UnsatisfiedLinkError: The specified module could not be found

[nobleson]

I have gradually followed this document example, using netbeans. http://tess4j.sourceforge.net/tutorial/
My System configuration is as follow: Windows 7 64bit. JDK 1.8 Microsoft visual c++ 2015 86x already existed so i installed 2017 64bit also. I have also find and downloaded all the required jar files as you can see. commons-io-2.5.jar jai-imageio-core-1.3.1.jar jna-4.1.0.jar jul-to-slf4j-1.8.0-beta2.jar lept4j-1.10.0.jar logback-classic-1.1.3.jar logback-core-1.1.3.jar slf4j.jar tess4j-4.0.2.jar

I also added the testdata folder but i got this error

run: Exception in thread "main" java.lang.UnsatisfiedLinkError: The specified module could not be found.

The problem seems to have been fixed by compiling the DLL not using Enhanced Instruction Set.

This issue seems to be resolved after upgrading the dependent jars to latest versions. Attaching a screen shot of the jars used as i am not sure which has solved the issue(maybe the jna.jar version). Followed the tutorial @ http://tess4j.sourceforge.net/tutorial/.

Hi @nguyenq, Currently, we are using below Gradle dependencies. Some AWS EC2 instances are causing this issue. Which version of tess4j has a fix to support both AVX and non-AVX CPUs?

• compile group: 'org.bytedeco.javacpp-presets', name: 'leptonica', version: '1.77.0-1.4.4'
• compile group: 'org.bytedeco.javacpp-presets', name: 'leptonica', version: '1.77.0-1.4.4', classifier: 'windows-x86_64'
• compile group: 'org.bytedeco.javacpp-presets', name: 'tesseract', version: '4.0.0-1.4.4'
• compile group: 'org.bytedeco.javacpp-presets', name: 'tesseract', version: '4.0.0-1.4.4', classifier: 'windows-x86_64'

Issue resolved after install "VC++ 2017 redistributable package x64". Just to update.

Hello everybody. I am using Tess4j in Java SDK version 1.8.0_251 under Intellij Idea. I solved the UnsatisfiedLinkError... using the version 3.4.8 of Tess4j. You can find it online. Or if you want here is the link of the folder of jars I used : https://drive.google.com/file/d/1bAk9ioTHERX0_VMR0INw2I6QRD5iO3Rl/view?usp=sharing Hope it will help you

Hello Everyone, Seems this issue happen again in tess4j 4.5.1. And i checked my CPU, it should support AVX.Then i change to use tess4j 4.4.0 and it is ok.Thanks

[nguyenq]

@pengsili You have VC++ 2019 redistributable package x64 installed?

[amankumarmonga09]

I have tried multiple Tess4j versions (from 4.4.0 to 4.5.0) but ended with same error. Then finally I agreed to above comment of installing VC++ 2015-2019 and finally resolved the issue now.

I am reproducing the issue with tess4j 4.5.4 and lept4j 1.14.0, I have installed the latest VC C++ versions:

Please note that using tess4j 4.4.1 it works fine but I want to use the newer version

[nguyenq]

@mahmoud19901990 Try with lept4j-1.13.2 dependency.

Estoy presentando el mismo problema en la version >4.5.4 pero para windows server 2019 en mi local funciona bien

I had some of my clients experiencing this issue. because I ran from IDE, the files got extracted. The clients that used a packaged javafx exe, did not get the files extracted. I believe it has something to do with the method of how to get resources. The Some.class.getResourceAsStream("path") always works for me.
