c++ - Wheb Build pcl with visual studio 2010 I get point_types.hpp(1185): error C2146: syntax error : missing ';' before identifier 'traits' -

i use pcl library vs 2010. don't use cmake , include dll,libs , include folders.

i wrote simple program populate poitns cloud of hemisphere in pointcloud instance. here super simple code:

#include <iostream> #include <pcl\point_cloud.h> #include <pcl\impl\point_types.hpp> #include <cmath>  using namespace pcl; void addpointstocloud(pointcloud<pointxyzrgb>& cloud);  int main () {    pointcloud<pointxyzrgb> cloud;     addpointstocloud(cloud);    return 0; }     void addpointstocloud(pointcloud<pointxyzrgb>& cloud) {     double r =2;     int ntheta = 20; //number of grid points     double dtheata =  0.5*m_pi / (ntheta - 1);      int nphi = 20;     double dphi =  2 * m_pi / (nphi - 1);      (int = 0 ; < ntheta ; i++ )     {        (int j = 0 ; j < nphi ; j++)        {           double x = r * sin(i*dtheata) * cos(j* dphi );           double y = r * sin(i*dtheata) * sin(j* dphi );           double z = r * cos(i*dtheata);            pointxyzrgb p;           p.x = x;           p.y = y;           p.z = z;            p.r = static_cast<uint8_t>(255 * x / r);           p.g = static_cast<uint8_t>(255 *  y / r);           p.b = static_cast<uint8_t>(255 * z / r);             cloud.push_back(p);       }    }  } 

now when build within visual studio 2010 following errors:

error 2 error c2146: syntax error : missing ';' before identifier 'traits' c:\program files (x86)\pcl 1.6.0\include\pcl-1.6\pcl\impl\point_types.hpp 1185

error 3 error c4430: missing type specifier - int assumed. note: c++ not support default-int c:\program files (x86)\pcl 1.6.0\include\pcl-1.6\pcl\impl\point_types.hpp 1185

error 4 error c4430: missing type specifier - int assumed. note: c++ not support default-int c:\program files (x86)\pcl 1.6.0\include\pcl-1.6\pcl\impl\point_types.hpp 1185

i don't understand why, don't have compile errors before building project , is
correct in point_types.hpp (pcl header file)

please me

thank u in advance

i able simplify code error. below code induces error compiler (which gcc error same declaration yours - traits):

did try simplifying code further?

#include <pcl/point_cloud.h> #include <pcl/impl/point_types.hpp> int main () {    return 0; } 

have @ examples use point_types.hpp in pcl - there none use directly. instead, other things expected set before included. see example: adding own custom pointt type

the last code sample there instead contains following include:

#include <pcl/point_types.h> 

point_cloud.hpp included via following include in point_cloud.h (so not need included in application):

#include <pcl/impl/point_types.hpp>  // include struct definitions
