I am using OpenCV 3.2.0 on Ubuntu 64-bit and have the written following code which I call WebImageIO.cpp
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "cv.h"
#include "highgui.h"
#include <opencv2/core.hpp>
#include <opencv2/highgui.hpp>
#include <opencv2/imgproc.hpp>
#include <opencv2/imgcodecs.hpp>
#include <opencv2/videoio.hpp>
#include <math.h>
#include <windows.h>
#include "Generic.h"
#include "Palette.h"
#include "CWebImageIO.h"
using namespace cv;
ERROR_NUMBER CWebImageIO::WriteColourImageToPNGFile(BytePlane bytePlane, BYTE *bpOutputImage,
TCHAR *outputFileName)
{
int iNumBands=3;
int row, col, inputInc, inc;
BytePlane bpBufferPlane;
// Make real colour output plane
bpBufferPlane=MakeBytePlane(bytePlane.iRows, iNumBands*bytePlane.iColumns, NULL);
if (!(bpBufferPlane.Data))
return ERROR_MEMORY_ALLOCATION;
// Fill buffer plane with test values
cv::Mat outputImage=cv::Mat(bytePlane.iRows, bytePlane.iColumns, CV_8UC3);
if (!(outputImage.data))
{
FreeBytePlane(bpBufferPlane);
return ERROR_MEMORY_ALLOCATION;
}
memcpy((void *)(outputImage.data), (void *)(bpOutputImage),
bytePlane.iRows*bytePlane.iColumns*3);
if (!(imwrite((char *)outputFileName, outputImage)))
{
free(bpOutputImage);
return ErrorWritingFile(outputFileName);
}
// Cleanup
FreeBytePlane(bpBufferPlane);
return ERROR_NONE;
}
I then try to build it with the following.

I get the following error message.
