how to use __as_b32 and __as_ptr_remote_dsmem in my own cuda code?

[hellboywyh]

I use__as_b32 and __as_ptr_remote_dsmem in my cuda code as follows:

and I have added the including as follow:
#include<__cuda/ptx/ptx_helper_functions.h>
and I compile it with the option -Icccl/libcudacxx/libcxx/include
then I got the following error:

Is there anyone can help to solve this problem?

The ptx_helper_functions header is inside an internal header with a reserved identifier. You should never include them on your own.

Rather than that you should include the respective parent header, in this case <cuda/ptx>

Oh, is it possible that you are on windows and it has issues with path depth / length?

Please see whether it helps if you move cccl to a different folder like C:/src/cccl
