Trying to use dpkg-shlibdeps to determine dependencies for building a package, but it can't find dependencies of some multimedia libs

There doesn’t seem to be anything in /var/lib/dpkg for libnvbufsurface, libnvbufsurftransform or libv4l2 which would enable dpkg-shlibdeps to correctly identify all the dependencies needed by the executable.

hello oviano,

may I know what’s the real use-case, which package you would like to install?
please also share your environment setups, and also the L4T release version for reference,
i.e. $ cat /etc/nv_tegra_release

4

So I want to test out my application on a handful of Jetson devices, so on one of the devices I am using dpkg-deb to create a .deb package file, following some tutorials I found. The idea is I can then copy this to the other devices, run dpkg -I to install it and sudo apt install -f to install the dependencies.

So ideally the package file would also install include information about the required dependencies, so before building it I am running dpkg-shlibdeps on the binary as shown above. I can then paste the shlibs:Depends= line into the DEBIAN/control file prior to running dpkg-deb to create the package.

This mostly works with the exception of the three libraries shown the output above (libnvbufsurface, libnvbufsurftransform libv4l2) which are part of nvidia-l4t-multimedia and nvidia-l4t-multimedia-utils.

For these libraries it seems unable to calculate the dependencies of these libraries because it cannot find the associated symbols/shlist files that exists for the other libraries in /var/lib/dpkg/info.

I am asking if these files are available somewhere or have been accidentally missed out or something.

The results of cat /etc/nv_tegra_release is:

# R36 (release), REVISION: 2.0, GCID: 34956989, BOARD: generic, EABI: aarch64, DATE: Thu Nov 30 19:03:58 UTC 2023
# KERNEL_VARIANT: oot
TARGET_USERSPACE_LIB_DIR=nvidia
TARGET_USERSPACE_LIB_DIR_PATH=usr/lib/aarch64-linux-gnu/nvidia

The device is a reComputer J401 Carrier Board with a Jetson Orin NX 8GB installed onto it.

It’s flashed with Ubuntu 22.04/JP6 DP.

hello oviano,

please refer to developer guide to customize your RootFS for confirmation. Root File System.

6

That page describes how to create a custom rootfs presumably for flashing to the other devices.

That’s not what I require or was asking; I want to use the regular package install mechanism to install my test app on the pre-flashed devices.

Actually it basically works, I was just hoping that I could get the dependencies perfect, hence the Q.

hello oviano,

it’s from MMAPI package, which is available via APT server. (i.e. $ sudo apt install nvidia-l4t-jetson-multimedia-api) it has dependency of Jetpack release version (i.e. /etc/nv_tegra_release)

hence..
you should delivery deb package across two targets based-on the same JP release version.
