Cuda help on Ubuntu 16.04.

[mgillr]

As far as I can see I am running cuda 11.2 however when I cmake I get a compile error:

CMake Error at /usr/share/cmake-3.5/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
Could NOT find CUDA: Found unsuitable version "7.5", but required is at
least "8.0" (found /usr)

When I check the system I get

nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2015 NVIDIA Corporation
Built on Tue_Aug_11_14:27:32_CDT_2015
Cuda compilation tools, release 7.5, V7.5.17

But then

nvidia-smi

I am confused as nvcc --version shows 7.5 and nvidia-smi shows 11.2

How can I correct this

Get the latest at https://github.com/xmrig/xmrig/releases and for nvidia cards you also need the CUDA plugin from https://github.com/xmrig/xmrig-cuda.You have to compile the CUDA plugin yourself.put the xmrig-cuda.so in the same directory as where you put xmrig. Make sure you have the latest driver and nvidia-cuda-toolkit, yours is to old, installed from the (backport) repository.
Any questions abt xmrig should be asked https://github.com/xmrig/xmrig.
xmrig-nvidia is outdated and as far as I know abandoned.

For compiling I use the following in a script:
`
#!/bin/bash

#set -x
#no need for the following packages
#libhwloc-plugins libhwloc-contrib-plugins

echo
echo 'Now it'''s time to get a coffee, tea or any other beverage'
echo 'as it will take a while to finish compiling depending on'
echo 'how fast your system is (just over 6 mins. i7-7700HQ 16GB RAM'
echo 'or just over 4 mins. 5800x 32GB RAM.'
echo 'Ignore the warnings generated.'
echo 'When finished copy or move libxmrig-cuda.so to the'
echo 'directory where xmrig miner is installed.'
echo

read -p 'Press any key to continue'

#sudo apt-get install nvidia-cuda-toolkit

git -C /media/Public/github clone https://github.com/xmrig/xmrig-cuda.git

mkdir $HOME/github/xmrig-cuda/build && cd $HOME/github/xmrig-cuda/build

cmake /media/Public/github/xmrig-cuda -DCUDA_TOOLKIT_ROOT_DIR=/usr/lib/nvidia-cuda-toolkit

make -j$(nproc)

echo
echo 'IT'''S FINISHED, HURRAY!!'
`
Change it to any directory you want.
