Sorry for this question. I can already see that this has been asked several times. In fact, I think I found my answer at How to build CUDA 8 samples with gcc 5?
But I want to make sure that if I implement said solution (which I describe below) that this would not alter how other things work. To be honest, I am not entirely sure what the GNU is aside from what I get from googling it.
But to give some background, I have been trying to install the gpu support for xgboost on this site: https://xgboost.readthedocs.io/en/latest/build.html
The instructions are easy enough and are detailed below
git clone --recursive https://github.com/dmlc/xgboost
cd xgboost; make -j4
mkdir build
cd build
cmake .. -DUSE_CUDA=ON
make -j
When I get to
make -j
I get
mikedoho@RadMD:~/xgboost/build$ make -j

Now the solution I found at How to build CUDA 8 samples with gcc 5?
mentioned that I should do
sudo ln -s /usr/bin/gcc-5 /usr/local/cuda-8.0/bin/gcc
sudo ln -s /usr/bin/g++-5 /usr/local/cuda-8.0/bin/g++
Now I would imagine I would have to change gcc-5 and g++-5 to 6 and cuda-8.0 to cuda-9.1 for this to work for me but I want to make sure that this would not affect other things work like tensorflow (the original reason I have CUDA). I apologize it may not even affect that but I want to make sure.
