Ubuntu16.04跑loam_velodyne

Ubuntu16.04，ros kinetic

其实按照github上的README.md来编译就好

cd ~/catkin_ws/src

git clone https://github.com/laboshinl/loam_velodyne.git

cd ..

catkin_make -DCMAKE_BUILD_TYPE=Release

报错：

/loam_velodyne-master/src/lib/LaserMapping.cpp:149:28: error: ‘downSizeFilterMap’ was not declared in this scope
downSizeFilterMap().setLeafSize(fParam, fParam, fParam);

在github的issue中查找报错，找到loam_velodyne-master/src/lib/LaserMapping.cpp下的149行，将这几行注释掉

/*
/// unused code 
if (privateNode.getParam("mapFilterSize", fParam))
{
if (fParam < 0.001)
{
ROS_ERROR("Invalid mapFilterSize parameter: %f (expected >= 0.001)", fParam);
return false;
}
else
{
downSizeFilterMap().setLeafSize(fParam, fParam, fParam);
ROS_INFO("Set map down size filter leaf size: %g", fParam);
}
}
*/

再source一下就好了：

source ~/catkin_ws/devel/setup.bash
