Hello AI world build failing at cmake

Robotics & Edge Computing Jetson Systems Jetson Orin Nano

Hello,

I am running on a Jetson Orin Nano Developer Lit and trying to build Hello AI World from source

I have a fatal “Error 2” in build while building from source after cmake ../ & make -j$(nproc)

usr/bin/ld: cannot find -lnpymath: No such file or directory
collect2: error: ld returned 1 exit status
make[2]: *** [python/bindings/python3.10/CMakeFiles/jetson-inference-python-310.dir/build.make:239: aarch64/lib/python3.10/jetson_inference/python.so] Error 1
make[1]: *** [CMakeFiles/Makefile2:744: python/bindings/python3.10/CMakeFiles/jetson-inference-python-310.dir/all] Error 2
make: *** [Makefile:136: all] Error 2

My

output.log.make_nproc.txt (81.8 KB)

Jetpack:

Version: 6.2.1+b38

R36 (release), REVISION: 4.7

Docker:

Docker version 29.1.4

Ubuntu:

22.04.5 LTS (Jammy Jellyfish)

(seems this is fixed for the Jetson Orin Nano)

Having tried several patches from and also cloning R36.3.0 the error is persistent

Hi,

Do you mean jetson-inference below?

If yes, the sample is deprecated.
If you want to build the tutorial, please set up your environment with JetPack 6.0.

For the latest environment, please try our new tutorial instead:

Thanks.
