I discuss some of the issues on the tesseract-ocr developers forum in the "Enhancing the tesseract 3.01 Visual Studio 2008 distribution" thread (http://groups.google.com/group/tesseract-dev/browse_thread/thread/75be5c97eb4d1b3c). I'm still working on the README for my "enhanced" vs2008 package (I got a bit of writer's block while completing the "Programming libtesseract section), but here's a relevant quote: Add the following :guilabel:`Preprocessor Definitions` when compiling any files that include `baseapi.h` and you are linking with the static library versions of `libtesseract`:: __MSW32__;USE_STD_NAMESPACE If you are linking with the DLL versions of `libtesseract` instead add:: __MSW32__;USE_STD_NAMESPACE;TESSDLL_IMPORTS;CCUTIL_IMPORTS;LIBLEPT_IMPORTS -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
