I am not a developer but I use CUDA for a few apps.
After sudo pacman -Syu I go this right under upgrading cuda:
- The default host compiler for nvcc is no longer configured using symlinks in
/opt/cuda/bin/ but by the $NVCC_CCBIN environment variable in
/etc/profile.d/cuda.sh. You need to source /etc/profile or restart your
session for it to be available in your environment. Additionally, you may
need to clear the build cache of your projects where the old path may have
been recorded.
- When you uninstall an old, unrequired version of GCC that was previously
required by cuda for the default host compiler ($NVCC_CCBIN), you may need
to source /etc/profile or restart your session. Additionally, you may need
to clear the build cache of your projects where the old path may be still
recorded.
Ummmm, any help what is this about?
