Debugging Core Files Using HP WDB (5900-1573; WDB 6.2; January 2011)

Debugging a core file on a system other than the one on which it was originally produced

is supported only under the following condition:

The correct system and user shared libraries are copied with the executable and core

file to the other system, and the location of the shared libraries is defined by setting

GDB_SHLIB_PATH or GDB_SHLIB_ROOT before debugging the core file.

For more information about these variables, see the Debugging with GDB manual

available at:

Table 3 lists the supported systems for debugging PA-RISC core files.

Core files produced by Integrity systems can be debugged on any Integrity system with

an HP-UX version greater than or equal to the HP-UX version on the system where the

core file was produced.

Table 3 Supported Systems for PA-RISC Core File Debugging

Supported systems for debuggingType of core files produced

Any PA-RISC 1.1 or PA-RISC 2.0 system with an

HP-UX version greater than or equal to the HP-UX

version on the system where the core file was

produced.

Core files produced by 32–bit executables

Other PA-RISC 2.0 systems with HP-UX versions

greater than or equal to the HP-UX version on the

system where the core file was produced.

Core files produced by 64–bit executables

Table 4 lists the commands for debugging a core file from a different system.

Table 4 Commands for Debugging a Core File From a Different System

DescriptionCommand

Packs the core file along with the relevant executable

and libraries in a single .tar file.

packcore

Unpacks the .tar file generated by the packcore

command. The debugger can use the executable

and shared libraries from this bundle while

debugging the core file on a system, which is

different from the one on which the core file was

originally created.

unpackcore

Enables you to examine a packcore directory,

which was previously created by unpackcore. It

takes one optional argument, which is the name of

thepackcore directory.

getcore

To debug core files from a different system than the one on which the core file was

created, complete the following steps:
