//////////////////////////////////////////////////////////////////////////////// 操作mongodb:

安装pcre: sudo apt-get install libpcre3

安装scons: 版本:2.3.0 sudo apt-get install scons

安装boost: 版本:boost_1_58_0 1.解压缩 2.进入目录，输入命令(可能有多余的，但都输不会出错的): sudo ./bootstrap.sh sudo ./bjam sudo ./b2 sudo ./b2 install

安装mongodb: 版本:mongodb-src-r3.0.5 1.解压缩 2.在usr/local/里建立目录/mongo/(目录可以自己选，记住就行) 3.进入目录，输入命令: sudo scons all sudo scons --prefix=/usr/local/mongo　install 4.看一下/usr/local/mongo/目录下有没有一个bin目录，有的话就好了

使用mongodb: 1.进入/usr/local/mongo/目录，建立/data/db/目录 2.进入/usr/local/mongo/bin/目录，运行命令: sudo ./mongod --dbpath /usr/local/mongo/data/db sudo ./mongo

安装C++ Drive: http://dl.mongodb.org/dl/cxx-driver/ 版本:mongo-cxx-driver-v2.4 1.解压缩 2.进入目录，运行命令: 　sudo scons --extrapath=/home/bdccl/Downloads/boost_1_58_0　　(PS:此为boost解压的地址) 　　　　　sudo scons install sudo ldconfig /usr/local/lib

测试: #include #include "mongo/client/dbclient.h" using namespace std; using namespace mongo;

void run() { DBClientConnection c; c.connect("localhost:27017"); //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; }

报错1：xtime.hpp的错误,进入文件，修改权限为可以写入(sudo chomd 777 xtime.hpp)，将里面所有的TIME_UTC改为TIME_UTC_; 报错2：链接库错误(undefined reference to 'mongo::DBClientConnection::numConnections')编译命令中加入 　　　　　-pthread -lmongoclient -lboost_thread -lboost_filesystem -lboost_program_options -lboost_system -lssl -lcrypto

/////////////////////////////////////////////////////////////////////////////// 调用python:

头文件引用(Python.h路径): #include "python2.7/Python.h"

需要链接的包: ../../../../../../usr/lib/python2.7/config-x86_64-linux-gnu/libpython2.7.so ../../../../../../lib/x86_64-linux-gnu/libpthread-2.19.so ../../../../../../lib/x86_64-linux-gnu/libutil-2.19.so ../../../../../../usr/lib/x86_64-linux-gnu/libz.so ../../../../../../lib/x86_64-linux-gnu/libdl-2.19.so

基本调用方法:

#include #include "python2.7/Python.h" using namespace std;

int main(int arg, char **argc) { Py_Initialize(); PyRun_SimpleString("import sys; sys.path.insert(0, '/home/bdccl/Documents/lb/WeiboProcess/WeiboProcess')"); if(!Py_IsInitialized()) { cout<<"Init fail"<<"\n"; return 1; } cout<<"Init success"<<"\n";

PyObject *pModule = NULL;
PyObject *pFunc = NULL;
pModule = PyImport_ImportModule("test");
if(!pModule)
{
    cout<<"get test fail"<<"\n";
    return 1;
}
cout<<"get test success"<<"\n";

pFunc = PyObject_GetAttrString(pModule, "HelloWorld");
cout<<"pFunc test success"<<"\n";
PyEval_CallObject(pFunc, NULL);
cout<<"pyEval test success"<<"\n";


Py_Finalize();
return 0;

}
