我正在尝试使用规范交叉编译helloworld内核模块：
我正在使用makefile：
PWD := $(shell pwd)
obj-m := test.o
all:
$(MAKE) -C /path/to/kernel M=$(PWD) CROSS_COMPILE=arm-none-linux-gnueabi- ARCH=arm modules
其中arm-none-linux-gnueabi-是arm工具链的前缀。
使用kernel.org的2.6.27.47内核，会出现以下错误：
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

就在这里，我被困住了。
答案 0 :(得分：1)
我的问题是，就像sessyargc.jp建议的那样，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arm的配置。使用它，解决了编译问题。
