Fwd: Crosscompilation for ARM fails (C compiler cannot create executables error)

[Francisco Cuesta <ndarkness at gmail dot com>]

Hello,

I am trying to cross-compile gdbserver 7.5 (not 7.6 since I was trying
to compile directly from scratch for my x86 and I got an pointer
casting error which aborted its compilation)for my target whose
architecture is ARM.

I have read the document
https://sourceware.org/gdb/wiki/BuildingCrossGDBandGDBserver ,  and I
have come across with the following script which fires the
crosscompilation options

#part for compiling just gdbserver
mkdir buil-gdbserver/
cd buil-gdbserver/
export CC="/home/j/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-gcc"
export CXX="/home/j/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-g++"
export AR="/home/j/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-ar"
CONFOPTS+="--target=arm-linux --host=arm-linux --build=i686-pc-linux-gnu "
~/gdb-7.5/configure ${CONFOPTS}

However when I run the script with make, I got

ubuntu:~/gdb-7.5/build-gdbserver$ ./gdbCompiler.sh
mkdir: cannot create directory `buil-gdbserver/': File exists

configure: error: in `/home/j/gdb-7.5/build-gdbserver/buil-gdbserver':
configure: error: C compiler cannot create executables
See `config.log' for more details.

Looking into the config.log,below, I can read in the highlight text
the fact that it isn't pointing at the correct gcc cros-compiler, but
I cannot understand why, if the path is the proper one...

What may it be happening?

Thanks in advance,

BEst regards

It was created by configure, which was
generated by GNU Autoconf 2.64.  Invocation command line was
