Trouble compiling gdb for host=i686 target=mips

[Curtis Veit <curtisv at lineo dot com>]

Hello,

I am going to be doing a bit of work in the near future with gdb (remote
debug for
various targets.  mips, ppc, sh, and arm) so I hope  in future I might
actually do
something helpful, for today though I'm afraid  that this is mainly a
request for help.
I've been trying to figure this out for a couple days now and find I am
lost!

I seem to be having trouble compiling gdb-5.0 configured for
--host=i686-pc-linux-gnu
and
--target=mipsel-elf-linux

I am running on an AMD K7 box.

I am using stock gdb-5.0 with the mips patches by Maciej W. Rozycki from

the gdb-patches mailing list.
(also available from  'http://www.ds2.pg.gda.pl/~macro/gdb-5.0/'.)

I am running OpenLinux 2.3 with some updates and gcc is version
egcs-2.91.66 19990314 (egcs-1.1.2 release)

My goal is to be able to remote debug an MIPS based development board
from IDT.
With both gdbserver and gdbstubs.

I did:
  ./configure --target=mipsel-elf-linux
  make

And got the following errors:

 gcc -DHAVE_CONFIG_H -I. -I. -I. -D_GNU_SOURCE -I. -I. -I./../include
-I./../intl -I../intl -W -Wall -g -O2 -c stab-syms.c -o stab-syms.o

I couldn't see anything wrong with the code in elf32-mips.c
(I guess I could have missed something here.)

Looking around for these declarations I find (in reloc.c)

 ENUM
   BFD_RELOC_MIPS_LITERAL
 ENUMDOC
   Relocation against a MIPS literal section.

 COMMENT
 ENUMDOC

I have not yet figured out where ENUM, ENUMX, and friends are provided
or what they mean (although I can guess, I can't see the code) my greps
have
not provided any real insight. I'm feeling rather blind...

Does anyone know what is going on or where I should look?
