在CentOS 6.6上搭建C++运行环境并连接Oracle数据库

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：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#includeint 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# ./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.confinclude 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/hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.48.128 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#include#includeusing 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 elsecout 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]# ./connclientconn successdeptno=10,dname=ACCOUNTINGdeptno=20,dname=RESEARCHdeptno=30,dname=SALESdeptno=40,dname=OPERATIONS
