##go.tesseract go.tesseract is a wrapper for the tesseract OCR library (text-recognition from image/pdf).

Installation and dependencies

go.tesseract has two direct dependencies; go.leptonica and libtesseract

Make sure you have installed go.leptonica. go.leptonica has a C library dependency, please read the go.leptonica/README.md.

You are required to install the tesseract library including development headers at version 3.02.02 or later. You absolutely need 3.02.02 (or later) as go.tesseract can not compile with earlier versions of tesseract. At time of writing this version of tesseract is not in the ubuntu/debian stable repository yet.

go.tesseract uses gopkg.in for versioned releases:

go get gopkg.in/GeertJohan/go.tesseract.v1

Debian testing (jessie) package

sudo apt-get install -t testing libtesseract3 libtesseract-dev

OSX with Homebrew

Do the following before trying to go get this package:

$ brew install leptonica
$ brew install tesseract
$ export CGO_LDFLAGS="-L$(brew --prefix leptonica)/lib -L$(brew --prefix tesseract)/lib"
$ export CGO_CFLAGS="-I$(brew --prefix leptonica)/include -I$(brew --prefix tesseract)/include"

Note: this assumes you are using the standard Brew path of /usr/local/Cellar
