[Openmp-dev] ptxas fatal : Cannot take address of function '__pthread_key_create'

[Itaru Kitayama via Openmp-dev]

Hi,
I am trying to build an application that can do OpenMP offloading on a
POWER8 + P100 system using the latest LLVM/Clang toolchain (openmp
is too the latest).

The build error is:
[  3%] Building CXX object sli/CMakeFiles/sli_lib.dir/arraydatum.cc.o

The CUDA toolkit is 9.2.88, is it possible the error is fixed in the
latest toolkit?

Thanks,
Itaru.
