Undefined reference to `nvtxstartrange_'

Hi, I ran into the following error that linker not able to find nvtx functions. I included the path to cuda/lib64 and -lnvToolsExt. But still I got the following error. Did I miss something?

Hi y.juntao,

I’m assuming you’re using the NVTX module that ships with the compilers? If so, try linking against our NVTX wrapper library, “-lnvhpcwrapnvtx”, rather than -lnvToolsExt directly.

Thanks Mat, problem solved.
