it prints that libraries are missing. After two days searching and testing I found this: https://github.com/dusty-nv/jetson-video
I cloned it but the paths to the libraries are wrong… so again imagenet-camera.cpp prints errors. I cannot change 50 .h files to fix the paths inside. What should I do? Has anyone this problem? I am using a USB-webcam…
Hi plaketas1, from above it looks like you missed the cmake …/ command before running make. After deleting your jetson-inference directory, try running this:
$ git clone https://github.com/dusty-nv/jetson-inference
$ cd jetson-inference
$ git submodule update --init
$ mkdir build
$ cd build
$ cmake ../ # important to run this cmake command before make
$ make
$ sudo make install
If you get errors after following this, please post them here.
command I got around 200 pages of errors.
The last errors I got are depicted below:

At this point I think I would still recommend flashing a fresh SD card image, so we can establish a proper baseline here. Then follow these steps:
$ git clone https://github.com/dusty-nv/jetson-inference
$ cd jetson-inference
$ git submodule update --init
$ mkdir build
$ cd build
$ cmake ../ # important to run this cmake command before make
$ make
$ sudo make install
Try building the repo as-is first, before attempting to make the DEFAULT_CAMERA modification for your USB camera.
I flashed the last version of nvidia-ubuntu and finally the above commnands worked. It says to change the DEFAULT_CAMERA and use the /dev/video… I don’t use Logitech C920. How do I find what to put there? How do I find the type of my webcamera?
When I put DEFAULT_CAMERA to 0, I just save the .cpp file, I don’t do any compile again? Right? After running the commands 1 and 2 I get information about my camera, but when I execute:
Yes, after changing the DEFAULT_CAMERA, you need to compile again with make from your build/ directory. It shouldn’t need to re-build everything, just that file.
