Interesting .... I used cygwin, windows 7. Generally, I installed leptonika and its dependencies, after that I installed tesseract 3.0 from the archive file.
./runautoconfig ./configure make make install I checked the config_auto.h -> /* Version number */ #define PACKAGE_VERSION "3.00" /* Official year for this release */ #define PACKAGE_YEAR "2010" Any way, I can delete a whole installation and re-install, if it helps. 2011/4/29 zdenko podobny <[email protected]> > Oleg, > > Are you sure with message?
