But you do need to satisfy the reference. This would all be sorted out for you if you used the sun suppiled cc. However, for the benifit of us gcc users, Oracle ship an object file which will do. It is $ORACLE_HOME/lib/__fstd.o

The 7.1.4 version of proc.mk includes this file in the link. I havn't got a 7.1.3 version to look at. Relevant lines in the 7.1.4 file are:

CC=cc  

CFLAGS=
COMPOBJ=$(ORACLE_HOME)/lib
COMPOBJS=$(COMPOBJ)/crti.o $(COMPOBJ)/crt1.o $(COMPOBJ)/__fstd.o LDSTRING= -Y P,$(LD_LIBRARY_PATH):/usr/ccs/lib:/usr/lib -Qy -lc $(COMPOBJ)/crtn.o CC= ld -dy $(COMPOBJS)
ASFLAGS=-P
RCC=cc -I. -O -xcg92 Received on Fri Jun 23 1995 - 00:00:00 CEST
