Re: Unable to use objcopy on AIX

I want to use gdb to do that.. In gdb we can load release version of
executable's symbol file using symbol-file <symbol file path>. when we do
that, the debug information is gets attached in the debugging session and we
can see all debug information like line numbers, functions names as we see
with a debug binary.

When I saw man page of AIXs's strip command i see some statements like..

"Once you use this command, symbolic debugging of the file is difficult;
therefore, you should normally use the strip command only on production
modules that you have debugged and tested." By this what i understood is
strip doesn't allow the stripped symbols cannot be stored in another file.

same man page also says below stuff.
"You can restore a stripped symbol table to an archive or library file by
using the ar -s command." 

I little bit confused by above two statements.. Can anyone clarify what the
second statement does really mean by "you can restore a stripped symbol
table to an archive or ..."

Also, I saw the binutils patch at
http://ftp.gnu.org/gnu/binutils/binutils-2.20-2.20.1-patch.gz. I tried to
build the binutils after installing the patch but when i was building the
binutils after installing above patch i am seeing compilation errors.
