Configure precompilation parameters for pro * c Programs in linux

In the linux environment, configure the precompiled parameters of the pro * c program-general Linux technology-Linux programming and kernel information. For more information, see the following. Operating System:

Red Hat Linux 2.4.21-4.EL

Database: oracle10g

Configuration steps:

1. Create an etc directory under $ HOME. In this directory, resume a configuration file Make. defines, edit the file, and write the following content:

Include $ (ORACLE_HOME)/precomp/lib/env_precomp.mk

PROC = proc
GCC = gcc

BINDIR = $ (HOME)/bin

# Oracle include directory

ORAIFLAG =-I $ (ORACLE_HOME)/rdbms/public-I $ (ORACLE_HOME)/rdbms/demo-I $ (ORACLE_HOME)/precomp/public-I $ (ORACLE_HOME) /plsql/public

# Oracle database file path

ORALFLAG =-L $ (ORACLE_HOME)/lib-L $ (ORACLE_HOME)/precomp/lib-L $ (ORACLE_HOME)/rdbms/lib-L $ (ORACLE_HOME) /sqlplus/lib-L $ (ORACLE_HOME)/network/lib-L $ (ORACLE_HOME)/plsql/lib

IFLAG =-I $ (HOME)/include $ (ORAIFLAG)
LFLAG =-L $ (HOME)/lib $ (ORALFLAG)-lclntsh

PROCFLAGS = char_map = string

. SUFFIXES:. pc. c. o
. Pc. c:
$ (PROC) $ (PROCFLAGS) iname = $ *
Rm *. lis
. Pc. o:
$ (PROC) $ (PROCFLAGS) iname = $ *
Rm *. lis
$ (GCC) $ (IFLAG)-c $ *. c
. C. o:
$ (GCC) $ (IFLAG)-c $ *. c


2. Make sure that the. bash_profile file contains the following environment variable Configuration:

Export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: $ ORACLE_HOME/lib

3. Write the following statement in the first line of your makefile:

Include $ (HOME)/etc/Make. defines

Other makefile writing methods remain unchanged.

Example:

I have a source program test. pc. The content of my makefile file is as follows:

Include $ (HOME)/etc/Make. defines
All: test
Test: test. o
$ (GCC) $? -O $ @ $ (LFLAG)
Rm./tp *./*. c./*. o
Run make test during compilation.

Generate the test executable program.

Note: The above configuration method is related to the author's program organization habits (generally, the General Compilation parameters are put in a file, and the specific makefile file then includes this definition ). In short, you can write all the statements mentioned above in the makefile file.
