Maybe problem is in "Compiled in TESSDATA_PREFIX": if you build tesseract with automake it build-in TESSDATA_PREFIX based on installation path. E.g. if you compile with prefix=/usr , tesseract will search for language data in /usr/share/tessdata. If you move your tesseract installation to other location builtin TESSDATA_PREFIX still points to /usr/share/tessdata. You can "overwrite" it only with environment variable TESSDATA_PREFIX... See [1]. 3.02 has configure argument (--disable-tessdata-prefix) that will allow not to compile in TESSDATA_PREFIX. > (Plus it fails to add a slash when appending to TESSDATA_PREFIX -- > yielding "/usr/local/sharetessdata") > > Issue with appending slash to TESSDATA_PREFIX is IMHO quite known issue (try to google for "TESSDATA_PREFIX slash" ;-) [1] http://code.google.com/p/tesseract-ocr/source/browse/trunk/ccutil/mainblk.cpp?r=677#56 -- Zdenko -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
