[U-Boot-Users] -mrelocatable

[Forslin, Eric]

Hello,

I'm currently upgrading a custom PPCBoot 1.1.5 port to U-Boot 1.0.0 for a
custom 405GP-based board.  At the same time, I thought it would be a good
idea to upgrade my development system to SuSE 9.0 and tool chain to ELDK
3.0.

When I build U-Boot I get the following error when zlib.c is being compiled:

ppc_4xx-gcc -g  -Os   -mrelocatable -ffixed-r14 -meabi -D__KERNEL__
-DTEXT_BASE=

After doing a couple of quick Google searches, it appears that there might
be some sort of bug in GCC.  Does anyone know what the solution to this
problem is?

I can build without the -mrelocatable flag.  The board boots up but when
it's time to run from RAM it crashes, probably because the resulting code is
not relocatable.

Thanks for you help.

Eric
