You are attempting to use the GNU C++ compiler to compile CUDA code (the unrecognized flags are specific to nvcc). What specifically do you want to do and how did you modify the default config.mk?

[Adrian]

I just noticed that you reported the same thing two years ago. What is up with this?

I still cann’t pass. which linux version are you using. I use fedora 41, the gcc is version 14. so, it complain about ” it cann’t support gcc later than 12″

I am realy confused about it.

What do you mean? In the other thread you said that it works. Please share your config, the error you posted doesn’t make sense. In any case, it would be nice if you described your problem instead of just dumping an error message without context and comment.

The error message “it cann’t support gcc later than 12” is hopefully self explanatory.
