mysql++ 安装篇

mysql++ 安装篇

1：需要安装数据库的各种头文件以及动态库如：
    

    MySQL-server-community-5.1.58-1.rhel4.i386.rpm

    MySQL-client-community-5.1.58-1.rhel4.i386.rpm

    MySQL-devel-community-5.1.58-1.rhel4.i386.rpm

    MySQL-shared-compat-5.1.58-1.rhel4.i386.rpm  （否则安装mysql++会报错，说链接客户端失败）

2：安装mysql++
   

     ./configure -> make -> make install

3：编译测试程序

[zhichen@localhost src]$ vi test.cpp
    #include  " mysql++.h "
     using   namespace  mysqlpp;
     using   namespace  std;
     int  main()
    {
         // 构造一个Connection类的对象
        Connection con( false );
         const   char *  db  =   " mysql " ,  * server  =   " 127.0.0.1 " ,  * user  =   " pos " ,  * pass  =   " pos " ;
         if  (con.connect(db, server, user, pass))
        {
            cout  <<   " success "   <<  endl;
             string  sql  =   " select * from users " ;    
            Query query  =  con.query(sql);
             if  (StoreQueryResult rs  =  query.store())
            {
                StoreQueryResult::const_iterator it;
                 for  (it  =  rs.begin(); it  !=  rs.end();  ++ it)
                {
                    Row row  =   * it;
                    cout  <<   " /t "   <<  row[ 0 ]  <<   " /t "   <<  row[ 1 ]  <<  endl;
                }
            }
             else
            {
                cerr  <<   " Failed to get item list:  "   <<  endl;
                 return   - 1 ;
            }
        }
         else
        {
            cout  <<   " Failed to connect DB "   <<  con.error()  <<  endl;
             return   - 1 ;
        }
         return   0 ;
    }

g++ -o test test.cpp -I/usr/include/mysql -I/usr/local/include/mysql++/ -L/usr/local/lib -lmysqlpp -lmysqlclient

4：执行./test
如果报错说

./test: error while loading shared libraries: libmysqlpp.so.3: cannot open shared object file: No such file or directory

 man ldconfig

vi /etc/ld.so.conf

把mysq++动态库 /usr/local/lib的路径加进去

5：再次执行测试程序
