Relocation errors

Relocation errors

[David Kesselring]

I'm getting the error "Unhandled relocation of type xx" on insmod. Are the
"types" documented somewhere? I am I correct that these "types" are
architecture specific?

Yes.  Try an ELF specification - there's a MIPS processor supplement
(psABI) floating around.  What's the "xx"?

It is type 8. Any ideas? This is from an intel driver that I've cross
compiled for mips. I used these options;
-mcpu=r4600 -mips2 -mno-abicalls -fno-pic -mlong-calls -Wa,--trap -DMODULE
-pipe -O3 -fomit-frame-pointer -fno-strict-aliasing

Thanks, David

Take a look at /usr/include/elf.h:
#define R_MIPS_LITERAL          8       /* 16 bit literal entry */

In this case it's not very informative.  But the problem is probably
mismatched CFLAGS.  Take another look at the options the kernel is
built with - you lost -G 0.  See if that does it.

My gcc patches used to set this to zero because the -G optimization doesn't
work on Linux; I think HJ Lu's (?) gcc patches lost this.
