在CentOS 6.6上搭建C++运行环境并连接Oracle数据库

# 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:posix

gcc 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
int main()
{
  printf("Hello C!\n");
  return 0;
}

运行:
# gcc testc.c -o testc
# ./testc

(2)测试C++程序test.cpp
#include    
using namespace std;                     
int main()                                 
{                                           
    cout     cout     cout     return 10;                               
}

运行:
# g++ -o test1 test.cpp
# ./test1

4 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.rpm

5 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 MyRHEL

6 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

#include

#include

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

else

cout

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

}

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
