Thank you for response, and the correction! I’ve come across the linked GitHub repo and have in fact pulled models from it, as instructed further down the blog post, but I still wasn’t sure where to find the file “lpr_test_sample” even in the linked repo. Was it something that was supposed to show up during a build process? I suspect it could very well be the same app (or a more dated version) as “deepstream-lpr-app” which I should build. I’ll try that out when home, and if it seems to work out I will post again.
EDIT: It’s an error I’ve seen other people run into, but I ended up hitting when trying to build from the deepstream-lpr-app nested directory.
fatal error: gstnvdsmeta.h: No such file or directory
31 | # include “gstnvdsmeta.h”
(space added after “#” avoid automatic tag formatting)
I will be trying to resolve this myself, but if there are any things to look out for (especially with my more updated JetPack and DeepStream versions), then I’d always appreciate hearing about them.
EDIT 2: Tried out and attempted to interpret some solutions in this thread. I wasn’t sure which proposed solutions were applicable, and tried out a few with some modifications to version numbers where applicable, with no dice. If one of these should be expected to resolve the issue, however, then that’s fine.
I also consulted this thread but as a newcomer to Linux development I’m not quite sure what was meant in the proposed solution, what I should expect, or what the provided command does. However, I did observe that gstnvdsmeta.h was located in /opt/nvidia/deepstream/deepstream-7.0/sources/includes. Trying to run “make” with root permissions doesn’t change, so I can only assume that the Makefile isn’t reaching the right libraries at the moment.
The current Makefile is still identical to what is included in the repo: deepstream_lpr_app/deepstream-lpr-app.
