*This is a plea for help!* Anyone interested in seeing 3.00 this side of August?
Here is the status: Linux: Preliminary alpha release compiles and runs. It is slower than 2.04, due to the new page layout analysis, but the benefits are supposed to outweigh that: Page layout analysis. *Lots* of languages. more... In theory the linux version should compile and link happily with leptonica, given the right combination of apt-gets. Not tested yet, as I have been bogged down with windows: Windows: Preliminary alpha release also compiles and runs *without leptonica only*. DLL is broken due to API change. I only have very little time left before I will be away for a while, but I was hoping to post a pre-alpha version to svn for people to try. The problem is that there is no chance of getting the windows version to work with leptonica any time soon, and without it the flagship page layout analysis won't work properly. Here is the problem: Leptonica depends on the following lower-level libraries: libjpeg, libpng, libtiff, zlib. DLLs for these are all available for windows, but they are all compiled to use msvcrt.dll. Tesseract and Leptonica will not work unless they use the same crt (C-runtime) as the libraries, and VC++2008, which everyone wants to use will not (without jumping through more hoops than I can ask an average tesseract user to do) build anything to use msvcrt.dll. You must use either a statically linked crt, or use msvcr90.dll, a newer version that contains .net stuff that tesseract doesn't care about. *What I need are statically linked versions of the 4 libraries above compiled to use a statically linked crt (/MT option) and possibly their dependencies.* Alternatively, libraries built for the new msvcr90.dll (/MD) would do, but that would mean everybody has to have the VC++2008 distributables. It might help dll users though, when it is eventually working again. *This is not an easy task, as most of the sources for these libraries don't have vcproj/sln projects with which to build them.* If anyone is sufficiently expert with VC++2008 and building other people's code, and understands what I am talking about, I would be grateful for the help. The other viable alternative would be to compile letonica without image i/o at all, and leave tesseract still unable to read anything other than compressed tiff. Ray. PS A good place to get all these libraries is: http://gnuwin32.sourceforge.net/packages/*.htm, where * is tiff, jpeg, libpng, or zlib.
