Issue with declaring Tesseract OCR TessBaseAPI - visual-studio-2013

Question

I am new to Tesseract API. Currently I am running the sample program from the Wiki on Visual Studio 2013, and the program is as follows.
#include "leptonica\allheaders.h"
#include "iostream"
#include "api\baseapi.h"
#include "stdio.h"
using namespace std;
using namespace tesseract;
int main(int argc, char** argv)
{
char* outText;
TessBaseAPI *api = new TessBaseAPI();
// Initialize tesseract-ocr with English, without specifying tessdata path
if (api->Init(NULL, "eng"))
{
fprintf(stderr, "Could not initialize tesseract.\n");
exit(1);
}
// Open input image with leptonica library
Pix *image = pixRead("/usr/src/tesseract-3.02/phototest.tif");
api->SetImage(image);
// Get OCR result
outText = api->GetUTF8Text();
printf("OCR output:\n%s", outText);
// Destroy used object and release memory
api->End();
delete[] outText;
pixDestroy(&image);
return 0;
}
When I compile this with VS2013, I get the following errors.
1>------ Build started: Project: OCRTest, Configuration: Debug Win32 ------
1> main.cpp
1>c:\tesseract-build\include\leptonica\pix.h(209): warning C4305: 'initializing' : truncation from 'double' to 'const l_float32'

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
I believe I have not built the tesseract source properly, but I cannot be sure. Also, declaring
TessBaseAPI * api = new TessBaseAPI()
throws up errors such as 'type specifier expected' when cursor is moved over TessBaseAPI(). Help would be greatly appreciated, and thank you in advance!

Answer 1

Assuming that you are using Tesseract 3.02.02 & leptonica 1.68 library.
Follow these steps.
Remember to check Tesseract Development files option when installing Tesseract
Add below Include folders in Project solutions -> VC++ Directories
C:\Program Files\Tesseract-OCR\include
C:\Program Files\Tesseract-OCR\include\tesseract
C:\Program Files\Tesseract-OCR\include\leptonica
Add below lib folder in Project solutions -> VC++ Directories
C:\Program Files\Tesseract-OCR\lib
Add additional dependencies in Configuration Properties -> Linker->Input ->Additional Dependencies
libtesseract302.lib
libtesseract302d.lib
liblept168.lib
liblept168d.lib
