Hi John,
   Thanks for your mail. I included the package "CYGPKG_MEMALLOC". After I
compile the ECOS , I am not able to find the malloc.h file. Instead of
malloc.h file, in the ECOS install directory I found memalloc.h file.

Do I need to include some other packages?  

Thank you,
S.Ramesh Chandra.

It sounds like the C pre-processor is finding a version of malloc.h in
the arm-elf toolchain when you compile your application code rather than
the version provided by the eCos package CYGPKG_MEMALLOC.

Make sure that you are using the correct compiler flags to compile your
application code. Typically, these should match the flags used by the
eCos build system when compiling eCos tests.

I hope this helps...
