an error about "relocation truncated"

an error about "relocation truncated"

[lew kenny]

Hi,
I'm porting the PPCboot2.0 to my ppc850 board.I just modified the Makefile,
config file,and the flash's code and head file with the template of board
c2mon. But after I compile the code, there are some "relocation truncated"
errors.

At first, I think it may be caused by a low version number ompiler. Then I
changed the compiler to the last ELDK. But there are some new errors.

I doubt that there maybe are some ploblems in the "ppcboot.lds". I am not
sure of it, and I have no idea how to change it. It will be very
appreciated if anyone give me some ideas.

Thanks a lot,

PPCBoot is a dead project. Porting it to new boards  is  a  waste  of
time. Please use the successor project U-Boot instead.

Also, please  post  U-Boot  related  questions  to  the  u-boot-users
mailing list. They are off topic here.

No. The primary error is here:

You understand what "undefined reference" means?

Undefined references have little to do with the compiler version.

Instead of spreading wild speculations you should start  reading  the
documentation, especially this section in the FAQ:
