Assume you call this directory C:\BuildFolder. Download the Leptonica 1.68 pre-built binary package (leptonica-1.68-win32-lib-include-dirs.zip) from: http://code.google.com/p/leptonica/downloads/detail?name=leptonica-1.68-win32-lib-include-dirs.zip and unpack it to C:\BuildFolder. It looks like you downloaded source code of leptonica and not leptonica-1.68-win32-lib-include-dirs.zip e.g. you did not follow documentations.

There is only one problem - link to tesseract-ocr-3.02-vs2008.zip. And I think that "builder" can build tesseract without "Cygwin coreutils". Please be exact - write what is in documentation and what error message you got when you followed it, so we can improve it. Vague statements like "a bit confusing", "guess and download additional packages and set up many things by himself" do not help. > Also, forcing directory structure to reflect some artist's imagination is > ridiculous.

You can find it easily - just move "C:\BuildFolder\" to "C:\Projects\BuildFolder\" and build will work. Or did you find somewhere absolute path (it can happen)? Even with relative paths you "force" directory structure "..\..\..\include\leptonica". You just try force us to mix 2 different libs in one (to leptonica within tesseract). [1] http://code.google.com/p/tesseract-ocr/source/browse/trunk/vs2008/libtesseract/libtesseract.vcproj?r=702#48 I would recommend fixing allheaders.h and pushing "build copy" in SVN to > the phase where it would not depend on directory structure or God's will to > compile.

It does not make sense to distribute allheaders.h without library files. And tesseract and leptonica are multiplaform libraries. Should we push to svn binary libs for all platforms? For all compilers? Nonsense - in current status svn is too big.
