[After Installing the TensorRT3.0 using debian installation method (https://developer.nvidia.com/nvidia-tensorrt3rc-download) for jetson tx2, I tried to compile the sampleUffMNIST.cpp file provided in “samples” folder, but i am getting an errors like Undefined References to createInferBuilder_INTERNAL()., ,undefined references to cudaFree and many such undefined references. Can u please help me regarding how can i solve this error

suradkarknipun,
Look like your cuda library is not existed - did you flash your Jetson TX2 using Jetpack 3.1 before installing TensorRT 3.0 RC? Jetpack 3.1 includes cuda 8.0.

My version looks like,

nvidia@tegra-ubuntu:~/Downloads/TensorRT-3.0.0/samples/sampleUffMNIST$ make -B
…/Makefile.config:6: CUDA_INSTALL_DIR variable is not specified, using /usr/local/cuda-8.0 by default, use CUDA_INSTALL_DIR=<cuda_directory> to change.
…/Makefile.config:9: CUDNN_INSTALL_DIR variable is not specified, using by default, use CUDNN_INSTALL_DIR=<cudnn_directory> to change.
