Hello,
I am a newbie to PRO*C. I have copied a pro*c program from the net, (a .pc file) and using the pro*C editor, pre compiled it into a .c file format. But When I am running the .c file it says, Unable to open SQLCA.h. Undefined symbol &sqlca etc. Please experts tell me how to set up the C environment to run the above program.
Thanks for your time,
Amjath

There are two approaches to handle the problem.
----------------------------------------------------------------
SOLUTION #1:
------------------------------------------------------------------
a.pc file you should see #include < sqlca.h > remove it in your a.pc program and add the following before or after all you declared variables:
EXEC SQL INCLUDE sqlca;
EXAMPLE:
$ cat test.pc
#include < stdio.h >
EXEC SQL INCLUDE sqlca;
main()
{
printf("This is a testn");
return(0);
}
===========================================================
$ proc test.pc
Pro*C/C++: Release 8.1.7.2.0 - Production on Thu Apr 25 09:35:26 2002
(c) Copyright 2000 Oracle Corporation. All rights reserved.
System default option values taken from: /u01/app/oracle/product/8.1.7/precomp/g
===============================================================
You will see test.c file. Compile the test.c program
===============================================================
$ cc test.c -o test.out
$ ls test*
test.c test.lis test.out test.pc
============================================
Run executable file: test.out
============================================
$ test.out
This is a test
--------------------------------------------------------------
SOLUTION #2:
----------------------------------------------------------------
Create a makefile.
================================================================
test.pc
================================================================
$ cat test.pc
#include < stdio.h >
#include < sqlca.h >
main()
{
printf("This is a testn");
return(0);
}
$
=================================================================
$ rm test.c test.lis test.out
==============================================================
Example of makefile:
==============================================================
$ more test.mk
CC=/usr/bin/cc
ORACLE_HOME=/u01/app/oracle/product/8.1.7
PROC=$(ORACLE_HOME)/bin/proc
TARGET=test.out
SOURCE=test.pc
$(TARGET): $(SOURCE) $(SOURCE:.pc=.c) $(SOURCE:.pc=.o)
$(CC) $(LDFLAGS) -o $(TARGET)
$(SOURCE:.pc=.o) -L$(ORACLE_HOME)/lib $(PROLDLIBS)
include $(ORACLE_HOME)/rdbms/demo/demo_rdbms.mk
=================================================================
$ make -f test.mk
$ ls test*
test.c test.lis test.mk test.o test.out test.pc
$ test.out
This is a test
======================================================

Thanks Cindy,
But I could not understand most of your comments ( I am totally new to Pro C). In my Ora81/bin folder I don't have any exe files like proc.exe ( I mean, cc or cat or ls), those you have used with the $ symbol. If i have misunderstood please explain me in detail.
Thanks,
Amjath.
