Building the software

./do-update-makerpm.sh -S ${PWD} -w ${PWD}/tmp

To build with vnic, use the command
Note: at this time, this is only operational on RHEL 7.5

./do-update-makerpm.sh -V -S ${PWD} -w ${PWD}/tmp

To build the CUDA version

./do-update-makerpm.sh -G -S ${PWD} -w ${PWD}/tmp

Before running the CUDA builds, make sure the CUDA packages are installed
on your machine. Also export the following directories

SLES 12.2

export NVIDIA_GPU_DIRECT=${NVIDIA_GPU_DIRECT:-/usr/src/kernel-modules/nvidia-367.48-default}

SLES 12.3

export NVIDIA_GPU_DIRECT=${NVIDIA_GPU_DIRECT:-/opt/nvidia/NVIDIA-Linux-x86_64-384.66-diagnostic/kernel}

RHEL 7.3 and 7.4 and 7.5

For CUDA version 8.0
export NVIDIA_GPU_DIRECT=${NVIDIA_GPU_DIRECT:-/usr/src/nvidia-367.48}

For CUDA version 9.1
export NVIDIA_GPU_DIRECT=${NVIDIA_GPU_DIRECT:-/usr/src/nvidia-387.26}

Make sure you clear out the tmp directory before rebuilding

Once the SRC RPM is created, build the binary RPM from ./tmp/rpmbuild directory execute the following command

rpmbuild --rebuild --define "_topdir $(pwd)" --nodeps SRPMS/*.src.rpm
