生成错误时，交叉编译内核模块

Question

我试图交叉编译与规格的HelloWorld内核模块：

• 主持人：英特尔的x86 32位，Linux的3.0.0
• 目标：ARM机（鹦鹉AR.Drone的），Linux的2.6.27.47

我使用生成文件：

PWD := $(shell pwd) 
obj-m := test.o 
all: 
    $(MAKE) -C /path/to/kernel M=$(PWD) CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm modules 

哪里arm-none-linux-gnueabi-是手臂工具链的前缀。

使用来自kernel.org的2.6.27.47内核，这给了以下错误：

make -C /home/jens/linux-2.6.27.47 M=/home/jens/test CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm KBUILD_VERBOSE=1 modules

这是在这里，我卡住了。

Answer 1

我的问题是，像sessyargc.jp建议，由于配置错误。我已经应用了默认配置，而我应该使用特定于手臂的配置。使用这个，编译问题解决了。
