Hello Anish
Thanks a lot dear for your helping hands.
It was delayed because i got stuck with my another project, so i left this LTP stuff for a while.
> 8. export PATH=/usr/local/arm/bin/:$PATH
> 9. export CC=/usr/local/arm/bin/arm-XXX-gcc
basically i downloaded the LTIB from Freescale and it has the toolchain so i try to use via that only.
i followed the steps same as you guided.
i set the above PATH and CC as
export PATH=/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/:$PATH
export CC=/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-gcc
and tried to $make
and it landed to an make error as: :S
make[4]: Leaving directory `/home/ydcd011/imx31ADS/ltp/ltp-full-20090831/testcases/kernel/syscalls/sighold'

> Summary:
> Resolve one final corner case required for make 3.80 compatibility to
> be complete (../.. -> $PWD/../..):
> 1. Add two additional testcases for the above corner case.
> 2. Fix expected output for ./.foo:/.foo and ./.foo/.bar:/.foo/.bar
> testcases; each of the expected results should have been correct from
> $PWD, as the input path was relative from $PWD.
> 2. Revise the library to use sub instead of gsub because it's being
> called from a loop already.
> 3. Reorder steps to correct for corner case. and document
>
> I'm confident that this is 100% ok for commit now after my subsequent
> testing and careful inspection. Committing this will enable 3.80
> compilation in mainline after I uncomment the $(error ) in env_pre.mk.
