Hi,all :)

  I'm just beginning to port gdb to a new target.I've modified some
configuring files and added several files such as cpu-*.c,elf32-*.c,*-tdep.c
to support my new chip(of couse,I only changed the names of other machine's
files). Now I can use command of "configure" to configure gdb as my  target
correctly.But when I try to make it there is alway an error that I can't get
rid of.

I do add this line to file of bfd/targets.c:
**extern const bfd_target bfd_elf32_vp6_vec;**

  I'm totally a beginner not only of gdb but also of programming. Any
response will be appreciated very much and thanks in advance.:)

This looks like more of a BINUTILS (binutils@sources.redhat.com) 
question.  Can you, for instance, get OBJDUMP to build?

GDB and BINUTILS share a common repository and much code so it is 
possible to CO either or both together.  See: 
http://sources.redhat.com/binutils/.  Also see: 
http://sources.redhat.com/gdb/current/ (use gdb+binutils).

I'm so grateful for your response and sorry to bother you again.
Do you mean that GDB needs BINUTILS's support? So if I want to port gdb ,I
should make some changes to BINUTILS  first?Is there some other special
support gdb requires? And how can I get OBJDUMP? What kind of file is it? 

best of luck
