Tess4j unsatisfied link error on mac OS X
java, tesseract
Solution
I know it's an old post. I had this problem too recently when I tried to use `Tess4J`. However, I managed to find a way around it. I've written a post about it http://www.microshell.com/programming/java/performing-optical-character-recognition-in-java/
In short, the problem is because `tess4j-2.0.0.jar` doesn't include MacOS library. So I just modified the maven cached jar on mine by doing these steps:
- `cd /Users/user/.m2/repository/net/sourceforge/tess4j/tess4j/2.0.0` (adjust the directory where your tess4j JAR file resides)
- `mkdir darwin`
- `jar uf tess4j-2.0.0.jar darwin`
- `cp /opt/local/lib/libtesseract.3.dylib darwin/libtesseract.dylib`
- `jar uf tess4j-2.0.0.jar darwin/libtesseract.dylib`
- `jar tf tess4j-2.0.0.jar` (to verify that the file is included)
I was then able to run my Java program after I modify the `tess4j-2.0.0.jar` file. Below is my MacOS version.
