【问题描述】:
以下代码:
#include <ros/ros.h>
#include <pcl_ros/point_cloud.h>
#include <pcl/point_types.h>
#include <boost/foreach.hpp>
typedef pcl::PointCloud<pcl::PointXYZ> PointCloud;
void callback(const PointCloud::ConstPtr& msg)
{
printf ("Cloud: width = %d, height = %d\n", msg->width, msg->height);
BOOST_FOREACH (const pcl::PointXYZ& pt, msg->points)
printf ("\t(%f, %f, %f)\n", pt.x, pt.y, pt.z);
}
int main(int argc, char** argv)
{
ros::init(argc, argv, "sub_pcl");
ros::NodeHandle nh;
ros::Subscriber sub = nh.subscribe<PointCloud>("points2", 1, callback);
ros::spin();
}
这是取自here的默认示例
我的 CMake:
cmake_minimum_required(VERSION 2.6 FATAL_ERROR)
find_package(PCL 1.3 REQUIRED COMPONENTS common io)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
target_link_libraries(${PROJECT_NAME} ${PCL_COMMON_LIBRARIES} ${PCL_IO_LIBRARIES})
pcl官方website推荐的具体配置是什么
我仍然收到以下链接错误:
CMakeFiles/apsp_manifold.dir/src/apsp_manifold.cpp.o: In function `void pcl::detail::FieldMapper<pcl::PointXYZ>::operator()<pcl::fields::z>()':

上面描述的错误是怎么回事?如何消除它?
【问题讨论】:
-
尝试
make VERBOSE=1并检查编译器选项是否存在适当的库……看起来有些库已经搞砸了。 -
