[Openmp-dev] nvlink fatal : Could not open input file '/tmp/get_mem-decc5d.cubin'

[Itaru Kitayama via Openmp-dev]

Thank you, Alexey for building the app. In my environment, I stick to
CUDA Toolkt 10.1, as 8 seems
require older GCC releases, but higher than CentOS 7's default 4.8.
Anyway, in summary
by configuring NEST with yours, builds went well without an issue.
Both -O0 and -O3 works.

Below is mine
cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=clang
-DCMAKE_CXX_COMPILER=clang++ -DCMAKE_CXX_FLAGS="-fopenmp
-fopenmp-targets=nvptx64"
-DCMAKE_INSTALL_PREFIX=$HOME/opt/nest-clang-offloading
-Dwith-python=OFF ~/projects/nest-simulator
