Guys,
The error is in the sunject line. But, I found the problem: I missed
specifying the program name itself. I added that at end, and it
worked.

Following line worked (see the wsi_mgr.c at end) :

cc -Ae -D_HPUX_SOURCE -Wl,-adefault -Wl,+s -y
-o /apps/primary/wsi/src/bin/wsi_mgr
-L/opt/oracle_8.05/precomp/lib/
-L/opt/oracle_8.05/lib/ -I/opt/oracle_8.05/precomp/public
wsi_mgr.c


But now I am getting the following when it tries to link everything
into
an executable.


cc -Ae -v -Wl,-adefault -Wl,+s +O2

The way I have setup the Makefile is that it first compiles my
wsi_mgr.pc
file into a wsi_mgr.c, then compile the .c into a .o and finally link
all libraries with the .o into an executable wsi_mgr (no extension).

The wsi_mgr.pc looks like this:

<BOF>

/* Includes */
#include <stdio.h>
#include <stdarg.h>
#include <varargs.h>
#include <stdlib.h>
#include <errno.h>
#include <signal.h>
#include <string.h>
#include <memory.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <sys/socket.h>
#include <sys/stdsyms.h>
#include <dirent.h>
#include <time.h>
#include "../inc/wsi_mgr.h"
#include "../inc/constants.h"
#include "../inc/scale.h"

/* Global Variables */
#ifndef DEBUG
#define DEBUG
#ifdef EXTERN
extern int Debug_level;
#else
int Debug_level;
#endif
#endif

void main (argc, argv)
int argc;
char *argv[];
{
char *st;
int cc;


init_global_vars();

if (argc >= 2) /* first argument is
debug level */
Debug_level = atoi(argv[1]);
else
Debug_level = 0;

sprintf(Log_Msg,"Debug Level=%d",Debug_level);
Log_Message(Main_Log, "main", INFORM, Log_Msg);

/* Trap System Signals
*/
signal( SIGKILL, Terminate ); /* Signal Kill
*/

/* Run the Scale Main
*/
/* THAT process is
going to run infinitely */
if (atoi(getenv("TEST"))==0)
{
Log_Message(Main_Log, "main", INFORM, "Started
Production version");
cc=scale_main();
}
else
{
Log_Message(Main_Log, "main", INFORM, "Started Test
version");
t_scale_main();
};

/* Terminate normally
*/
if (cc==0)
Log_Message(Main_Log, "main", FATAL, "WSI Process Ending
Normally...");
else
Log_Message(Main_Log, "main", FATAL, "WSI Process Ended
Abnormally...");

} /* End of Main */
/* here follow the functions init_global_vars(), and Terminate() */

<EOF>


The functions scale_main(), t_scale_main(), and Log_Message()are
defined
in wsi_mgr.a and std_lib.a libraries.

Please help.
Thanks so far.

You need to read a decent handbook on compiling on Unix. The short
answer is: put the libraries in the correct order _after_ all
object/source files on your compilation commandline.

I do not understand the above command. Why are there two -o options?

Regardless, the order is incorrect. On many platforms, the load is not
circular until all externals are satisfied, so if code in wsi_mgr.o
refers to functions in the wsi_lib.a, you have to place the library
reference after the .o:

ld -o /apps/primary/wsi/src/bin/wsi_mgr
wsi_mgr.o
/apps/primary/wsi/src/obj/wsi_lib.a
/apps/primary/wsi/src/obj/std_lib.a
...

If you named your libraries "libwsi.a" and "libstd.a", you could use cc
like this:
cc -o /apps/primary/wsi/src/bin/wsi_mgr ....
wsi_mgr.o -L/apps/primary/wsi/src/obj -lwsi -lstd ...

cc -Ae -c wsi_mgr.c -o /apps/primary/wsi/src/obj/wsi_mgr.o
cc -Ae -o /apps/primary/wsi/src/bin/wsi_mgr \
/apps/primary/wsi/src/obj/wsi_mgr.o \

/usr/ccs/bin/ld: Unsatisfied symbols:

Stop.

Does that look better? But now I see a different problem here.
The (Oracle Library code) sqlcxt was found in $ORACLE_HOME/lib/libclient.a
using nm -f; which is already in the Include Path!!.

(As you might have guessed; ORACLE_HOME=/opt/oracle_8.05).

Lines in the Makefile that trigger this are:



$(EXE) : $(OBJC) $(SRC)/wsi_mgr.pc
@echo Executable $(@F) :: Source $?
$(CC) $(CFLAGS) -c $(@F).c -o $(OBJC)
$(CC) $(CFLAGS) -o $(EXE) $(OBJC) \
-I$(ORACLE_HOME)/precomp/public -I$(ORACLE_HOME)/lib \
$(WSI_LIB) $(STD_LIB)
rm -f *.c
rm -f $(OBJC)
@echo "Done!!"

$(OBJC) : $(SRC)/wsi_mgr.pc $(C_INCLUDES)
@echo Target $(@F) :: Source $?
$(PROC) $(PROCFLAGS) iname=$? oname=$(WSI_C)

...where EXE=wsi_mgr; CFLAGS=-Ae, WSI_LIB=../obj/wsi_lib.a; and
STD_LIB = ../obj/std_lib.a


Any help will help.
Thanks.

I have an ancient booklist from the last millenium, unfortunately I
can't find any updated version on the net (any pointers anyone?).

I'd start with one of those in section `Programming' (haven't checked
whether they contain an answer to the OP's specific problem, but I
would guess so).

Thanks all of you for the advise which was well taken.

The actual problem was not using unorganized -L or -l;
it was bad usage: meaning not including the proper Oracle Library.

Found the answer in dbforms.com that sqlcxt was defined in -lclnsh.
that solved the problem.

Ralf: I will still read the suggested books for better understanding of
linking.

Thanks all.
