GPU Error

[zsz0811]

Hi,
when running AMReX on GPU, we get this error "/amrex/Src/Base/AMReX_GpuLaunchFunctsG.H line 885: named symbol not found"
any suggestions on what might be wrong?
thank you

You might need to set CUDA_ARCH explicitly. See for example, https://github.com/AMReX-Astro/Castro/pull/2715/files

Thank you so much. I worked.
