Hi,
I'm trying to debug my gcc compiled code on my HPUX 11.23 (Itanium).
I searched the machine to find something that looks like a compiler, and what I found was :
adb (a bit unfriendly for debugging)
kwdb (I understand this is a kernel debugger)
gdb32
gdb64
gdbpa
When I run either... (0 Replies)

crashinfo
CRASHINFO(8) BSD System Manager's Manual CRASHINFO(8)NAME
crashinfo -- analyze a core dump of the operating system
SYNOPSIS
crashinfo [-d crashdir] [-n dumpnr] [-k kernel] [core]
DESCRIPTION
The crashinfo utility analyzes a core dump saved by savecore(8). It generates a text file containing the analysis in the same directory as
the core dump. For a given core dump file named vmcore.XX the generated text file will be named core.txt.XX.
By default, crashinfo analyzes the most recent core dump in the core dump directory. A specific core dump may be specified via either the
core or dumpnr arguments. Once crashinfo has located a core dump, it analyzes the core dump to determine the exact version of the kernel
that generated the core. It then looks for a matching kernel file under each of the subdirectories in /boot. The location of the kernel
file can also be explicitly provided via the kernel argument.
Once crashinfo has located a core dump and kernel, it uses several utilities to analyze the core including dmesg(8), fstat(1), iostat(8),
ipcs(1), kgdb(1), netstat(1), nfsstat(1), ps(1), pstat(8), and vmstat(8).
The options are as follows:
-d crashdir
Specify an alternate core dump directory. The default crash dump directory is /var/crash.
-n dumpnr
Use the core dump saved in vmcore.dumpnr instead of the latest core in the core dump directory.
-k kernel
Specify an explicit kernel file.

The crashinfo utility appeared in FreeBSD 6.4.
