-----------------------------------
Summary: ArrowCUDA erroneously links to CUDA Runtime while only
using Driver API
Key: ARROW-12300
URL: https://issues.apache.org/jira/browse/ARROW-12300
Project: Apache Arrow
Issue Type: Bug
Components: GPU, Packaging
Affects Versions: 3.0.0
Reporter: Keith Kraus
As far as I can tell the Arrow GPU code only uses the CUDA driver API, but the
CMake links it to the CUDA Runtime:
https://github.com/apache/arrow/blob/apache-arrow-3.0.0/cpp/src/arrow/gpu/CMakeLists.txt#L39
({{${CUDA_LIBRARIES}}} is defined via the CMake {{FindCUDA}} module here:
https://cmake.org/cmake/help/latest/module/FindCUDA.html#result-variables)
By default the static library for the CUDA Runtime will be used and things will
get statically linked inside of the Arrow GPU library unnecessarily.
Additionally, this can cause issues related to CUDA initialization as shown
here: https://github.com/rapidsai/cudf/issues/7600
