[arm-gnu] arm-uclinuxeabi-elf2flt errors

[Frank Mölendörp <frank.moelendoerp@xxxxxxxxxx>]

Hi all,

I'm using CodeSourcery arm-uclinuxeabi 2010q1 version 4.4.1 to compile 
uClinux for
a ARM Cortex M4. The kernel itself run fine. But when the linker tries 
to make a flat-image
from an elf-file I get a couple of errors like this:
Trying libraries: crypt m
Failed: -Wl,--start-group -lcrypt -lm -Wl,--end-group
Output of:

/hom.../arm-uclinuxeabi/bin/elf2flt: error: 247 bad relocs


The problem is relative clear: The arm-uclinuxeabi-elf2flt don't 
understand the reloc's which are
generated. So I downloaded the source for elf2flt from 
http://cvs.uclinux.org/cgi-bin/cvsweb.cgi/elf2flt
and tried to compile them. But without success, the library 
(libiberty.a) needed to compile it is
not in the toolchain. The second one was in the directory 
.../arm-uclinuxeabi/lib/lib/libbfd.a.

So is there any idea where to get the missing file? Or howto get in an 
other way an elf2flt, which
can handle these reloc types?

thanks and regards

Frank
