RE: [arm-gnu] Core File seems to be corrupted

["Balaji Kani -X (balkani - WIPRO at Cisco)" <balkani@xxxxxxxxx>]

Hi Daniel,

   I downloaded the following tar files of "Sourcery G++ Lite 2009q3-67
for ARM GNU/Linux"
Source TAR
IA32 GNU/Linux TAR  
IA32 GNU/Linux Installer

URL: http://www.codesourcery.com/sgpp/lite/arm/portal/release1039

   Unfortunately, when I tried to untar/ungzip using WinZip I get the
following error:-
   "Error reading header after processing 0 entries"

 You mean GDB manual not supported ? or solib-absolute-prefix variable
not supported ?

 Thanks a lot for your help

Regards, Balaji

Please look at the GDB manual, which describes what the argument to
this command should be.

Sourcery G++ Lite is not supported; if you continue to have difficulty
configuring Linux debugging, you may want to consider an evaluation of
our Standard Edition or Professional Edition product for access to
support.

No modern compiler uses this frame layout.  If you upgrade to the
latest Sourcery G++ release, you can use the libc backtrace()
function, but it's never as reliable as GDB.
