I am trying to build linux kernel 3.2.81 for ARM.
Here are the steps I am following:
- wget http://www.kernel.org/pub/linux/kernel/v3.0/linux-3.2.81.tar.gz
- tar xvzf linux-3.2.81.tar.gz
- export ARCH=arm
- export CROSS_COMPILE=arm-linux-gnueabi-
- cd linux-3.2.81
- make vexpress_defconfig
- make all
This is the error output I am facing, when I make step 7 (make all):
CC init/do_mounts_initrd.o
LD init/mounts.o
init/do_mounts_initrd.o: In function `return_address':
/home/ramy/QEMU_Learn/Kernel/linux-3.2.81/arch/arm/include/asm/ftrace.h:51: multiple definition of `return_address'

make[1]: *** [init/mounts.o] Error 1

make: *** [init] Error 2
This is the part in ftrace.h (ftrace.h:51) mentioned in the error:
#if defined(CONFIG_FRAME_POINTER) && !defined(CONFIG_ARM_UNWIND)
/*
* return_address uses walk_stackframe to do it's work. If both
* CONFIG_FRAME_POINTER=y and CONFIG_ARM_UNWIND=y walk_stackframe uses unwind
* information. For this to work in the function tracer many functions would
* have to be marked with __notrace. So for now just depend on
* !CONFIG_ARM_UNWIND.
*/
void *return_address(unsigned int);
#else
extern inline void *return_address(unsigned int level)
{
return NULL;
}
I am working on Ubuntu operating system, and using Linaro tool chain.
