Tesseract OCR iOS

To integrate Tesseract OCR iOS into your project using Carthage, add the repository to your Cartfile and run the update command.

github "gali8/Tesseract-OCR-iOS"

carthage update

To compile the dependent libraries (png, jpeg, tiff, leptonica) and Tesseract for iOS/simulator architectures, run make inside the TesseractOCR subfolder.

This process generates the following files and directories:

• libpng.a
• libjpeg.a
• libtiff.a
• libtesseract.a
• liblept.a
• include directories for leptonica, tesseract, and image libraries.

The resulting files are automatically copied into the lib and include directories inside the TesseractOCR directory. The initial full build may take approximately 30 minutes.

Before building the libraries, ensure you have the following tools installed on your system:

• Xcode 7 with command line tools
• M4
• Autoconf
• Automake
• Libtool

By default, the build produces a "fat" library containing all architectures (arm7, arm7s, arm64, i386, x86_64) for both devices and simulators.

If you need to limit the architectures (for example, for App Store submission), set the ARCHS environment variable before running make.

export ARCHS=armv7, armv7s, arm64
