Hello, friend!
You can use the following method to solve "unrecognized command line option '-fstack-protector-strong" error.
1. Run the following commands to modify kernel makefile configuration items:
cd /usr/src/kernels/$(uname -r)/include/config
sed -i 's/CONFIG_CC_STACKPROTECTOR_STRONG=y/CONFIG_CC_STACKPROTECTOR_REGULAR=y/' auto.conf
2. Run the NVDIA installation script again.
bash /opt/NVIDIA-Linux-x86_64-375.66.run
Hope this helps!
