"hello World Example" for C++

[schueffp at mskcc.org]

Dear OpenSlide People,

for Java and Python, there are hello world examples how to use openSlide.

But for C++, I had a hard time to find such a script, which e.g. creates a openSlide object, reads a .SVS file and outputs the SVS info in the console.

Is there anybody who has that and likes to share?

I tried following code, but it constantly gives errors:


#include "stdafx.h"
#include <iostream>
#include <sys/stat.h>
#include <string>
#include "../../../../../Downloads/openslide-win64-20150527/openslide-win64-20150527/include/openslide/openslide.h"
#include <stdio.h>

using namespace std;


int main()
{
const char *filename = "CMU-1.svs“; // file exists
openslide_t* osr = openslide_open(filename);



openslide_close(osr);

return 0;
}


The error is:

1>ConsoleApplication1.obj : error LNK2019: Verweis auf nicht aufgelöstes externes Symbol "__imp_openslide_open" in Funktion "main".
1>ConsoleApplication1.obj : error LNK2019: Verweis auf nicht aufgelöstes externes Symbol "__imp_openslide_close" in Funktion "main“.

It translates to
error LNK2019: Reference to unresolved external symbol … in function main.

I think I have to include some dll, but I dont have a clue which and how. I am using Visual Studio 2015 and the latest openSlide ( openslide-win64-20150527 ). Or shoud I use the openslide-3.4.1 download?

Thank you very much!!

Best,
 Peter
