次のmake出力は未定義の参照を示していますが、何が原因かわかりません。誰か助けてもらえますか?

そして、これは私のmain.cの内容です:
#include <stdio.h>
#include <stdlib.h>
#include "../mongodb-mongo-c-driver/src/mongo.h"
int main(int argc, char** argv) {
int status;
mongo conn[1];
status=mongo_connect(conn, "127.0.0.1", 27017);
return EXIT_SUCCESS;
}
2日前に動作していましたが、OSを再インストールしましたが、動作しなくなり、原因がわからないようです。mongo.hが存在し、mongo.oも存在します。mongo_connectはmongo.cにあります。何か案が?
