Mongo C++驅動程序：mongo/client/dbclient.h：沒有這樣的文件或目錄

Question

我想在我的機器上安裝MongoDB C++驅動程序。我按照指示here，並且一切都似乎安裝成功。不過，我似乎無法包含標題。下面是一個簡單的測試程序：

#include <cstdlib> 
#include <iostream> 
#include "mongo/client/dbclient.h" 

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

int main() { 
    try { 
    run(); 
    std::cout << "connected ok" << std::endl; 
    } catch(const mongo::DBException &e) { 
    std::cout << "caught" << e.what() << std::endl; 
    } 

    return EXIT_SUCCESS; 
} 

這裏是我得到的錯誤：

g++ app/tutorial.cpp -pthread -lmongoclient -lboost_thread-mt -lboost_filesystem -lboost_program_options -lboost_system -o tutorial 
app/tutorial.cpp:3:35: error: mongo/client/dbclient.h: No such file or directory 
app/tutorial.cpp: In function ‘void run()’: 
app/tutorial.cpp:6: error: ‘mongo’ has not been declared

app/tutorial.cpp:14: error: ‘e’ was not declared in this scope 
app/tutorial.cpp:14: error: expected `;' before ‘)’ token 

任何幫助將不勝感激。

行app/tutorial.cpp:3:35: error: mongo/client/dbclient.h: No such file or directory表示g ++找不到安裝的標題。在你的聯繫，下面的方框建議編譯命令狀態

You may need to use -I and -L to specify the locations of your mongo and boost headers and libraries.

的教程中，我會假設安裝過程中/usr/local/lib放在/usr/local/include和庫（例如libmongoclient.a）你的頭文件。然後，嘗試使編譯命令適應於讀取

g++ -I/usr/local/include -L/usr/local/lib -pthread -lmongoclient -lboost_thread-mt -lboost_filesystem -lboost_program_options -lboost_system app/tutorial.cpp -o tutorial
