Tesseract crash in Recognize()

[scubess]

Hi @rhardih,
I might need your help. I built the tesseract (libtesseract.so), leptonica (liblept.so) & tiff (libtiff.so) from the makefile. I tried in my sample app. As I got the tesseract version number (4.0.0), I think there is no problem in initialising the tesseract engine.
But when I try to recognise, I got this error thrown,

@rhardih, is there anything I missed from the build, please? Also, i using tesseract 4.0.0 with 1.74.4 have any impacts to create this issue?

You should try the tesseract issue tracker for tesseract specific problems. Also, if you want help there, you are most likely to succeed, if you include a sample project or piece of code, that makes the error reproducible, for whoever decides to take a look. 👍

Thank you so much! I believe i post with an example in tesseract repo. Also, i close this issue too.
