Add environment variables
sudo vim ~/.bashrc
Add the following at the end of the file.
# cuda
export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
Reload the .bashrc file
source ~/.bashrc
test
nvcc -V
Downgrade gcc
View the current gcc version
gcc -v
g++ -v
View the soft link under usr/bin
ls -l /usr/bin | grep gcc
ls -l /usr/bin | grep g++
Install gcc-5 and g++-5
sudo apt-get install gcc-5
sudo apt-get install g++-5
Modify soft link
cd /usr/bin
sudo ln -fs gcc-5* gcc
sudo ln -fs gcc-5* x86_64-linux-gnu-gcc
Check whether the modification is successful
gcc -v
