The Error lies here. Do you have 'strip' from the Cross-Architecture
Binary Utils package. Apart from your GCC (which is from your GCC
package), all the following packages should also be from your CROSS
COMPILE ARCH:

Glibc
Glibc-devel
Binutils

If you see your 'strip' binary, probably it is still belonging to the
machine arch on which you are compiling.

# which strip
/usr/bin/strip

# rpm -qf /usr/bin/strip
binutils-2.20.51.0.2-5.27.el6.ppc64

Check that out first.

Re: [LTP] Cross Compiling LTP for Android platform

[G Rajender]

Hi,

Thank you for your reply and support.

I have checked for the strip with commands suggested by you.
# which strip
/usr/bin/strip

# rpm -qf /usr/bin/strip
"file /usr/bin/strip is not owned by any package"

I think strip not owned by any package....

How to modify or configure my arm-linux-androideabi- strip binutils.

Any suggestions please......

Thanks
Rajender.G

Install the Cross Compile Binutils of the target Arch in this machine.
Or, you can build the Target Arch Binutils in the source machine
provided you have the Binuitls source code.

So just like your 'arm-linux-androideabi-gcc' which shows up in
your /usr/bin/arm-linux-androideabi-gcc,

You will then have all the binaries of the Binutils package here:
/usr/bin/arm-linux-androideabi-stripe
/usr/bin/arm-linux-androideabi-ar
/usr/bin/arm-linux-androideabi-as
/usr/bin/arm-linux-androideabi-ld
/usr/bin/arm-linux-androideabi-nm
/usr/bin/arm-linux-androideabi-objdump

etc.

If you look into Makefiles (for example testcases/kernel/Makefile) there
often is check ifeq($(UCLINUX), 1) or something like that and some
tests/subdirectories are filtered out from the targets based on that. So
if you are using original LTP buildsystem you may just do the same for
android (and if done right, this changes will be accepted upstream).
