hipcc is from ROCm. Please see the following message.

hipcc hipComplex.cc (chipStar/samples/hipComplex)

hipComplex.cc:8:5: error: use of overloaded operator '*=' is ambiguous (with operand types 'hipDoubleComplex' (aka 'HIP_vector_type<double, 2>') and 'hipDoubleComplex')
  y *= x;

Would you rewrite the operators as, for example, hipCmul(x,y) ?

@linehill Any idea why our sample would not compiler on rocm 5.4? Seems correct HP code to me.

It's most likely a bug in their headers. There is a same issue but for hipFloatComplex instead here: https://github.com/ROCm-Developer-Tools/HIP/issues/2797.

@Kerilk @linehill Thanks.
