tesseract-ocr how to includ baseapi.h

Question

I followed the instructions I found in form of tessesract on how to includ baseapi.h.

i am using:

vs2010
Version tesseract 3.01

i try to understand how to use baseapi.h.

test program:

#define __MSW32__

 #include "baseapi.h"

using namespace  tesseract;

int _tmain(int argc, _TCHAR* argv[])

{

   TessBaseAPI *myTestApi;

   myTestApi=new TessBaseAPI();

   //myTestApi->Init("d:/temp.jpg","eng");

   return 0;

}

form gide:

add the following folders to Additional Include Directories (properties) - to resolve file not found issues after including "baseapi.h"

tesseract-3.01/api

tesseract-3.01/ccmain

tesseract-3.01/ccutil

tesseract-3.01/ccstruct

added the following libs to "Properties/Linker/Input/Additional Dependancies" in order to use the Tesseract and Leptonica libs libtesseract.lib;liblept.lib

// added the following paths to "Properties/Linker/General/Additional Library Directories" in order to find the Tesseract and Leptonica libs tesseract-3.01/vs2010/Release tesseract-3.01/vs2008/lib

And I try to run now

So I try to find libs libtesseract.lib and replaced with libtesseract_tessopt.lib and then run

1>------ Build started: Project: test4, Configuration: Debug Win32 ------
1>  test4.cpp
1>test4.obj : error LNK2019: unresolved external symbol "public: __thiscall tesseract::TessBaseAPI::TessBaseAPI(void)" (??0TessBaseAPI@tesseract@@QAE@XZ) referenced in function _wmain

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Is anything known solution to the problem?

thanks,

Solution

This is what I did to compile it:

1.) Copy all header files into one includedirectory, so later only §(TESS_DIR)\include has to be added to the include directories.

copy the leptonica headers into $(TESS_DIR)\include\leptonica.

2.) Open vs2010\tesseract.sln and compile all configurations. Then copy all lib files into $(TESS_DIR)\lib\debug and $(TESS_DIR)\lib\release. Then add those directories to the build settings.

3.) Copy the compiled libtesseract.dll and liblept168.dll as well as the folder tessdata, containg eng.traineddata, to the Release folder of your project.

4.) Add these libraries as additional dependencies:

libtesseract.lib
liblept168.lib

5.) #include <baseapi.h>
