las转pcd格式编译不通过的问题（7月24号未解决）

las2pcd.cpp如下： 

#include <iostream>
#include <cstdlib>
#include <liblas/liblas.hpp>//liblas tou wen jin
#include <pcl/io/io.h>
#include <pcl/io/pcd_io.h>
#include <pcl/point_types.h>

#include <liblas/reader.hpp>
#include <liblas/factory.hpp>
#include <liblas/detail/fwd.hpp>
#include <liblas/point.hpp>

using namespace std;

int main (int argc, char** argv)
{
    std::ifstream ifs(argv[1], std::ios::in | std::ios::binary); // 打开las文件
    liblas::ReaderFactory f;
    liblas::Reader reader = f.CreateWithStream(ifs); // 读取las文件

	unsigned long int nbPoints=reader.GetHeader().GetPointRecordsCount();//获取las数据点的个数

	pcl::PointCloud<pcl::PointXYZRGB> cloud;
	cloud.width    = nbPoints;	//保证与las数据点的个数一致	
	cloud.height   = 1;			
	cloud.is_dense = false;
	cloud.points.resize (cloud.width * cloud.height);

	int i=0;				
	uint16_t r1, g1, b1;	
	int r2, g2, b2;			
	uint32_t rgb;
