RE: cross targeted gdb and corefiles

["Kevin \"Squail\" Endres" <kevine at wildseed dot com>]

Yep - shot the last mail off before thinking it all through (sorries!!) -
Thanks for the help! (Got it all working!!)

TO RECAP: 
My environment - i386 host - ARM target (both running linux)

goal - read target core files with cross targeted debugger in host
environment.

SOLUTION:
1) configure cross gdb
2) add corelow.o and core-regset.o to TDEPFILES in gdb's Makefile
3) copy supply_* and nwfpe* functions and relevant structures (F11A etc)
from arm-linux-nat.c to arm-linux-tdep.c
4) remove system headers from arm-linux-tdep.c and core-regset.h (so not
using system register defs in gregset.h)
5) edit gregset.h - add the following (at the top): (i just copied and
synthisized from appt headers)

typedef  unsigned long elf_greg_t;
typedef  elf_greg_t gregset[18];
typedef struct {void *null } fpregset_t;

6) make

After getting environment set up same as required for remote debugging.

7) gdb app
8) (gdb) set solib-absolute-prefix /targetloc
9) (gdb) target core core

and all works as expected!!!

Help is much appreciated - you guys rule!

Can't you do...

    (gdb) set solib-absolute-prefix /my/prefix/to/the/sys-root
    (gdb) target core core

?
