liblept168.dll

liblept168.lib

Hi,

Thanks!!

Actually, I would like to have version 1.71 and Tesseract 3.03-rc1 for
Windows x86 and x64. Would you be able to provide builds for those as well?

FYI, I've just updated the presets to include the newest versions of
Leptonica and Tesseract on Windows x86 and x64 as well:

Hi, Thanks for the reply and I could not get my solution there.
Also I tried of building libraries,(DLL) for 32-bit windows using VS2010 by the help of http://www.leptonica.com/vs2008doc/building-liblept.html
But I cant build it for x64 configuration, any help would be greatly appreciated.

Thanks,
Siva.

Well, it's working fine here under x64 Windows, so if you have any more
info, like error messages, and what not, I should be able to help you.
Let me know, thanks!

Hi,
  You can find the errors here, and refer the attached file for more errors.
 (I just changed the from 32 to 64 and build-ed it)

Ok, but what happens if you follow the instructions at the URL below
without rebuilding anything?

I couldn't find anything related to building on win x64 there(github). Hence I have followed the Leptonica site.
it only works for 32 bit configuration.
thanks.
