问题 I need to build tesseract without leptonica dependency for some work(to porting using emscripten). I looked into the make files and it seems tesseract requires leptonica header files and lib files in order to build. Providing header files is not an issue but i can't provide lib files because of some reason(emscripten doesn't generate lib files of leptonica). and i tried to stop tesseract asking for leptonica by editing make files but it seems i'm heading in wrong way. I'm very new to make

问题 I am using tesseract to recognize text from pdfs and I am facing some weird error. The error is Error opening data file data/tessdata/eng.traineddata Please make sure the TESSDATA_PREFIX environment variable is set to the parent directory of your "tessdata" directory. Now, I understand the meaning of this error and my path is updated to the parent directory of data folder. But the weird thing is that I don't get this error instantly when I run my code but I get it after recognizing 10-15 pdfs
