Run on Raspberry Pi prompting errors：java.lang.UnsatisfiedLinkError: no jniopenblas_nolapack in java.library.path: /usr/java/packages/lib:/lib:/usr/lib

[visionki]

I need to use JavaCV on my Raspberry Pi to take pictures, but my development environment is Windows.

The maven dependencies I introduced are：

        <dependency>
            <groupId>org.bytedeco</groupId>
            <artifactId>javacv-platform</artifactId>
            <version>1.5.8</version>
        </dependency>

The code snippet is as follows：

      try (FrameGrabber grabber = new OpenCVFrameGrabber(0);
           OpenCVFrameConverter.ToIplImage converter = new OpenCVFrameConverter.ToIplImage()){
         grabber.start();
         for (int i = 0; i < 10; i++) {
            Frame frame = grabber.grab();
            IplImage img = converter.convert(frame);
            opencv_imgcodecs.cvSaveImage(System.currentTimeMillis() + ".jpg", img);
         }
      } catch (FrameGrabber.Exception e) {
         throw new RuntimeException(e);
      }

This works fine on Windows, but when I use mvn package to package it and run it on Raspberry Pi, I get the java.lang.UnsatisfiedLinkError: no jniopenblas_nolapack in java.library.path: /usr/java/ packages/lib:/lib:/usr/lib error。

The full error is as follows：

Is there a dependent library missing?

[visionki]

I've tried maven direct mvn package packaging and platform specific packaging mvn -Djavacpp.platform=linux-armhf -Djavacpp.arch=arm package, but both have the same error

[saudet]

Please set the "org.bytedeco.javacpp.logger.debug" system property to "true" to get more information on the console.

[zBo1997]

what's your JDK version？

Please set the "org.bytedeco.javacpp.logger.debug" system property to "true" to get more information on the console.

The console I get after using System.setProperty("org.bytedeco.javacpp.logger.debug", "true"); is as follows：

I understand that JavaCV depends on the OpenCV library and FFmpeg, and I already have them installed on the Raspberry Pi, are there any dependencies I'm missing?

[visionki]

what's your JDK version？

I am using openjdk 17

# java -version
openjdk version "17.0.6" 2023-01-17
OpenJDK Runtime Environment Temurin-17.0.6+10 (build 17.0.6+10)
OpenJDK Server VM Temurin-17.0.6+10 (build 17.0.6+10, mixed mode, sharing)

[saudet]

What do you get if you call Loader.getPlatform()? And what are the values of the "os.arch" and "os.name" system properties?

[visionki]

What do you get if you call Loader.getPlatform()? And what are the values of the "os.arch" and "os.name" system properties?

The call to Loader.getPlatform() return linux-arm。

Here is the information about the system：

$ uname -a
Linux raspberrypi 6.1.19-v8+ #1637 SMP PREEMPT Tue Mar 14 11:11:47 GMT 2023 aarch64 GNU/Linux
$ cat /proc/version
Linux version 6.1.19-v8+ (dom@buildbot) (aarch64-linux-gnu-gcc-8 (Ubuntu/Linaro 8.4.0-3ubuntu1) 8.4.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #1637 SMP PREEMPT Tue Mar 14 11:11:47 GMT 2023

[saudet]

I mean, what do you get if you call System.getProperty("os.arch") and System.getProperty("os.name") in Java?

[visionki]

I mean, what do you get if you call System.getProperty("os.arch") and System.getProperty("os.name") in Java?

The printout reads：

os.arch: arm
os.name: Linux

[saudet]

What about "java.vm.name", "sun.arch.abi", and "sun.boot.library.path"?

[visionki]

What about "java.vm.name", "sun.arch.abi", and "sun.boot.library.path"?

java.vm.name: OpenJDK Server VM
sun.arch.abi: 
sun.boot.library.path: /usr/lib/jvm/temurin-17-jdk-armhf/lib

where sun.arch.abi does not print out the contents

[saudet]

Ah, ok, so you are using a 32-bit JDK. We'll need to update the hack from @vb216 that checks for "openjdk-armhf" in "sun.boot.library.path" to just "armhf", I guess. For now, you can work around that by setting the "org.bytedeco.javacpp.platform" system property to "linux-armhf".

[visionki]

@saudet Great! He is now working properly, thank you very much!

[zBo1997]

@visionki hey! Could I get your contact information?

[saudet]

Fix released with JavaCPP 1.5.9! Thanks for reporting

[highwayhu]

@visionki hi, I'm experiencing the same issue. My environment variable is

javacpp platform: linux-x86_64 os.arch: amd64 os.name: Linux sun.boot.library.path: /opt/taobao/install/ajdk-8_10_15_fp11-b50-dep/jre/lib/amd64 org.bytedeco.javacpp.platform: null

. Could you kindly advise on how to resolve this?

[saudet]

That sounds like something going awry with static initialization. Please try to call Loader.Detector.getPlatform() instead.

[manju22412]

There are few other openblas os related jars, like [openblas-0.3.26-1.5.10-linux-x86_64.jar, openblas-0.3.26-1.5.10-macosx-arm64.jar, openblas-0.3.26-1.5.10-macosx-x86_64.jar]. By adding above respective os jar along with normal openblas jar, will resolve the issue.
