Hi ShreeDevi Thanks for your advice anyway, it got me thinking about the problem in other ways. I'm pleased to say that I managed to get a build script that works using the following versions of the libs:
LIBJPEG_VERSION=9b ZLIB_VERSION=1.2.11 LIBPNG_VERSION=1.6.29 LEPTONICA_VERSION=1.71 TESSERACT_VERSION=3.04.01 I couldn't get it to work with any later versions of Leptonica (1.74.1 is the latest) or Tesseract (3.05.00 is the latest v3). Despite this, I now have a working standalone Mac version of Tesseract that I can drive from my own code! Apart from the actual files themselves, it's necessary to set 2 environment variables: TESSDATA_PREFIX - set to the parent folder for the tessdata folder DYLD_LIBRARY_PATH - set to the path up to and including the lib folder I've included my version of the build script in case anyone else needs to do something similar.
