我正在尝试生成具有以下特征的 docker 镜像
- SO --> ubuntu:18.04
- Java --> openjdk-11-jdk
- OpenCV --> 3.4.2版本
我能够成功生成图像，但 lib 文件夹中未生成 java342 文件，我收到此异常:java.library.path 中没有 opencv_java342
我使用以下命令作为入口点启动我的应用程序:
java -Djava.library.path=/var/lib/opencv-3.4.2/build/lib -jar Application.jar
日志输出
Constructor threw exception; nested exception is java.lang.UnsatisfiedLinkError: no opencv_java342 in java.library.path: [/var/lib/opencv-3.4.2/build/lib]

所以我想知道我是否在docker文件或openCV编译过程中遗漏了一些东西。
注意:如果我在 native 计算机中执行相同的进程，一切都会按预期工作
有什么建议吗？
最佳答案
将 libopencv_java342.so 文件从 /usr/local/lib 复制到 /usr/lib。
如果未生成 .so 文件，请尝试以下操作:
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr ..
关于java - Docker + Java + OpenCV，java.library.path中没有opencv_java342，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/58262682/
