The Tesseract version is 3.01 and yes I installed it afterwards. When I'm
trying to use the tesseract from command line like so,
tesseract eurotext.tiff out
then the out file has the correct output.
But when i try to consume the libraries, then the code fails.
I tried to use C++ code also even there it fails.
