添加编译参数，例如：
- add_definitions(-DDEBUG)将在gcc命令行添加 DEBUG 宏定义；
- add_definitions(“-Wall -ansi –pedantic –g”)
编译时有时出现报警warning: extra ‘;’ [-Wpedantic]，很影响看编译信息，可使用下面方法禁止pedantic
//save compiler switches
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wpedantic"
//Bad headers with problem goes here
#include <ros/ros.h>
#include <sensor_msgs/LaserScan.h>
//restore compiler switches
#pragma GCC diagnostic pop
类似的报警还有
warning: ISO C++ forbids variable length array ‘angle_compensate_nodes’ [-Wvla]，把上面的"-Wpedantic"换成"-Wvla"即可Recommend
