This is not the correct list; try gdb@sources.redhat.com.

This problem means that yur compiler uses inter-compilation-unit
references.  CVS GDB still does not support this.  Try checking out the
drow_intercu-20040221-branch branch from CVS.

Thanks for your help. 
I try to check out the branch you siad below, and I followed
instruction:

cvs -d :pserver:anoncvs@sources.redhat.com:/cvs/src login
{enter "anoncvs" as the password}

But I got connection timed out. 
Is the password problem?

Thanks.

Lan

Pserver is currently working fine for me; you'll have to check with
your network administrator, probably.

Daniel:

I check out the branch you mention, and thanks god, it works for most
part. But there are weird thing, I cannot set breakpoint in some source
file, GDB will complain " No source file named *** " and suggest to make
a pending breakpoint on future shared library. And also there are some
files; I can only setup one breakpoint, even at same place, after setup
first breakpoint in such file, when I try to setup second, GDB said" No
line *** in file *** ". But it works ok in some other files, I can setup
as much as I want breakpoints. And I didn't found and strange things in
these three kind of files. 

I think it may be some miscommunication between armcc and GDB, they are
not compatible. Doi you have any idea? And I also want to ask people who
built drow_intercu-20040221-branch branch, but I don't know how. 

Thanks a lot. 

Regards,
Lan
