# ocreval

[![Build Status](https://travis-ci.org/eddieantonio/ocreval.svg?branch=master)](https://travis-ci.org/eddieantonio/ocreval)

The `ocreval` consist of 17 tools for measuring the

performance of and experimenting with OCR output. See [the user

guide][user-guide] for more information.

[user-guide]: https://github.com/eddieantonio/ocreval/raw/master/user-guide.pdf

`ocreval` is a modern port of the [ISRI Analytic Tools for OCR Evaluation][isri],

with UTF-8 support and other improvements.

See [the archived Google Code repository of the original

project][isri-code]!

# Install (macOS)

Using [Homebrew][brew]:

    brew install eddieantonio/eddieantonio/ocreval

[brew]: http://brew.sh/

Building

========

To build the library and all of the programs, ensure that you have all

required [dependencies](#dependencies).

## Dependencies

`ocreval` requires [utf8proc](https://github.com/JuliaStrings/utf8proc)

to build from source.

### macOS

Using [Homebrew][brew]:

    brew install utf8proc

### Ubuntu/Debian

You may need to install `make` and a C compiler:

    sudo apt install build-essential

Then install, `libutf8proc-dev`:

    sudo apt install libutf8proc-dev

If `libutf8proc-dev` cannot be installed using `apt`, follow

[Other Linux](#other-linux) below

### Other Linux

Install `libutf8proc-dev` manually:

    curl -OL https://github.com/JuliaStrings/utf8proc/archive/v1.3.1.tar.gz

    tar xzf v1.3.1.tar.gz

    cd utf8proc-1.3.1/

    make

    sudo make install

    # Rebuild the shared object cache - needed to load the library

    # at runtime 

    sudo ldconfig

    cd -

## Building the tools

Once all dependencies are installed, you may compile all of the

utilities using `make`:

    make

## Installing

Install to `/usr/local/`:

    sudo make install

Note: You will not need `sudo` on macOS if you have `brew` installed.

## Installing "locally"

This will not copy any files at all, but instead create the appropriate

shell commands to add all executables, man pages, and libraries to

the correct path (replace `~/.bashrc` with your start-up file):

    make exports >> ~/.bashrc
