libPocoMongoDB.so.71: cannot open shared object file: No such file or directory

I am using poco library to connect to mongodb. My code is getting compiled but while running out file it is giving me the below error

./test_mongo: error while loading shared libraries: libPocoMongoDB.so.71: cannot open shared object file: No such file or directory

libPocoMongoDB.so.71 is already existing at /usr/local/lib

Here is my c++ code

#include "Poco/MongoDB/MongoDB.h"
#include "Poco/MongoDB/Connection.h"
#include "Poco/MongoDB/Database.h"
#include "Poco/MongoDB/Cursor.h"
#include "Poco/MongoDB/Array.h"


int main(int argc, char** argv)
{


    try
    {
            Poco::MongoDB::Connection connection("localhost", 27017);
    }
    catch (Poco::Exception& exc)
    {
            std::cerr << exc.displayText() << std::endl;
    }

    return 0;
 }

I compiled it using below command

g++ -o test_mongo test_mongo.cpp -I/usr/local/include -L/usr/local/lib/ -lPocoMongoDB -lPocoNet -lPocoFoundation
Solution

  • There are two ways to resolve it

    1. Try the ldconfig command.
    2. Just move all the libraries from /usr/local/lib to /usr/lib.
