anyone know how to fix this error?

[saudet]

Please try again with version 1.5.10

[heshanthenura]

Ill try and tell you.

[saudet]

Please follow the instructions at https://github.com/bytedeco/javacpp-presets/wiki/Debugging-UnsatisfiedLinkError-on-Windows

[heshanthenura]

Thank you, I'll try.

[codespearhead]

Did it work? If so, can you close this issue?

[steeveen]

I met the same problem and searching for help……

[codespearhead]

Can you provide us with an MRE?

[steeveen]

Just Call ‘Loader.load(opencv_java.class)’ under RHEL-7, Java 8 ,SpringBoot 2.7.2

[steeveen]

with the dependency of javacv-platform 1.5.10, opencv-platform 1.5.10 , openblas-platform 1.5.10

[codespearhead]

It's worth noting that Spring Boot 2.7 no longer has OSS support.

I just tried it with my current setup and everything worked as expected (Spring Boot 3.2.4, OpenJDK Temurin-17.0.10+7).

1. Create a Spring Boot project:

mkdir mre &&
cd mre &&
curl https://start.spring.io/starter.tgz -d dependencies=web,devtools -d type=maven-project | tar -xzvf -

2. Add JavaCV to it:

<dependency>
    <groupId>org.bytedeco</groupId>
    <artifactId>javacv-platform</artifactId>
    <version>1.5.10</version>
</dependency>

3. Create an endpoint that invokes Loader.load(opencv_java.class):

package com.example.demo;

import org.bytedeco.javacpp.Loader;
import org.bytedeco.opencv.opencv_java;
import org.bytedeco.opencv.global.opencv_core;
import org.bytedeco.opencv.opencv_core.Mat;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class Demo {

    @GetMapping
    public String doGet(){
        Loader.load(opencv_java.class);
        Mat mat = Mat.eye(3, 3, opencv_core.CV_8UC1).asMat();
        return "mat = " + mat.toString() + "\n";
    }

}

4. Call the endpoint:

curl localhost:8080
# mat = org.bytedeco.opencv.opencv_core.Mat[width=3,height=3,depth=8,channels=1]

[steeveen]

Did you do your test on red hat OS? My code can run well on windows10 but meet problem just on redhat7.

[codespearhead]

I am not in a position to directly experiment with the suggested setup at this time.

For anyone who is though, try creating a Dockerfile in the root directory of the MRE with the following content:

FROM registry.access.redhat.com/ubi8/openjdk-17:1.19-1

WORKDIR /app
COPY . .

RUN mvn clean package -DskipTests
EXPOSE 8080

CMD ["java", "-jar", "target/app-0.0.1-SNAPSHOT.jar"]

Then run:

docker build -t demo:tag . &&
docker run --rm -it demo:tag

I have a further problem. I found that problem is caused by that there is no CXXABI 1.3.8 in my environment. Does anyone have any idea on this?

[codespearhead]

I haven't used this library long enough to be able to troubleshoot problems, but I noticed it works out of the box in WSL (Ubuntu), but not in Git Bash (Windows), so I have a feeling strange errors might occur if you don't have GCC globally available in your environment when installing the dependencies. I haven't tested that theory though.

[steeveen]

I got the libstdc.6.0.28.so, which can support CXXABI_1_3_8. I would have a try to replace libstdc.6.0.19.so with this file. I hope it can work.

I'm getting the original problem cited about the jniopenblas_nolapack not found. I've simply cloned the repo (version 1.5.10) and I'm trying to run the OpticalFlowDense.java example. Not having any luck find a solution on google. I'm using RHEL 9. Getting this error:

[saudet]

It looks like the libjniopenblas_nolapack.so isn't in your class path, you'll need to figure out why
