I'll corss-compile gdb for arm board, will use gdb to debug on arm board.
I use gdb6.0 or gdb6.3 and configure with:
CC=arm-linux-gcc ../gdb-6.3/configure --target=arm-linux \
--build=arm-linux --host=arm-linux

and has error when make:
checking whether make sets $(MAKE)... (cached) yes
checking for arm-linux-gcc ...(cached) arm-linux-gcc
checking for c Compiler default output in a.out
checking whether the c compiler makes in
configure:error: cannot run c compiled programs

if you meant to cross compile usr "--host"
see 'config.log' for more details

I don't know how to do with it ,something wrong?

hi,

You may refer to the following post, which has a build script.

http://gcc.gnu.org/ml/gcc/2003-10/msg01339.html

Thanks,
Neo

I would remember that if researchers were not ambitions
probably today we haven't the technology we are using!

What kind of machine are you compiling GDB itself on?  That should be
your --build.

What kind of machine do you intend to run GDB on while you debug your
ARM programs?  That should be your --host.

Will you run GDB on the same machine as the program being debugged? 
Then your --host and --target should be the same.  If you're going to
run GDB on a different kind of machine (and debug over the network, or
over a serial line), then your --host and --target should be
different.

Yes Thanks, I modified the --build to my x86 and --host to arm-linux,
and set bash_cv_have_mbstate_t to yes, now to compiles ok, I can debug on 
arm platform!
