Make errors: Ignore?
make CUDA samples, builds fine, but there are many errors. though many examples run.
what step did I miss?
are some of these examples not available on TK1? 
WARNING - CUDA OpenMP Libraries are not found
This CUDA Sample cannot be built without libgomp libraries. This will be a dry-run of the Makefile. For more information on how to set up your environment to build and run this sample, please refer the CUDA Samples documentation and release notes
WARNING - No MPI compiler found.
CUDA Sample "simpleMPI" cannot be built without an MPI Compiler. This will be a dry-run of the Makefile. For more information on how to set up your environment to build and run this sample, please refer the CUDA Samples documentation and release notes
>>> WARNING - libcuda.so not found, CUDA Driver is not installed. Please re-install the driver. <<<
>>> WARNING - required GPU not available on this platform - waiving sample <<<
Some of the CUDA samples use other libraries such as OpenMP or MPI or OpenGL. If you want to compile those samples then you'll need to install those toolkits, otherwise you can just ignore those few samples and stick to the samples that are self-sufficient.
I am new to the Jetson and Parallel programming. I flashed the Jetson TK1 as per instructions on the official download page from Nvidia. My CUDA Samples work perfectly fine as well.
However as per the Installing CUDA Page on elinux, I ran the "nvcc -v" in the home directory on the Jetson. It resulted in:
nvcc fatal: No input files specified; use option --help for more information.
Does this mean that the programs were compiled on my PC (the host used while flashing the Jetson) and CUDA is not installed on the Jetson?
Kindly provide your inputs.
