Thank you for your answer
This is the output of my toolchain

As you can see gcc4.1.1.

I would be happy to use ecos tested toolchain but it seems that the link
(ftp://ftp.sourceware.org/pub/ecos/gnutools/cygwin/ecoscentric-gnutools-arm-
elf-1.4-2.cygwin.tar.bz2) provided does not work.
Thank you Adi Baron.

ecos-discuss@ecos.sourceware.org is the correct address.

Which toolchain are you using? What is the output of the following commands?

  arm-elf-gcc -v
  arm-elf-gcc -print-multi-lib
  arm-elf-ld -v

I suggest that you start experimenting with the eCos on the "aeb" target
using the eCos arm-elf toolchain:

lf-1.4-2.cygwin.tar.bz2
