Unix Core dump files: Debugging

Sanjay Verma — Thu, 05 Dec 2002 05:54:42 GMT

Hi Friends,

As I understand there are two popular tools for debugging the Unix core dump files - gdp & dbx. I am following questions:

(a) Is there any HP-UX proprietory debugging tool available?

(b) From where I can download these debuggers?

(c) Which one is the most efficient and debugs the best.

Regards,
Sanjay

Haven't heard of these debuggers you mention, but you can try using the GNU debugger (gdb) from here http://sources.redhat.com/gdb/download/
It works well on Unix, and its easy to backtrace core files to pinpoint the cause of the error.

Or you can try wdb, which has some additional features over gdb and is supported by HP. http://h21007.www2.hp.com/dspp/tech/tech_TechSoftwareDetailPage_IDX/1,1703,1672,00.html

Thanks Deepek. I've downloaded the copy but getting the following error mesg. when installing the too. Any idea about this?

# swinstall -s /opt/psoft/downloads/wdb-gui_1.4.01.depot \*

Hi

I agree with Deepak, "Gdb" is one of the best debugger for Unix. The binary for gdb-5.2.1 only for HPUX-11.00 can be downloaded from:

http://hpux.connect.org.uk/hppd/hpux/Gnu/gdb-5.2.1

If you want the graphic version you should take the ddd program.

In regard to your above question you need to type:

swinstall -s /opt/psoft/downloads/wdb-gui_1.4.01.depot wdb

Thanks

Hi Sanjay,

U might have downloaded an incompatible version and trying to install.(i.e you may be trying to install wdb for HP-UX 11.0 in HP-UX 10.20 box)

If U are still sure that U have the right version to install then, u may have to change some of the defaults to swinstall.

# swinstall /opt/psoft/downloads/wdb-gui_1.4.01.depot \* -x match_target=false

may be allow_incompatible=false

Check out the man page of swinstall and confirm both the above switches (match_target& allow_incompatible).

Sundar.

Hi Deepak, Mehdi & Sundara

Yes, you all are right. Basically the diff. version of wdb was downloaded. When downloaded the correct version - wdbgui-3.1.1-11.00.depot (approx 10MB), it worked fine.

Thanks for your brilliant suggestions.

Cheers,
Sanjay
