尝试从Odroid-U3上的源代码编译ROS Hydro时遇到问题。这是相关的错误：

<== Failed to process package 'opencv2':
Command '/home/odroid/ros_catkin_ws/install_isolated/env.sh make -j4 -l4' returned non-zero exit status 2
Reproduce this error by running:
==> cd /home/odroid/ros_catkin_ws/build_isolated/opencv2 && /home/odroid/ros_catkin_ws/install_isolated/env.sh make -j4 -l4
Command failed, exiting.
已经尝试按sudo apt-get install安装这些库，但没有区别。任何帮助都是极好的。谢谢！
