我正在尝试针对文件系统上的任何源代码树编译模块,但Makefile出现问题。这是我针对指定内核使用的原始Makefile:
obj-m += new-mod.o all: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules clean: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
该Makefile可以正确编译,但目标是针对任何源代码树进行编译。我试过:
obj-m += new-mod.o
我以为假设了“全部:”,但出现错误:
make: *** No targets. Stop.
我还添加了:
all:
到Makefile中,除了错误消息外没有其他区别:
make: Nothing to be done for `all'
我尝试了很多文档,但是没有运气。我将不胜感激任何帮助。
goal is to have it compile against any source tree
你可以做到这一点 compiled source-code path
compiled source-code path
只需更换 make -C /lib/modules/$(shell uname -r)/build M=$PWD modules
make -C /lib/modules/$(shell uname -r)/build M=$PWD modules
有了这个
make -C <path-to-compiled-src-code> M=$PWD modules
make -C /home/vinay/linux-3.9 M=$PWD modules
试试下面的makefile
Makefile –
# if KERNELRELEASE is defined, we've been invoked from the # kernel build system and can use its language. ifneq (${KERNELRELEASE},) obj-m := new-mod.o # Otherwise we were called directly from the command line. # Invoke the kernel build system. else KERNEL_SOURCE := /usr/src/linux PWD := $(shell pwd) default: ${MAKE} -C ${KERNEL_SOURCE} SUBDIRS=${PWD} modules clean: ${MAKE} -C ${KERNEL_SOURCE} SUBDIRS=${PWD} clean endif
在上面,您可以将KERNEL_SOURCE := /usr/src/linux-> 更改为->您的sr代码KERNEL_SOURCE := <path to compiled-src-code>
KERNEL_SOURCE := /usr/src/linux
KERNEL_SOURCE := <path to compiled-src-code>
