Code Profiling in 'C' programs by using gcc compiling suite

I'm trying to profile some C program code on HP-UX by using gcc via following command:

mygcc +DA1.1 -Wl,+s -D__BIGMSGQUEUE_ENABLED -I$TUXDIR/include -o ../../TMPBIN//TrafficArchiverE BS-5f07.c -L${TUXDIR}/lib ../../TMPOBJ//TrafficArchiverE.o -pg /dsk2/pri/h3gcallt/libcbin/LIB_DataBase.a /dsk2/pri/h3gcallt/libcbin/LIB_FileManager.a /dsk2/pri/h3gcallt/libcbin/LIB_Log.a /dsk2/pri/h3gcallt/libcbin/LIB_SHMManager.a /dsk2/pri/h3gcallt/libcbin/LIB_Expression.a /dsk2/pri/h3gcallt/libcbin/LIB_Timing.a /dsk2/pri/h3gcallt/libcbin/LIB_LicManager.a /dsk2/pri/h3gcallt/libcbin/LIB_InterProcComm.a -L/usr/local/ssl/lib -lcrypto -ltux -lbuft -L${ORACLE_HOME}/lib -lm -lc -lnsl -lclient8 -lclntsh -lsql8 -lcommon8 -lgeneric8 -lnls8 -lcore8 -lwtc8 -lfml -lfml32 -lengine -lpthread -lcl -lnsl

Code is not profiled, and the following error is reported by the command execution:

/usr/ccs/bin/ld: Can't open gcrt0.o
/usr/ccs/bin/ld: No such file or directory

Trying using -p instead of -pg the following errors are displyed:

/usr/ccs/bin/ld: Can't open mcrt0.o
/usr/ccs/bin/ld: No such file or directory

Does patch PHSS-26559 solve this problem totally or partially?

Could be the problem originated by incomplete/damaged installation of gcc/OS?

Thankyou

mcrt0.o, gcrt0.o etc are sym links from /usr/lib into /usr/ccs/lib

If you have the sym link in /usr/lib, but don't actually have the files in /usr/ccs/lib, then you will get the problem you describe.

Actual files do not exist there!
thank you

I don't have the file either, but I use gcc, not aCC. Maybe the files come with the HP-UX C/C++ compiler? Presumably you have to pay if you want them.
