Sorry about the confusion.  esh is a combination of several libraries.  I created an example rtems application that invokes esh at startup.  You can find it in the directory hello_world.  Note that the makefile in that directory will first create a symbol table from the object files, then link the RTEMS kernel with the sample app.

Thank you, I run size on this and then i386-rtems-strip. Size is much
smaller now:-)

But What With the info/warning message during rtems building time:
ELF type"0" not known.
It was about 20 such messages.
Test apps work well ( but I did not run all ones).
I instaled tools and rtems release 4.5.0. Tools of coures from this relese.

I dont know in which moments this messages occured because I build rtems with command (under bash):
bit_rtems i386 pc386 >& my_log_file
All messages went to my_..file
but this messages concerning to ELF 
was displayed only on my terminal.
