Hi,

I am getting an error with Tess4j when I run it in a Windows Server 2008 R2 64 bit (tess4j-4.3.0).

Exception in thread "main" java.lang.UnsatisfiedLinkError:

at com.sun.jna.Native.open(Native Method)

at com.sun.jna.Native.open(Native.java:1759)

at com.sun.jna.NativeLibrary.loadLibrary(NativeLibrary.java:260)

at net.sourceforge.tess4j.Tesseract.init(Tesseract.java:426)

at net.sourceforge.tess4j.Tesseract.getWords(Tesseract.java:693)

I am using jdk1.8 64 bit

I don't have the error in a Windows 8.1 Enterprise 64 bit

I have tried using dependecy walker to figure out which dlls I was missing. I tried adding a few (dcomp,vcruntime140,msvcp140 and a few more), but no luck.

Can anyone help?

Make sure the Tesseract DLL is in the system PATH or java.library.path...?

Hi Aaron,

I already tried that, but no luck.

I can load liblept1760, but not tesseract400, using Native.loadLibrary("libtesseract400", com.sun.jna.Library.class)

I believe I have some conflict, but don't know which.

Can you try with version 4.3.1 or the latest version 4.4.1?

It worked with 4.4.1. Thanks a lot!
