Error while compiling Linux kernel for ARM

问题

I cloned the kernel from

 https://github.com/torvalds/linux.git

Then tried to compile it as follows

#make menuconfig

menu config screens shows up. Without making any changes I save the config that generated .config file

#make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

I get the following error. Please advise

In file included from arch/arm/kernel/asm-offsets.c:20:0:
/home/androiddev/linus/linux/arch/arm/include/asm/glue-df.h:107:2: error: #error Unknown data abort handler type

回答1:

If you do

make menuconfig

then configuration is read for x86 not for ARM. First you need to take default configuartion look @ this

Are kernel headers depend on processor type, vendor etc?

also

hv look @ Just black screen after running Qemu

if you dont know the configuration you can get copy of .config from target rootfs /proc/config.gz

回答2:

For some reason ARCH is not a part of the saved configuration. As soon as you run any make command without the ARCH=arm it defaults back to PC architecture. Compiling a kernel configured for Intel with an arm compiler leads to problems.

I usually commit my own local ARCH=arm in the kernel top level makefile to avoid exactly this problem but I really don't understand why it is not a part of the saved configuration it would save a lot of headaches for people working on non-intel based architectures...
