Scons安装步骤：

cd build/scons

python setup.py install

view

编译驱动之前需要安装pcre 和 scons

[root@:~/mongo-cxx-driver-v1.8]#scons

经过一段时间的组建,生成libmongoclient.so：

[root@:~/mongo-cxx-driver-v1.8]#ls

authTest clientTest firstExample libmongoclient.a LICENSE.txt SConstruct whereExample

client config.log httpClientTest libmongoclient.so mongo secondExample

拷贝至 /usr/local/lib下

[root@:~/mongo-cxx-driver-v1.8]#cp libmongoclient.so /usr/local/lib

安装 boost lib

./bootstrap.sh

./bjam install --prefix=/usr

。。。。。。。。。。。。。。。。。。。。华丽分界线。。。。。。。。。。。。。。。。。。。。。。。。。

另外如果你编译MongoDB的源码需要下载依赖包
ftp://ftp.mozilla.org/pub/mozilla.org/js/js-1.7.0.tar.gz
make -f Makefile.ref

JS_DIST=/usr make -f Makefile.ref export

编译mongoDB并install

tar -xvf mongodb-src-r1.4.4.tar.gz

cd mongodb-src-r1.4.4

scons --full install

另外如果你没有boost库 ，还需要安装boost | ./bootstrap.sh -> ./bjam install --prefix=/usr/local

所有安装完后，/usr/loca include 和 libl下会有相应的mongodb的文件

。。。。。。。。。。。。。。。。。。。华丽的分界线。。。。。。。。。。。。。。

1 .C++简单连接MongoDB

#include <iostream>

#include "mongo/client/dbclient.h"

using namespace std;

using namespace mongo;

void run() {

DBClientConnection c;

c.connect("localhost"); //add port,c.connect("localhost:27017")

}

int main(void)

{

try {

run();

cout<<"connected ok"<<endl;

}catch(DBException& e){

cout<<"caught"<<e.what()<<endl;

}

return 0;

}

编译：

[root@:~/svn/mongoDB]#g++ main.cpp -lmongoclient -lboost_thread -lboost_filesystem -lboost_program_options

运行：

[root@:~/svn/mongoDB]#./a.out

connected ok

2.MongoDB自带的测试

#include <iostream>

#include "mongo/client/dbclient.h"

using namespace std;

using namespace mongo;

void run() {

DBClientConnection c;

c.connect("localhost"); //add port,c.connect("localhost:27017")

}

int main(void)

{

try {

run();

cout<<"connected ok"<<endl;

}catch(DBException& e){

cout<<"caught"<<e.what()<<endl;

}

return 0;

}

#include <iostream>

#include "mongo/client/dbclient.h"

using namespace mongo;

void printIfAge(DBClientConnection& c, int age) {

auto_ptr<DBClientCursor> cursor = c.query("tutorial.persons", QUERY( "age" << age ).sort("name") );

while( cursor->more() ) {

BSONObj p = cursor->next();

cout << p.getStringField("name") << endl;

}

}

void run() {

DBClientConnection c;

c.connect("localhost");

cout << "connected ok" << endl;

BSONObj p = BSON( "name" << "Joe" << "age" << 33 );

c.insert("tutorial.persons", p); /**< 向person表中插入数据 */

p = BSON( "name" << "Jane" << "age" << 40 );

c.insert("tutorial.persons", p);

p = BSON( "name" << "Abe" << "age" << 33 );

c.insert("tutorial.persons", p);

p = BSON( "name" << "Samantha" << "age" << 21 << "city" << "Los Angeles" << "state" << "CA" );

c.insert("tutorial.persons", p);

c.ensureIndex("tutorial.persons", fromjson("{age:1}"));

cout << "count:" << c.count("tutorial.persons") << endl; /**< 显示person表中的数据数目 */

auto_ptr<DBClientCursor> cursor = c.query("tutorial.persons", BSONObj());

while( cursor->more() ) {

cout << cursor->next().toString() << endl;

}

cout << "\nprintifage:\n";

printIfAge(c, 33);

}

int main() {

try {

run();

}

catch( DBException &e ) {

cout << "caught " << e.what() << endl;

}

return 0;

}
