error: ‘class QComboBox’ has no member named ‘setCurrentText’; did you mean ‘currentText’?

An error in ros_gui folder

In member function ‘void Ui_MainWindow::retranslateUi(QMainWindow*)’:
/home/htf/rosbuild_ws/src/rec_gui/src/../build/ui_mainwindow.h:346:19: error: ‘class QComboBox’ has no member named ‘setCurrentText’; did you mean ‘currentText’?
         x_cn_num->setCurrentText(QApplication::translate("MainWindow", "0", 0, QApplication::UnicodeUTF8));

error: no matching function for call to ‘std::vector<std::pair<pcl::PointXYZ, cv::Point_<float> > >::vector(int, std::pair<pcl::PointXYZ, int>)’

when compiling the ros_exploration package, I received an error as below.

In member function ‘void Planning::find_farest_point(pcl::PointCloud<pcl::PointXYZ>::Ptr, PointT, PointT, float, bool)’:
/home/htf/rosbuild_ws/src/ros_exploration/src/planning.cpp:892:95: error: no matching function for call to ‘std::vector<std::pair<pcl::PointXYZ, cv::Point_<float> > >::vector(int, std::pair<pcl::PointXYZ, int>)’
     std::vector<std::pair<PointT,cv::Point2f> > _candidate_points(3,make_pair(PointT(0,0,0),0));

请问该项目是使用哪种避障方法实现的?怎么编译？

undefined reference to symbol '_ZN5boost6system15system_categoryEv'

when compiling the SLAM package, I got an error like this

/usr/bin/x86_64-linux-gnu-ld: CMakeFiles/SLAM.dir/src/ros_mono.cc.o: undefined reference to symbol '_ZN5boost6system15system_categoryEv'
/usr/lib/x86_64-linux-gnu/libboost_system.so: error adding symbols: DSO missing from command line

Then I followed the solution listed in [https://github.com/raulmur/ORB_SLAM2/issues/494]
add -lboost_system into CMakeLists.txt

set(LIBS 
${OpenCV_LIBS} 
${EIGEN3_LIBS}
${Pangolin_LIBRARIES}
${PROJECT_SOURCE_DIR}/Thirdparty/DBoW2/lib/libDBoW2.so
${PROJECT_SOURCE_DIR}/Thirdparty/g2o/lib/libg2o.so
${PROJECT_SOURCE_DIR}/lib/libORB_SLAM2.so
-lboost_system)

however, I can't fix this problem.

usr/bin/x86_64-linux-gnu-ld: cannot find -lvtkCommon usr/bin/x86_64-linux-gnu-ld: cannot find -lvtkFlitering

when compiling the SLAM package, I got two errors like the title at the end.
