QtcreatorのRosbagリーダー

Question

Qtcreatorでローズバッグリーダーを作成しようとしています。私はプロジェクトを作成し、ちょうどバッグの中の情報を読みたいと思う。

QT += core 
QT -= gui 

CONFIG += c++11 

TARGET = ROSBag_Reader 
CONFIG += console 
CONFIG -= app_bundle 

TEMPLATE = app 
LIBS += -lboost_system 
LIBS+= -lpthread 
LIBS+= -L/usr/lib/x86_64-linux-gnu 
LIBS+= -ltf2_ros 
LIBS+= -lrostime 
LIBS+= -lrospack 
LIBS+= -lroslz4 
LIBS+= -lroslib 
LIBS+= -lroscpp_serialization 
LIBS+= -lroscpp 
LIBS+= -lrosconsole_print 
LIBS+= -lrosconsole_bridge 
LIBS+= -lrosconsole_backend_interface 
LIBS+= -lrosconsole 
LIBS+= -lrosbag_storage 
LIBS+= -lrosbag 

SOURCES += main.cpp 

# The following define makes your compiler emit warnings if you use 
# any feature of Qt which as been marked deprecated (the exact warnings 
# depend on your compiler). Please consult the documentation of the 
# deprecated API in order to know how to port your code away from it. 
DEFINES += QT_DEPRECATED_WARNINGS 

# You can also make your code fail to compile if you use deprecated APIs. 
# In order to do so, uncomment the following line. 
# You can also select to disable deprecated APIs only up to a certain version of Qt. 
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0 

そして、私のmain.cppに： はここに私のプロファイルである

#include <rosbag/bag.h> 
#include <rosbag/view.h> 
#include <std_msgs/Int32.h> 
#include <std_msgs/String.h> 

#include <boost/foreach.hpp> 
#define foreach BOOST_FOREACH 


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

    rosbag::Bag bag; 
    bag.open("/home/xxx/Bureau/Developpement/ROSBag_Reader/data/dataset_table.bag", rosbag::bagmode::Read); 

    std::vector<std::string> topics; 
    topics.push_back(std::string("chatter")); 
    topics.push_back(std::string("numbers")); 

    rosbag::View view(bag, rosbag::TopicQuery(topics)); 

    foreach(rosbag::MessageInstance const m, view) 
    { 
     std_msgs::String::ConstPtr s = m.instantiate<std_msgs::String>(); 
//  if (s != NULL) 
//   std::cout << s->data << std::endl; 
/* 
     std_msgs::Int32::ConstPtr i = m.instantiate<std_msgs::Int32>(); 
     if (i != NULL) 
      std::cout << i->data << std::endl;*/ 
    } 

    bag.close(); 

} 

しかし、私はプロジェクトを実行しようとすると、私はエラーを取得：

/home/xxx/Qt/5.7/gcc_64/bin/qmake -spec linux-g++ -o Makefile ../ROSBag_Reader/ROSBag_Reader.pro 
g++ -Wl,-O1 -Wl,-rpath,/home/xxx/Qt/5.7/gcc_64/lib -o ROSBag_Reader main.o -lboost_system -L/usr/lib/x86_64-linux-gnu -ltf2_ros -lrostime -lrospack -lroslz4 -lroslib -lroscpp_serialization -lroscpp -lrosconsole_print -lrosconsole_bridge -lrosconsole_backend_interface -lrosconsole -lrosbag_storage -lrosbag -L/home/xxx/Qt/5.7/gcc_64/lib -lQt5Core -lpthread

collect2: error: ld returned 1 exit status 
Makefile:214 : la recette pour la cible « ROSBag_Reader » a échouée 

を私は「ドンこのエラーがどこに来るのか理解できません。
