Do you compile with cross compiler? Export ARCH and CROSS_COMPILE before
run make?

Hi Marek

Thanks for your help.

compiler = Sourcery G++
The path is ready added.

From my picture, it should able to run compiler(Sourcery G++) & access code
file. But compiler say 'SEGMENT_SIZE' undeclared (first use in
this function). Seem something necessary to define before compile.

From binfmt_aout.c(line 99) Seem to define "START_DATA". Which is relate to
line 317

***************************************
#if defined(__alpha__)
#       define START_DATA(u)  (u.start_data)
#elif defined(__arm__)
#  define START_DATA(u)  ((u.u_tsize << PAGE_SHIFT) + u.start_code)
#elif defined(__sparc__)
#       define START_DATA(u)    (u.u_tsize)
#elif defined(__i386__) || defined(__mc68000__) || defined(__arch_um__)
#       define START_DATA(u)  (u.u_tsize << PAGE_SHIFT)
#endif
#ifdef __sparc__
#       define START_STACK(u)   ((regs->u_regs[UREG_FP]) & ~(PAGE_SIZE -
1))
#else
#       define START_STACK(u)   (u.start_stack)
#endif

Hi, well try to compile this way: make ARCH=arm CROSS_COMPILE=<prefix to
your cross compiler (without gcc) e.g. arm-linux-

marek

right. 

initially in Makefile is 
"CROSS_COMPILE=arm-linux-"
then modify it to be
CROSS_COMPILE=arm-none-linux-???(I am not sure)

After that it can beginning to complie. 
But shop in 'SEGMENT_SIZE' undeclared

check if arm-none-linux-gcc is in your patch (which arm-none-linux-gcc
should give some path). Also ARCH=arm is set? Could you post sources what
you try to compile?

Thanks for your help.
Do you mean below?
****************************

export KBUILD_BUILDHOST := $(SUBARCH)
ARCH    ?= arm
#CROSS_COMPILE  ?= arm-linux-
CROSS_COMPILE  ?= arm-none-eabi-

For source issue, the whole set source file is very big.
or you mean "Makefile"? Which is attached.

For source, please download with below link.
http://www.friendlyarm.net/dl.php?file=android-kernel_20090825.tgz
http://www.friendlyarm.net/dl.php?file=android-fs_20090825.tgz

I find some info.

Who said something necessary be selected in make menuconfig to support
a.out.

Executable file formats ---> 
<M> Kernel support for a.out and ECOFF binaries 

What is the mean/ function of it"Kernel support for a.out and ECOFF
binaries"?

Also what different between "<M>" & "<*>"? Since the initial state is <*>.

Well your problem could be fixed:
1. rename in kernel directory config_mini2440 to .config
2. make ARCH=arm CROSS_COMPILE=arm-none-eabi- 

You will have no problems with compilation (at least I don't have ;)).
