The libs are Vx Works libs and I'm using CodeSourcery
arm-none-elf legacy ABI variant.
Actually I posted the same question to the
CodeSourcery and I'v got an answer that claims that
the ABI is slightly different in Vx Works case.

How can I test if the REL / RELA issue ? What is
actually this issue about ? debug symbols ? if so, I
can get rid of them.

They are incompatible relocation formats; look at the objects with
readelf and you should be able to identify the format used.  The
CodeSourcery arm-none-elf compilers are not compatible with VxWorks.

You didn't mention what target you are using.  It sounds like one of
your toolchains is REL, and the other is RELA; that is a pretty big
incompatibility.

Binutils compatilibty

[George Haddad]

Hi All,

I'm trying to link a file generated by GCC 3.4.x using
binutils 2.15 with a library previously generated by
GCC 2.9X and binutils 2.9.

I get the following error message -
test.o: relocation size mismatch in libcortex.a .text
final link failed: Archive object file in wrong format

This is probably a compatibility issue; is there any
workaround for this issue ? Script ?

p.s. I don't have the sources for the library; so I
can't recompile with GCC 3.4.x and binutils 2.15.
