在CentOS 6.6上搭建C++运行环境并连接Oracle数据库

1、安装运行环境# yum install gcc-c++备注：此时会将gcc-c++和libstdc++-devel都安装上。2、查看g++是否安装成功
[root@MyRHEL 桌面]# g++ -v使用内建 specs。目标：x86_64-RedHat-linux配置为：../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-languages=c,c++,objc,obj-c++,java,fortran,ada --enable-java-awt=gtk --disable-dssi --with-java-home=/usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/jre --enable-libgcj-multifile --enable-java-maintainer-mode --with-ecj-jar=/usr/share/java/eclipse-ecj.jar --disable-libjava-multilib --with-ppl --with-cloog --with-tune=generic --with-arch_32=i686 --build=x86_64-redhat-linux线程模型：posixgcc 版本 4.4.7 20120313 （Red Hat 4.4.7-11）（GCC）3、测试（1）测试C语言程序testc.c
#include<stdio.h>
int main（）
{
printf（"Hello C！ "）;
return 0;
}运行：
# gcc testc.c -o testc
# ./testc（2）测试C++程序test.cpp
#include <iostream>
using namespace std;
int main（）
{
cout << "Come up and C++ me some time.";
cout << endl;
cout << "You won"t regret it！" << endl;
return 10;
}运行：
# g++ -o test1 test.cpp
# ./test14 安装OracleClient主要安装oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm和oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm。
# rpm -ivh oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm
# rpm –ivh oracle-instantclient11.2-devel-11.2.0.4.0-1.x86_64.rpm5 配置（1）配置ld.so.conf文件，填入如下内容：
# vi /etc/ld.so.conf
include ld.so.conf.d/*.conf
/usr/lib/oracle/11.2/client64/lib（2）配置/etc/hosts文件（此处填入Linux系统主机的IP地址和主机名称），填入如下内容：
# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.48.128 MyRHEL6 测试与Oracle数据库连接（1）建立一个connclient.cpp文件，输入如下内容：[root@MyRHEL test]# vi connclient.cpp#include<iostream>#include<string>#include<occi.h>using namespace std;using namespace oracle::occi;int main（）{ Environment *env; Connection *conn; Statement *stmt; string struser（"scott"）; string strpwd（"Orcl0991"）; string strconn_string（"10.208.17.206:1521/xe"）; env = Environment::createEnvironment（Environment::OBJECT）; conn = env->createConnection（struser, strpwd, strconn_string）; if（NULL！= conn） cout <<"conn success"<< endl; else cout <<"conn failed"<<endl; string strsql（"select deptno,dname from dept"）; stmt = conn->createStatement（strsql）; ResultSet *rset = stmt->executeQuery（）; while（rset->next（））{ int deptno = rset->getInt（1）; string dname = rset->getString（2）; cout<<"deptno="<<deptno<<",dname="<<dname<<endl; } stmt->closeResultSet（rset）; conn->terminateStatement（stmt）; env->terminateConnection（conn）; Environment::terminateEnvironment（env）; return0;}（2）编译运行：
[root@MyRHEL test]# g++ -o connclient connclient.cpp -L /usr/lib/oracle/11.2/client64/lib -I /usr/include/oracle/11.2/client64/ -locci -lclntsh /usr/lib64/libstdc++.so.6
[root@MyRHEL test]# ./connclient
conn success
deptno=10,dname=ACCOUNTING
deptno=20,dname=RESEARCH
deptno=30,dname=SALES
deptno=40,dname=OPERATIONS更多Oracle相关信息见Oracle 专题页面 http://www.linuxidc.com/topicnews.aspx？tid=12本文永久更新链接地址
