linux编译运行jar包崩溃

• OS info

❯ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 22.04.3 LTS Release: 22.04 Codename: jammy

• JDK

❯ java -version java version "1.8.0_351" Java(TM) SE Runtime Environment (build 1.8.0_351-b10) Java HotSpot(TM) 64-Bit Server VM (build 25.351-b10, mixed mode)

• 流程

  1. 使用README提供的命令进行构建

  mkdir target\jfx\app
  cp -r models target\jfx\app
  mvn jfx:native -DskipTests -f pom.xml
  

  2. 编译完成后目录如下(省略部分路径)

  .
  ├── app.properties
  ├── docs
  ├── LICENSE
  ├── models
  ├── package.json
  ├── pom.xml
  ├── src
  ├── target
  │   ├── jfx
  │   │   ├── app
  │   │   └── native
  │   └── tools-ocr-2.2.9.jar
  └── targetjfxapp
  

  3. 进入路径target/jfx/native/treehole/app/

  cd target/jfx/native/treehole/app/
  
  # 使用提供的命令下载模型
  wget https://github.com/litongjava/tools-ocr/releases/download/model-ppocr-v4/ch_PP-OCRv4_det_infer-onnx.zip
  wget https://github.com/litongjava/tools-ocr/releases/download/model-ppocr-v4/ch_PP-OCRv4_rec_infer-onnx.zip
  mkdir -p models/ch_PP-OCRv4_det_infer
  mkdir -p models/ch_PP-OCRv4_rec_infer
  unzip ch_PP-OCRv4_det_infer-onnx.zip -d models/ch_PP-OCRv4_det_infer
  unzip ch_PP-OCRv4_rec_infer-onnx.zip -d models/ch_PP-OCRv4_rec_infer
  

  4. 当前的目录结构

  ❯ tree -L 2

5. 运行tools-ocr-2.2.9-jfx.jar

Java运行输出

❯ java -jar tools-ocr-2.2.9-jfx.jar

6. 日志hs_err_pid474539.log 内容 logs

我的操作有哪一步存在问题吗？任何指导都非常感谢！

1.请使用最版本测试一下 2.使用这个文件中的docker镜像 https://github.com/AnyListen/tools-ocr/blob/master/.github/workflows/build.yml

TL;DR: 已成功解决，为上游代码问题，希望作者更新代码。此外，在使用中发现一个截图偏移的问题。

存在的问题

1. 新的代码中使用了模型ONNX_PPOCR_V4_SERVER，但是上游项目RapidOcr-Java回滚了该更新 https://github.com/MyMonsterCat/RapidOcr-Java/issues/46 基于该issue重新编译rapidocr-onnx-models-1.2.2.jar，rapidocr-common-0.0.7.jar ps: 手动编译后不需要按照build.yml中下载模型文件到指定路径

2. 在手动编译jar包后依旧出现core dump 怀疑为上游jnativehook的问题 https://github.com/kwhat/jnativehook/issues/442 怀疑为版本问题，尝试使用不同版本 在更换版本为2.0.2时可以正常运行，并且，在全部共4个版本中仅有2.0.2版本编译出的可以正常运行

新发现的问题

在使用截图ocr时截图的框和实际内容不匹配，存在垂直下移的问题，猜测为全局缩放率导致的，
