Here is the makefile I use:
$(TARGET): $(SOURCE) $(SOURCE:.pc=.c) $(SOURCE:.pc=.o)
$(CC) $(LDFLAGS) -t -o $(TARGET) \
$(SOURCE:.pc=.o) $(PROLDLIBS)
include $(ORACLE_HOME)/proc/demo/proc.mk
PROFLAGS= ireclen=255 lines=yes $(PROC_ENV_FLAGS) \
include=$(ORACLE_HOME)/proc/lib CFLAGS=-I. -g $(CC_ENV_FLAGS)
You set the TARGET and SOURCE fields in the makefile and it does the rest. Precompiles/compiles and links pro*c. The trick is to include the standard oracle makefile (ignore it's trickyness alltogether, it is a makefile that can build everything/anything on quite a few platforms. This tends to make it not so readable).
I use the following shell script to build my programs. It assumes that you are in a subdirectory, the subdirectory is named after the program you want to build (eg: /home/tkyte/src/program1 would assume a TARGET of program1). It also assumes that the current directory is full of .pc files you want compiled/precompiled/linked together to build that program. I have used this on many UNIX systems unchanged.
NOTE: the above makefile needs to change for 7.3. The include will include $ORACLE_HOME/precomp/demo/proc/proc.mk as they moved the makefile.
SRC=`echo *.pc`
TGT=`pwd | sed 's".*/""'`
echo SRC = $SRC
echo TGT = $TGT
echo Remember you can set PROC_ENV_FLAGS to pass things to ProC
echo Remember you can set CC_ENV_FLAGS to pass things to CC
make -f /export/home/tkyte/bin/proc.mk "SOURCE=$SRC" "TARGET=$TGT"
