HP gnu source-level debugger 5992-4701 For 32 bit IPF applications, For 64 bit IPF applications

4.Complete one of the following steps to preload the librtc runtime library:

•Set the target application to preload librtc by using the +rtc option for the chatr command. In addition to automatically loading the librtc library, the +rtc option for the chatr command also maps the shared libraries as private. To enable or disable the target application to preload the librtc runtime library, enter the following command at the HP-UX prompt:

$ chatr +rtc <enabledisable> <executable>

NOTE: The chatr +rtc option preloads the librtc runtime library from the following default paths:

–For 32 bit IPF applications,

/opt/langtools/lib/hpux32/librtc.so

–For 64 bit IPF applications,

/opt/langtools/lib/hpux64/librtc.so

–For 32 bit PA applications, opt/langtools/lib/librtc.sl

–For 64 bit PA applications,

/opt/langtools/lib/pa20_64/librtc.sl

To preload the librtc runtime library from a path that is different from the default paths, you must use the LD_PRELOAD environment variable.

•Instead of automatically preloading librtc and mapping the shared libraries, you can explicitly preload the required librtc library after mapping the shared libraries private.

In the case of HP 9000 systems, you must explicitly map the share libraries as private by using the +dbg enable option for the chatr command, as follows:

$ chatr +dbg enable ./<executable>

(This step is not required on Integrity systems.)

To explicitly preload the librtc runtime library and start the target application, enter one of the following commands:

– For 32-bit IPF applications,

LD_PRELOAD=/opt/langtools/lib/hpux32/librtc.so <executable>

– For 64-bit IPF applications,

LD_PRELOAD=/opt/langtools/lib/hpux64/librtc.so <executable>

– For 32-bit PA applications,
