Error looking up function 'TessTextRendererCreate' on Mac

[Hang Wen]

Hi, 

I got the following error when trying to initialize TessAPI1() on Mac:

Exception in thread "main" java.lang.UnsatisfiedLinkError: Error looking up function 'TessTextRendererCreate': dlsym(0x7fb8dad55ca0, TessTextRendererCreate): symbol not found
at com.sun.jna.Function.<init>(Function.java:208)

I've referred to this post, and made sure libtesseract.dylib  is in my system path. But I still got this error.

The TessAPI() works fine.

I have 3.02.02_3 and tess4j 2.0.1

Thank you for any ideas.

You'd need Tess4J 1.5, which is compatible with Tess 3.02.

Or other way around: TessTextRendererCreate is tesseract 3.04 (C-API) function, so you need to upgrade your tesseract library.
