Mezzofanti – Install&Run Tutorial
(Android phone – application, how-to)
This tutorial shows you how to run the Mezzofanti application from your Android SDK:
1. Download and install Android SDK
2. Download and install Android NDK
(optional) read our post on how to interface C/C++ with Java, with example on Tesseract, here.
3. Download Mezzofanti source code and patches
Note: from now on we will consider the ndk installed in [ndk_path]
4. Create directory “tesseract” in [ndk_path]/sources
5. Copy Tesseract 2.03 in [ndk_path]/sources/tesseract. Copy them directly, for example “Makefile” should be seen directly in [ndk_path]/sources/tesseract.
6. Unzip all downloaded files (step 3), in the directory [ndk_path]/sources/tesseract
7. In [ndk_path]/apps make a symbolic link to “mezzofanti_java_code”
After this step, the directory /sources/tesseract should look like:

8. Patch the Tesseract files, with this Tesseract_ccmain_patch.zip (found on the google code). Also do copy over the Android.mk file, over the original one in order to be able to compile the code.
9. In Eclipse, import the Mezzofanti project.

Hello, Mezzofanti looks like a very potential project.
While I compile this project, I found the source lack of apps/tesseract/Application.mk or something that can’t make me proceed, the error message is:
$ make APP=tesseract
Android NDK: Building for application ‘tesseract’
make: *** No rule to make target `tesseract’, needed by `ndk-app-tesseract’. Stop.
Dear user,
thank you for your feedback, please download the Application.mk file from the google code website (featured section) – http://code.google.com/p/mezzofanti/
Thank you.
Enjoy using Mezzofanti!

It really looks like an exciting project, but I have some trouble building it.
I’ve followed your instructions, but it seems like Android.mk which was downloaded from the “featured downloads” sections isn’t working. I used Tesseract 2.03, patched its ccmain, but still it’s not compiling due to files that are missing.
For example, it can’t find the file “ccutil/cprintf.cpp” – and I also can’t find such file anywhere.
I’ll appreciate if you could assist me with it.
Many Thanks,
Alon
Hi Alon
ccutil/cprintf.cpp is part of Tesseract, so you probably didn’t copy tesseract and mezzofanti files in the appropriate directories,
thus the mk file cannot find them. In order to avoid this just copy the files in corresponding directories as indicated in the tutorial on the website.
Best regards.
