I got the answer for the problem I was having. I am including the following
solution for the sake of the users like who may be having same problem.
After setting up the following environment, following is the steps to
compile any proc program ( ex. my_test.pc).
1 Copy the $ORACLE_HOME/precomp/demo/demo_proc.mk to the direcotory where
you have source code and then issue the following command to get the
executable.
$make -f demo_proc.mk build EXE=my_test OBJS=my_test.o
Thanks.
Overview
--------
Because of the way that the directory structure is arranged on Linux,
the Oracle Precompiler has difficulty finding standard C header files
such as stddef.h.
Even the sample applications can fail to precompile with a number of
syntax errors starting with:
Pro*C/C++: Release 8.0.5.0.0 - Production on Tue Oct 12 10:50:45 1999
(c) Copyright 1998 Oracle Corporation. All rights reserved.
System default option values taken from:
/home/oracle/v8050/app/oracle/8.0.5/precomp/admin/pcscfg.cfg
Error at line 33, column 11 in file /usr/include/stdio.h
# include <stddef.h>

This article is intended for Pro*C Developers and System Administrators on
the Linux operating system and contains information on how to avoid syntax
errors.
Correcting the Precompiler Installation on Linux
------------------------------------------------
When Precompiling the sample programs on RedHat Linux, you can encounter
syntax errors of the form noted above because of the way that the GNU C
Compiler (GCC) header files are installed. They are not found in
/usr/include which is the default location where the precompiler looks.
The default setting can be overridden by using the precompiler option
SYS_INCLUDE. When the precompiler was released, the default configuration
file:
$ORACLE_HOME/precomp/admin/pcscfg.cfg
was altered to switch this setting. The entry in the file on 8.0 is as
follows:
sys_include=($ORACLE_HOME/precomp/public,/usr/lib/gcc-lib/i386-redhat-
linux/2.7.2.3/include/,/usr/include)
However the directory:
/usr/lib/gcc-lib/i386-redhat-linux/2.7.2.3/include/
does not exist on later releases of Red Hat Linux.
To find out where the header files are found, type:
locate stddef.h
The output from the command looks similar to the following, depending
on the number of C compilers installed on the machine:
/usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/include/stddef.h
/usr/lib/gcc-lib/i386-glibc20-linux/egcs-2.90.29/include/stddef.h
/usr/lib/bcc/include/stddef.h
/usr/src/linux-2.2.12/include/linux/stddef.h
/usr/i386-glibc20-linux/include/linux/stddef.h
Of these, the correct location to use is the first in the list. After
backing up the file, modify the sys_include entry in pcscfg.cfg to:
sys_include=($ORACLE_HOME/precomp/public,/usr/lib/gcc-lib/i386-redhat-
linux/egcs-2.91.66/include/,/usr/include)
Now, the samples will build cleanly.
Since the change is made to the default configuration file, you do not
need
to change the make files.
Note: If this problem occurs on 8.1.5, the precompiler core dumps
with a stack trace similar to:
pcs()
pcmain()
lpmcall()
lpmpmai()
main()
This problem was reported as [BUG:1023403] and occurs because the error
message files for the precompiler were omitted from this release. You can
resolve the problem by copying the following files from an 8.0
installation:
$ORACLE_HOME/precomp/mesg/pcsus.msb
$ORACLE_HOME/precomp/mesg/pcsus.msg

Hey all,
My system is RedHat 6.1 and installed oracle version is 8.05. Database is
running fine. But I was trying to check if Pro*C is setup properly. I am
getting the following errors when I try to compile the sample programs. I am
able to compile C programs successfully using cc command.
Can somebody give me a clue, what could be wrong.
Thx.
