conditional selects whether we are being included from the
# kernel Makefile or not.
ifeq ($(KERNELRELEASE),)

    # Assume the source tree is where the running kernel was built
    # You should set KERNELDIR in the environment if it's elsewhere
    KERNELDIR ?= /lib/modules/`uname -r`/build
    # The current directory is passed to sub-makes as argument
    PWD := $(shell pwd)

modules:
        $(MAKE) -C $(KERNELDIR) M=$(PWD) modules

modules_install:
        $(MAKE) -C $(KERNELDIR) M=$(PWD) modules_install

clean:
        rm -rf *.o *~ core .depend .*.cmd *.ko *.mod.c .tmp_versions

.PHONY: modules modules_install clean

else
    # called from kernel build system: just declare what our modules are
    obj-m := netbase.o
endif

替換

    obj-m := netbase.o

中的netbase.o為你自己的即可。偶用起來(lái)沒(méi)有問(wèn)題

謝謝各位，是我自己不夠細(xì)心

Godbach

呵呵，LZ可否分享一下你的問(wèn)題所在，讓別人在以后也可以注意啊。

Godbach

是參與編譯的文件位置不對(duì)嗎

Makefile里面寫(xiě)的是：
obj-m := hellmod.o
而我的C文件是hellomod.c
不一致，導(dǎo)致上買(mǎi)你的錯(cuò)誤。自己太粗心了

呵呵，是啊。有時(shí)總是被這樣的錯(cuò)誤困擾半天。 另外，你1樓上寫(xiě)的又是正確的吧。
