我尝试构建openCV for Java以在BeagleBoneBlack上运行它。我的问题是，当我交叉编译它为arm时，它仍然给我一个错误消息，说它在ARM位平台上加载IA 32位.so。我已尝试使用以下指南： http://www.ridgesolutions.ie/index.php/2013/05/24/building-cross-compiling-opencv-for-linux-arm/ 我遵循了这个指南： http://docs.opencv.org/doc/tutorials/introduction/desktop_java/java_dev_intro.html
我确实将生成的jar包含到Java项目中，并将openCV添加为本机库。另外，我将.so放入了baglebone black的jre / arm文件夹......
以下是完整的错误消息：
