c++ - jpeg_write_view error in boost::gil -

i learning how use generic image library in boost, , following codes illustrate how write raw data jpeg file:

int main(void) {     unsigned char *src_pixels;     int src_row_bytes = 200;     src_pixels = new unsigned char [200*500];     for(int i=0; i<500; i++)     {         for(int j=0; j<200; j++)             src_pixels[i*200+j]= j;     }     char *dst_pixels;     dst_pixels = new char [200*500];     for(int i=0; i<500; i++)     {         for(int j=0; j<200; j++)             dst_pixels[i*200+j]= j;     }     gray8c_view_t my_view = interleaved_view(200,500,(const gray8_pixel_t*)src_pixels,src_row_bytes);     gray8s_view_t your_view = interleaved_view(200,500,( gray8s_pixel_t*)dst_pixels,src_row_bytes);       jpeg_write_view("c:/file_1_copy.jpg", my_view);     jpeg_write_view("c:/file_2_copy.jpg", your_view);       delete []src_pixels;      delete []dst_pixels;      return 0; } 

however, seems jpeg_write_view("c:/file_2_copy.jpg", your_view); cannot compiled, , following error messages given:

error   2   error c2338: jpeg_write_support<view>::is_supported 

i not how make compile. suggestion appreciated.
