Help rtcconfig

Harshit Maurya — Wed, 08 Jun 2011 11:59:17 GMT

On HP-UX B.11.31 U ia64 we are trying to generate .mem and .leaks files using gdb, but not files are getting generated on proper exit of application.

$ cat rtcconfig
set heap-check on
set heap-check leaks on
set heap-check free on
set heap-check string on
set heap-check bounds on
files=/opt/xyz/server/xyzSTET
output_dir=/tmp

Environment variables
BATCH_RTC=on
GDBRTC_CONFIG=/opt/xyz/server/rtcconfig
LD_PRELOAD=/opt/langtools/lib/hpux64/librtc.so
RTC_NO_ABORT=1
GDB_SERVER=/opt/langtools/bin/gdb

Am I missing something because no files are getting generated.
Let me know if I have to provide more info.

Thanks.

Hi:

Perhaps a quick read of this would help:

http://h21007.www2.hp.com/portal/download/files/unprot/wdb/wdb_6.2/memdebug-updated.pdf

In particular, see the Prerequisites section on page-7.

"WDB uses the heap debugging library, librtc.[sl|so], to enable memory-debugging support. The librtc.[sl|so] library is a part of the HP WDB product. If the debugger is installed in a directory other than the default /opt/langtools/bin directory, you must use the environment variable, LIBRTC_SERVER, to set the path of the appropriate version of librtc.[sl|so]."

Regards!

Thanks James, I found the documents very useful indeed.

I crosschecked the prerequisities and they all looks fine to me.
I set LIBRTC_SERVER and GDB_SERVER, though these were installed on standard paths.

Could you think of any other input which will help me generating the reports.

Thanks.

How is the process exiting?

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

And you do have a 64 bit process?

How is the process exiting?
-- With a return from main.

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

And you do have a 64 bit process?
-- ELF-64 executable object file

I did a fuser for the shared lib and the rtcconfig file and both are attached to the process.

Thanks for help.

What version of WDB do you have?

That's pretty convincing.

What version of WDB do you have?

$ /opt/langtools/bin/gdb -version
HP gdb 5.9 for HP Itanium (32 or 64 bit) and target HP-UX 11.2x.

Thanks.

You might try downloading the latest, 6.2.
