I'm trying to build Tesseract 3, namely version 3.05.00 or thereabouts.
In fact I started trying to build using the latest versions of all the libs
but had several failures, so I've backtracked to earlier versions in order
to get successful builds. The latest release versions are the following I
think:
ZLIB_VERSION=1.2.11
LIBJPEG_VERSION=9b
LIBPNG_VERSION=1.6.29
LEPTONICA_VERSION=1.74.01
TESSERACT_VERSION=3.05.00
My latest attempt succeeded to build zlib and libjpeg but failed with
libpng:
Undefined symbols for architecture x86_64:
"_inflateValidate", referenced from:
_png_inflate_claim in pngrutil.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
make[1]: *** [libpng16.la] Error 1
make: *** [check] Error 2
I've looked at the link about compiling Tesseract but it describes MacPort
and HomeBrew only for Mac deployment, which do not generate standalone
tesseract binaries. My apps need to include a runnable version of
tesseract that doesn't require any installation. I can do this for Windows
as the compiling web page gives the details, but I'm having to try to build
the standalone version for the Mac myself. This is why I'm going through
this process!
Thanks again
Peter
