I've built arm-elf-gdb on linux from the repository, and I encountered no 
problems.

Is libangsd.a being built and linked into gdb? (libangsd.a lives in 
rdi-share)

I'm doing a cygwin build now, and I'll post my results in a few hours.

I had no problems building on Win2000.

What does "head config.status" output?

I just retrieved this snapshot and built it on both windows and linux 
without any problems...

Is libangsd.a being built? Does the directory OBJDIR/gdb/rdi-share exist 
and contain anything? What do the last few lines of your final link look 
like? Mine look like:

Keith:thank you very much

(1) Yes!libangsd.a exists.And  There are some .o in my build library
(xxx/gdb/rdi-share)

(2) But I can't find any information about libangsd.a in my "make.out"

(3) uname -a say=>CYGWIN_98-4.10 CLIFF 1.1.8(0.34/3/2) 2001-01-03 10:58 i586
unknown.
      Do I need a newer version of cygwin? But I encounter another problem
after install newer version of
      cygwin when build insight!

By the way!I wanna know  can I build the insight for arm-elf that set
big_endian as default?
I've seen few lines in \gdb\config\arm\tm-arm.h about endian.
How can I do to set arm-elf take big_endian as default?
Or Where can I set in order for insight(build for little-endian as default)
to accept big_endian elf-image.

/*tm-arm.h*/
/* Target byte order on ARM defaults to selectable, and defaults to
   little endian.  */
#define TARGET_BYTE_ORDER_SELECTABLE_P 1
#define TARGET_BYTE_ORDER_DEFAULT LITTLE_ENDIAN

/* IEEE format floating point.  */
#define IEEE_FLOAT (1)
#define TARGET_DOUBLE_FORMAT  (target_byte_order == BIG_ENDIAN \
          ? &floatformat_ieee_double_big  \
          : &floatformat_ieee_double_littlebyte_bigword)
 .....


Thank you.

You must have something wrong with your build environment. I just 
downloaded (again) the insight+dejagnu-weekly-20010424.tar.bz2 snapshot 
from sources and built it on this system:

$ uname -a
CYGWIN_98-4.10 ANYWHERE 1.1.8(0.34/3/2) 2001-01-31 i586 unknown
$ gcc -v
Reading specs from /usr/lib/gcc-lib/i686-pc-cygwin/2.95.2-6/specs
gcc version 2.95.2-6 19991024 (cygwin experimental)

I installed it, too. Ran as expected. Something is really, really wrong 
with your setup.

You don't need to do anything. Gdb will automatically switch to 
big-endian if your executable is big-endian:

(gdb) show endian
The target endianness is set automatically (currently little endian)

> How can I do to set arm-elf take big_endian as default?

All you need to do is make arm-elf-gcc output big-endian code.
