was trying to setup build for xmrig-cuda in ubunut, but getting error,

Help me resolve this issue.

Known bug with some combinations of CUDA Toolkit vs gcc 11

Use CUDA 11.7, or anything but gcc 11 with whichever CUDA Toolkit you currently have (probably 11.6.1 since that was the buggy one).

[johnwstanford]

I saw the same error with CUDA 11.5 and GCC 11 and fixed it by switching to GCC 9.
