Hi
I would like to use PBO optimization but I have several dynamic libraries and I can't set it successfully.
I did not find a clear document about the "how to"
Can somebody help me thru this issue?
Thank you

Re: HOW TO implement PBO when using .sl libs
from the hpux linker and libraries user's guide -
http://docs.hp.com/hpux/onlinedocs/B2355-90654/B2355-90654.html (or ld +help) :
To profile shared libraries, you must set the environment variable
SHLIB_FLOW_DATA to the file that receives profile data. Unlike FLOW_DATA,
SHLIB_FLOW_DATA has no default output file. If SHLIB_FLOW_DATA is not set,
profile data is not collected.

Re: HOW TO implement PBO when using .sl libs
thank you.
using your recommendation, I got my flow.data
It appears that for phase 3 of PBO it needs an explicit path for the flow.data so:
I forced the use of the flow.data with the +df otion like this:
/opt/aCC/bin/aCC +O2 +P -Wl,-aarchive_shared +df../flow.data -I/home/TANGO/STLport/stlport -D__unix__ -D__hpux__ -Wl,+s -Wl,+blib +z +Z -mt -AA -ext +DA2.0 +W829,921,652 -L./lib -L/home/TANGO/STLport/lib -L/usr/local/lib -b -o lib/libtg_disp.sl tmp/expatpp.o tmp/matchs_routages_parser.o tmp/regles_routages_parser.o tmp/routes_routages_parser.o tmp/tg_dispatcher.o tmp/tg_dispatcher_cfg.o tmp/tg_dispatcher_customer.o tmp/tg_dispatcher_log.o tmp/tg_dispatcher_request.o tmp/tg_dispatcher_routage.o tmp/tg_dispatcher_subscriber.o tmp/tg_dispatcher_timer.o
but I still get this message:
/usr/ccs/bin/fdp: No profile data for program lib/libtg_disp.sl in profile database ../flow.data
/usr/ccs/bin/ld: (Warning) Error executing feedback directed positioning call graph tool: /usr/ccs/bin/fdp
What went wrong?
