Tesseract couldn't load any languages problem

Question

I search on internet and I try change my TESSDATA_PREFIX to export TESSDATA_PREFIX=/usr/local/share/tessdata or ...share/tessract-ocr/4.00 or 5/tessdata and tesseract/tessdata** this paths is not working for me. I have eng.traineddata file on all this locations. But I'm still getting this error and I try change traineddata file from github. But I'm still getting this error.

Here is my code

#include <string>
#include <tesseract/baseapi.h>
#include <leptonica/allheaders.h>
#include <opencv2/opencv.hpp>

using namespace std;
using namespace cv;

int main(){
cv::Mat image;
string outText;
image = cv::imread("text.png",cv::IMREAD_COLOR);

tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
api->Init(NULL, "eng", tesseract::OEM_LSTM_ONLY);
api->SetPageSegMode(tesseract::PSM_AUTO);
api->SetImage(image.data, image.cols, image.rows, 3, image.step);
outText = string(api->GetUTF8Text());
cout << outText;
api->End();
    
}

My Makefile

CC = g++
PROJECT = main
SRC = main.cpp
LIBS = `pkg-config --cflags --libs opencv4 tesseract`
$(PROJECT) : $(SRC)
    $(CC) $(SRC) $(LIBS) -o $(PROJECT) 

Here is the error message

Error opening data file /usr/local/share/tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.

Answer 1

set the first parameter in Init() method to specify the file path that "eng.traineddata" located and set the 3rd parameter to OEM_DEFAULT before :

api->Init(NULL, "eng", tesseract::OEM_LSTM_ONLY);

as to : ex)

api->Init(C:\tesseract\tessdata, "eng", tesseract::OEM_DEFAULT);
