What is the correct way to handle #include xxx.cuh file from a cuda kernel with the DPCT tool?

 

I have a single kernel.cu file that I a porting to sycl using DPCT that has a cuda include file, kernel.cuh.  I seem to be getting a correct port, except the kernal.dp.cpp file keeps the "#include kernel.cuh"  

 

I also seem to be having a problem with device constants such as 

__device__ __constant__ int d_foo;
__device__ __constant__ float d_bar;
 
these see to be ignored by DCPT

Hi,

Thanks for reaching out to us.

 

>>What is the correct way to handle #include xxx.cuh file from a cuda kernel with the DPCT tool?

 Header files which are located in same directory of source files are migratable when specified by --in-root.

 We can also use --extra-arg flag which is used to include header files explicitly.

 For more details you can refer below link:

>> problem with device constants

Please try above methods during migration of header files(.cuh), if the issue still persists please provide us a sample reproducer and steps you have followed to migrate.

 

Thanks & Regards

Noorjahan.
