Build issues on x86_64 about redtail HOT 6 CLOSED

It seems like you are running our Jetson install script (jetson_ros_install.sh) on your x64 machine directly. We have not tested this scenario and it's not supported - the script is intended to be used only with Jetson/JetPack. I can suggest 2 options:

1. Use our Docker image which has all the components required to run redtail. Once you build and run the container, you can set up the ROS nodes in any way you like, for example, run the controller node on your vehicle, while DNNs - on your laptop (from Docker).
2. Try fixing the script. When you do that, I strongly recommend doing so from a Docker container to avoid polluting your host system. You don't have to use our image, but you can use it as a starting point and skip the components you don't need (e.g. Gazebo etc).

Thank you for the suggestions. Either of those should work for me. The Docker image solution seems fast and easy, except that it appears to be a 6.21GB file, and unfortunately I'm limited by a slow rural internet connection.

For installing directly on my machine, it would help if you could suggest what dependencies are required to build the redtail ros nodes? ROS kinetic is installed and working. This machine was also used to install Jetpack on tx1 and tk1. Other than what the script installed, I built opencv2.4.13 from source after the script complained about wrong opencv version.

I tried manually building caffe_ros_node in the workspace setup by jetson_ros_install.sh

It appears from the output that it's a linker error, but I'm confused how to solve it. I do have qt5 on my machine. I.E. qgroundcontrol builds from source without any errors.

My guess would be OpenCV versions issue. caffe_ros by itself does not use any qt libraries so it is most likely coming from OpenCV. Having multiple versions of OpenCV is a pain (to put it mildly) so this where Docker might help. Another idea would be to build OpenCV without QT (and other redundant in this case components, like samples, tests etc) and see if it helps.
The main reason our code uses version 2.4.13 is that this is the version installed by JetPack so we wanted to avoid building OpenCV in our scripts.

I was able to build caffe_ros after rebuilding OpenCV 2.4.13 without QT. The docker image is still downloading...

However, now there is an issue building caffe_ros_tests that is giving me troubles.

tests.cpp:(.text+0x42): undefined reference to `cv::imread

Log is pasted below.

Searching suggested that missing opencv_imgcodecs could be the issue, but it seems to be on my system.
I have verified that opencv_imgcodecs.so is present on my LD_LIBRARY_PATH

It looks like it's the wrong version of libopencv_imgcodecs: in your output, it's 3.3, not 2.4.

Awesome, nice work Alexey! I was able to get caffe_ros_node running on my x86_64 laptop by building with your alexeyk/2.0 branch. Now I've got the tx1 running trailnet onboard the rover, and the yolo node running on my gtx1070 laptop.
