`blt_hip_smoke` does not compile

[gzagaris]

Hello,

I am trying to compile with HIP and it seems that CMake attempts to compile the blt_hip_smoke test using the host-compiler.

My host-config looks like this:

#---------------------------------------------------------------------------------------------------
# Compiler settings
#---------------------------------------------------------------------------------------------------
set(CMAKE_C_COMPILER "/opt/cray/pe/gcc/12.2.0/snos/bin/gcc" CACHE PATH "Path to the C compiler." )
set(CMAKE_CXX_COMPILER "/opt/cray/pe/gcc/12.2.0/snos/bin/g++" CACHE PATH "Path to the C++ compiler." )

...

#---------------------------------------------------------------------------------------------------
# ROCM / HIP 
#---------------------------------------------------------------------------------------------------
set(ENABLE_HIP ON CACHE BOOL "")
set(ROCM_ROOT_DIR "/opt/rocm-5.7.0" CACHE PATH "")
set(HIP_ROOT_DIR "${ROCM_ROOT_DIR}/hip" CACHE PATH "")
set(HIP_CXX_COMPILER "${HIP_ROOT_DIR}/bin/hipcc" CACHE PATH "")
set(CMAKE_HIP_COMPILER "${ROCM_ROOT_DIR}/llvm/bin/clang++" CACHE FILEPATH "")

set(CMAKE_HIP_ARCHITECTURES "gfx90a" CACHE STRING "")
set(AMDGPU_TARGETS "gfx90a" CACHE STRING "")
set(GPU_TARGETS "gfx90a" CACHE STRING "")

I configure with CMake successfully, but, I see the following warnings:

-- Creating BLT HIP targets...

When building, e.g., with make -j, or just make make blt_hip_smoke/fast

I get the following error:

Building CXX object blt/tests/smoke/CMakeFiles/blt_hip_smoke.dir/blt_hip_smoke.cpp.o
g++: error: unrecognized command-line option '--rocm-path=/opt/rocm-5.7.0'

Any ideas? Am I missing any flags?

I tried this with blt v0.5.3 and the latest v0.6.2.

Thank you for all your help.

Unfortunately we are still on the original way to handle HIP which requires you to have your main compiler be the HIP compiler. See example here:

https://github.com/LLNL/blt/blob/develop/host-configs/llnl/toss_4_x86_64_ib_cray/clang%4016.0.0_hip.cmake

It is on our shortlist to fix.

Ugh...bummer, thanks @white238 !
