HIPCC environment variables

HIPCC environment variables#

This topic provides descriptions of the HIPCC environment variables. For more information about other ROCm environment variables, see HIP environment variables.

  • HIP_PLATFORM = amd or HIP_PLATFORM = nvidia

Note

If HIP_PLATFORM is not set, then hipcc will attempt to auto-detect based on if the nvcc tool is found.

Additional environment variable controls:

  • CUDA_PATH : Path to the CUDA SDK. The default is /usr/local/cuda. This is only used for NVIDIA platforms.

  • HIPCC_COMPILE_FLAGS_APPEND : Append extra flags as compilation options to hipcc.

  • HIPCC_LINK_FLAGS_APPEND : Append extra flags as linking options to hipcc.

  • HIPCC_VERBOSE : Outputs detailed information on subcommands executed during compilation.

    • HIPCC_VERBOSE = 1: Displays the command to clang++ or nvcc with all options (hipcc-cmd).

    • HIPCC_VERBOSE = 2: Displays all relevant environment variables and their values.

    • HIPCC_VERBOSE = 4: Displays only the arguments passed to the hipcc command (hipcc_args).

    • HIPCC_VERBOSE = 5: Displays both the command to clang++ or nvcc and hipcc arguments (hipcc-cmd and hipcc-args).

    • HIPCC_VERBOSE = 6: Displays all relevant environment variables and their values, along with the arguments to the hipcc command.

    • HIPCC_VERBOSE = 7: Displays all of the above: hipcc-cmd, hipcc-args, and environment variables.
