Linking Error

[supriya Das]

Hello everybody,

  When i am trying to use tesseract::ChoiceIterator    bellow error is occurring. Kindly help me.

      " LNK2019: unresolved external symbol "public: __thiscall tesseract::ChoiceIterator::~ChoiceIterator(void)" (??1ChoiceIterator@tesseract@@QAE@XZ) referenced in function _wmain"

   I included following library  

                                         libtesseract302.lib

                                         libtesseract302d.lib

My code is as follow,

   tesseract::ResultIterator* ri = api->GetIterator();

tesseract::PageIteratorLevel level = tesseract::RIL_SYMBOL;

if(ri != 0) {

do {

const char* symbol = ri->GetUTF8Text(level);

float conf = ri->Confidence(level);

if(symbol != 0) {

printf("symbol %s, conf: %f", symbol, conf);

bool indent = false;

tesseract::ChoiceIterator ci(*ri);

do {

if (indent) printf("\t\t ");

printf("\t- ");

const char* choice = ci.GetUTF8Text();

printf("%s conf: %f\n", choice, ci.Confidence());

indent = true;

} while(ci.Next());

}

printf("---------------------------------------------\n");

delete[] symbol;

} while((ri->Next(level)));

}

As far as I remember there was linking problem only with with debug shared library. Release version worked fine...

Did you included both libraries at the same time?

yes i included both the libraries.  libtesseract302.lib ,libtesseract302d.lib is any other libraries are need to include?

[Quan Nguyen]

ChoiceIterator is specific to Tesseract 3.04, I believe.
