TROUBLESHOOTING TIPS:

1. Problems with dependencies installation
   Try to install them manually one by on with use of scripts in zcm2ros/dep/*_buils.sh.
   The sequence of installation you may see in zcm2ros/dep/build.sh

2. Problems with ROS packages
   In case of errors with "Missing network_interface/rviz/tf_conversions" and etc. try to install them by sudo apt-get install <your-ros-version>-<package>.
   For example for rviz installation with ROS Melodic run: sudo apt-get install ros-melodic-rviz

3. Problems with CV_LOAD_IMAGE_COLOR
   If there is a problem kind of "Invalid symbol: CV_LOAD_IMAGE_COLOR" or etc, you are probably trying to compile program againt opencv 3.0 (your opencv version installed is 3.0).
   In this case replace CV_LOAD_IMAGE_COLOR by cv::IMREAD_COLOR in zcm2ros/src/zcm2roc/src/converter.cpp

4. Problems with Java Virtual Machine
   In case when you have problems like:

   Unrecognized option: -Xincgc (or something else)
   Error: Could not create the Java Virtual Machine
   

   First run java -version. If your java version is defferent than 8, you need to switch its usage by:
   sudo update-alternatives --config java
   and than from the list choose v.8 (because it's used in the project)

   Further when you need different java version simply switch its usage
