14.35.1 Support for command line calls in a stripped executable on PA-RISC systems

In WDB, to perform command line calls in a shared library without the help of dynamic linker (using end.o), you must execute the following command:

chatr -B immediate <executable>

In addition, modify all the calls to shl_load() to specify BIND_IMMEDIATE.

To perform command line calls after attaching a running process to GDB, you must execute one of the following commands:

•/opt/langtools/bin/pxdb -s on <executable>

•chatr +dbg enable <executable>

14.35.2Additional support for command line calls in a stripped executable

HP WDB enables you to perform command line calls in a stripped executable. The various scenarios in which you can make command line calls in a stripped executable are as follows:

14.35.2.1 For 32-bit applications:

To perform command line calls in a shared library, without the help of dynamic linker (using end.o), you must perform the following operations:

•Execute the chatr -B immediate <executable> command.

•Modify all the calls to shl_load() to specify BIND_IMMEDIATE, if any.

To perform command line calls after attaching GDB to a running process, without the help of dynamic linker (using end.o), you must do the following for the program:

•Execute the chatr -B immediate <executable> command

•Modify all the calls to shl_load() to specify BIND_IMMEDIATE, if any.

•Execute the /opt/langtools/bin/pxdb -s on <executable> or chatr +dbg enable <executable> command.

On HP-UX 11i v3 Integrity systems, WDB enables automatic debugging of shared libraries without them being mapped private while attaching to a running program. For enabling automatic debugging of shared libraries, you must install the kernel patches PHKL_38651 and PHKL_38778.

To avoid changing of the run-time binding behavior of a program to BIND_IMMEDIATE, to perform command line call, do the following:

•Use the linker option, +ea, to export symbols from an object file.

•Install the linker patch, PHSS 28870 (for 11.0) or PHSS 28871 (for 11i).

•Execute the following commands:

cc -c file.c cc file.o -Wl,+ea,/opt/langtools/lib/end.o -s
