Analyzing core dumps

WSS — Wed, 03 Aug 2005 11:32:49 GMT

Hi there ... Can someone please tell me the best way to analyze core dumps in HPUX and the syntax required? The core dump file is called "core"

I have tried gdb but with no luck. Which is the best way? (please include explanation with syntax) ....

Thanks in advance.

Trevor,

you might want to look at the windows interface: wdb. This product also comes with gdb.
