I am trying compile and execute PCL example on QNX having SDP 7.0 evaluation version 

please find the source code below
#include <iostream>
#include <pcl/io/pcd_io.h>
#include <pcl/point_types.h>

int main (int argc, char** argv)
{
  pcl::PointCloud<pcl::PointXYZ> cloud;

  // Fill in the cloud data
  cloud.width    = 5;
  cloud.height   = 1;
  cloud.is_dense = false;
  cloud.points.resize (cloud.width * cloud.height);

  for (auto& point: cloud)
  {
    point.x = 1024 * rand () / (RAND_MAX + 1.0f);
    point.y = 1024 * rand () / (RAND_MAX + 1.0f);
    point.z = 1024 * rand () / (RAND_MAX + 1.0f);
  }

  pcl::io::savePCDFileASCII ("test_pcd.pcd", cloud);
  std::cerr << "Saved " << cloud.size () << " data points to test_pcd.pcd." << std::endl;

  for (const auto& point: cloud)
    std::cerr << "    " << point.x << " " << point.y << " " << point.z << std::endl;

  return (0);
}

command to compile 

q++ -Vgcc_ntox86_64 -std=c++14 -I /home/madhav/pcl/io/include -I /home/madhav/pcl/common/include -I /home/madhav/
boost_1_76_0 -I /usr/include/eigen3 -I /home/madhav/pcl/2d/include  pcl.cpp -o pcl

getting following error
