GNAT/RTEMS instalation: problems runing bit_ada script

[Sergio]

I'm trying to install GNAT/RTEMS on Linux with i386 as target.
When I run the bit_ada script I get the following error:

gcc -c -O2 -I. -I../../src/libiberty/../include
../../src/libiberty/cplus-dem.c
../../src/libiberty/cplus-dem.c:35:22: demangle.h: No such file or directory
gmake[1]: *** [cplus-dem.o] Error 1
gmake[1]: Leaving directory
`/root/rtems/build/ada/build-i386-tools/libiberty'
gmake: *** [all-libiberty] Error 2


I found that gcc can not reach paths like "../../src/libiberty/../include"
where "../../src/libiberty/" is a link made by the "make_one_tree" routine
(file "common.sh").


If I copy the files instead of creating links, I get the error:

/bin/sh ../../src/libiberty/../move-if-change config.tmp config.h
touch stamp-config
gmake[1]: *** No rule to make target
`../../src/libiberty/../include/libiberty.h', needed by `argv.o'.  Stop.
gmake[1]: Leaving directory
`/root/rtems/build/ada/build-i386-tools/libiberty'
gmake: *** [all-libiberty] Error 2


Then I tried to copy the .h files needed to the directories searched, but it
also don't work:

gcc -DHAVE_CONFIG_H -I. -I../../src/bfd -I. -D_GNU_SOURCE -I. -I../../src/bf
d - I../../src/bfd/../include -O2 -c ../../src/bfd/reloc.c
 ../../src/bfd/reloc.c: In function
`bfd_generic_get_relocated_section_contents':
../../src/bfd/reloc.c:2587: too few arguments to function
 gmake[1]: *** [reloc.lo] Error 1


Someone tried to install GNAT/RTEMS on Linux?
What files must really be in the "src" directory?
What I'm missing? I already read the "Getting Started with GNAT/RTEMS" doc.

Any comment is welcome.

Thanks
