Issue in running the resnet18 example.

[udit01]

I am using -C option instead of -c in the example guide: https://github.com/nnstreamer/nntrainer/tree/main/Applications/Resnet (Because I think it is a typo, already filed a PR regarding that). While build, it shows, that nnstreamer-test-devel dependency is not found. Although, I have installed that and nntrainer dependency both from the PPA. I am using ubuntu 22 , Some package dependency errors in libiniparser and opencv as well. Could you please recommend how to run the example? Thank you. Output on running the test.

Are you really running it on Ubuntu 22.04? Your log says:

C compiler for the host machine: cc (gcc 11.4.0 "cc (Ubuntu 11.4.0-2ubuntu1~18.04) 11.4.0")
C linker for the host machine: cc ld.bfd 2.38
C++ compiler for the host machine: c++ (gcc 11.4.0 "c++ (Ubuntu 11.4.0-2ubuntu1~18.04) 11.4.0")

If you are really running it on Ubuntu 22.04, you may need to clean up build tools, first. This also may imply that your apt source configuration is broken; you are installing packages from 22.04 and 18.04 mixed up, which may also imply that the PPA installation is mixed up (getting nnstreamer/nntrainer packages from 18.04 and 22.04). This will break inter-package dependencies, too.

As you can see in any successful PR's github-action log, it's being successfully built and tested in Ubuntu 22.04 and 20.04.

The error message can also be related to toolchain issues: the linux loader cannot find the symbol marked by toolchain.

Without further follow-up questions, I assume that this is resolved.
