我有此示例代碼:未定義參照MONGO :: curTimeMillis64()

#include <iostream> 
#include <mongo/util/time_support.h> 

using namespace std; 

int main() 
{ 
    cout << mongo::curTimeMillis64() << endl; 
    return 0; 
} 

和與編譯:

g++ -I/tmp/include prova.cpp -o prova -L/tmp/lib -lmongoclient 

結果是:

/tmp/ccH0vDvx.o: In function `main': 
prova.cpp:(.text+0x5): undefined reference to `mongo::curTimeMillis64()' 
collect2: error: ld returned 1 exit status 

我使用mongo cxx驅動程序的26compat和我也與nm檢查庫內的符號:

nm /tmp/lib/libmongoclient.so | grep curTime 
00000000000ea510 t _ZN5mongo13curTimeMicrosEv 
00000000000ea4f0 t _ZN5mongo15curTimeMicros64Ev 
00000000000ea440 t _ZN5mongo15curTimeMillis64Ev 

一切似乎都沒問題,但編譯失敗。有什麼建議麼?

感謝
