Hi Daniel,

	You said I need the libraries available in the same path for both
host and target. But gdb can load ld.so.1 successfully , in fact my target
doesn't have the path  such as
/opt/montavista/pro/devkit/ppc/8xx/target/lib, ld.so.1 was storaged in  /lib
for  target. It means gdb load the same library use different path.
Why gdb can't load other library use different path. 
	BTW /mnt/cf/shared/lib was added in the ld.so.conf  for target. I
guess $(CROSS_COMPILE)/lib is the default library path for montavista, in
target,   $(CROSS_COMPILE) is a empty string, so for gdb both
/opt/montavista/pro/devkit/ppc/8xx/target/lib and /lib are equle to
$(CROSS_COMPILE)/lib. But when I use echo $CROSS_COMPILE in host,

Have a lot of fun...
metrodev:~ # echo $CROSS_COMPILE

metrodev:~ # 
It displays empty string
Could you give me directions.

Thx,
Xi

That means /mnt/cf/shared is the path on your target where these libraries
are found.  You need the libraries available in the same path (plus sysroot)
on your host that is used on your target.  Try running ldd on the target
instead of the cross ldd.
