本文详细介绍了如何解决ROS项目中遇到的依赖缺失错误和代码中出现的缺失声明错误，通过安装必要的库文件和修复代码片段，最终成功使项目编译通过并运行。文中还提到了在不完全解决问题的情况下，推荐使用特定命令来避免不必要的编译错误。

1. apt-file is a good tool to use.
It has been installed and updated by

$ sudo apt-get install apt-file
$ sudo apt-file update

2. missing file error and correction:

3. Error of missing declaration:
/home/wang/ros/ccny_vision/ar_pose/src/ar_multi.cpp:71:9: error: ‘th_confidence_’ was not declared in this scope
/home/wang/ros/ccny_vision/ar_pose/src/ar_multi.cpp: In member function ‘void ar_pose::ARSinglePublisher::camInfoCallback(const CameraInfoConstPtr&)’:
/home/wang/ros/ccny_vision/ar_pose/src/ar_multi.cpp:142:13: error: ‘cam_sub_1’ was not declared in this scope
/home/wang/ros/ccny_vision/ar_pose/src/ar_multi.cpp: In member function ‘void ar_pose::ARSinglePublisher::getTransformationCallback(const ImageConstPtr&)’:
/home/wang/ros/ccny_vision/ar_pose/src/ar_multi.cpp:215:78: error: ‘th_confidence_’ was not declared in this scope

$ vi src/ar_multi.cpp +71
$ vi include/ar_multi.h +100   # check the thing that added. May lost the original corrected file via svn. Now it is ok.

4. another small error.

5. $make
It is ok now.

PS: Since not all the errors have been corrected, such as dependencies of ccny_vision, should NOT use

rosmake --rosdep- install

just do "make" in the ar_pose package would be fine.
