Thank you for the pull request. Which version of HIP is installed on your end? I don't see any compilation issue with 5.4.0

@zjin-lcf - Thanks for the review. hipcc is ChipStar (https://github.com/CHIP-SPV/chipStar.git) in this case.

I will not update the program because it can be compiled without error with HIPCC on AMD GPUs. Thanks.

Thanks for the update I will follow up on CHIP-SPV/chipStar#593 CHIP-SPV/chipStar#484

@zjin-lcf Please reopen this this PR as it is yet to be resolved by ChipStar team.

I found that egs-hip is also facing same issue,
