Build error for Chapter 4 code (Visualization.cpp)

[amiltonwong]

Dear all,
I have troubles in building chapter 4 code (Visualization.cpp)

/root/opencv_ws/Chapter4_StructureFromMotion/Visualization.cpp:97:2: error: ‘toROSMsg’ is not a member of ‘pcl’
pcl::toROSMsg(mesh_cld,pm.cloud);
^

The detailed error can be viewed here:
https://gist.github.com/amiltonwong/72745b90a2d5e70a7e47

My system is ubuntu 14.04, CUDA 7.5, opencv 2.4.8, and ROS Indigo installed.

The error seems come from : toROSMsg

Could someone suggest me how to fix it?

THX~
Milton

With pcl-1.8, toROSMsg is deprecated, but the library provides functions to handle this.

Just add #include <pcl/ros/conversions.h> to Visualization.cpp.
