Hello again,
it seams that the compiler use an old version elf2flt. So I start to try
to compile the version from
http://cvs.uclinux.org/cgi-bin/cvsweb.cgi/elf2flt/. After downloading
the files I read the README.
Here is described that I need the libbfd.a and libiberty.a from the
toolchain. But Sourcery only
contains the libbfd.a. The other file is not in the directory-tree of
Sourcery. I found an alternative
in /usr/local/arm-linux/lib. But when I try to use it, I get some error
messages about relocations:
They all looks the same way:
------------------8<---------------------8<-----------------------8<---------
/usr/bin/ld: /usr/local/arm-linux/lib/libiberty.a(cplus-dem.o):
Relocations in generic ELF (EM: 40)
------------------>8--------------------->8----------------------->8---------
I also found them in /usr/local/arm-linux/be, ./soft-float and
../soft-float. But also this files generate
the same errors. So I think that this files are not the right one.
Is there a way to compile elf2flt for CodeSourcery arm-uclinuxeabi-?
Thanks and regards
Frank

Hello all,
I have find out that my kernel doesn't execute any elf-file. I got an
image with from a friend in bFLT format which run on my system.
So the kernel hasn't included any support for ELF, but every executable
image is compiled as ELF.
So I read a lot about bFLT and using arm-uclinuxeabi- compiler from
CodeSourcery seams to be the best choice instead of
arm-none-linux-gnueabi-, because it's also contains the elf2flt
executables. But when I try to compile the distribution I get the
following errors:
------------------8<---------------------8<-----------------------8<---------

------------------>8--------------------->8----------------------->8---------
When I understand this right, this relocations are ARM specific and not
supported by elf2flt. Is there any workaround or maybe a new version
available?
An other way is to activate the ELF support for the kernel, but I
couldn't find this switches in the config-files. Did someone know which
switches has
to set, that the kernel also support ELF-images?
Thanks and regards
Frank
