isaac_ros_nitros Build failure #32

Closed sandeepdutta closed 10 months ago

sandeepdutta commented 10 months ago

Hello,

I am having trouble buildng isaac_ros_nitros on Orin AGX platform. I am using the docker container from "jetson-containers". I have installed negotiated & other prerequisites . I have set "CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda/ . I have confirmed that libnvToolsExt.so exists in /usr/local/cuda/lib64. Not sure why I am getting the "file format" error for libgxf_core.so , seems to be a text file. I have attached the build log log.tgz Thank you Sandeep

I ran into this error: /usr/bin/ld: cannot find -lnvToolsExt many times when I had multiple CUDA versions installed on the machine. I would make sure you are only using 11.4 and that the 11.4 lib is in your LD_LIBRARY_PATH. This is in our Dockerfile: ENV LD_LIBRARY_PATH="/usr/local/cuda-11.4/targets/aarch64-linux/lib:${LD_LIBRARY_PATH}". Which docker container are you using specifically?

There were two separate issues . a) the LFS files in the repository isaac_ros_gxf git not get resolved (not sure why).

git lfs pull [fixed the issue) b) to resolve nvToolsExt I had to add "--cmake-args CUDA_TOOLCHAIN_ROOT_DIR=/usr/local/cuda" to the build command line.
