Default to static linking of libcudart by bdice · Pull Request #1627 · rapidsai/cuvs

bdice · 2025-12-09T17:11:27Z

Summary

Enable static linking of libcudart by default (CUDA_STATIC_RUNTIME=ON)
Remove cuda-cudart from conda recipe run requirements (no longer needed when statically linked)

This is part of a RAPIDS-wide effort to switch to static CUDA runtime linking. See rapidsai/build-planning#235 for tracking.

Changes

cpp/CMakeLists.txt: Change CUDA_STATIC_RUNTIME default from OFF to ON
conda/recipes/cuvs/recipe.yaml: Remove cuda-cudart from run deps
conda/recipes/libcuvs/recipe.yaml: Remove cuda-cudart from run deps (4 outputs)

Note: Python builds already use CUDA_STATIC_RUNTIME=ON (set in python/libcuvs/CMakeLists.txt).

- Remove CUDA_STATIC_RUNTIME option from cpp/CMakeLists.txt - Always use static CUDA runtime in rapids_cuda_init_runtime - Update get_cutlass.cmake and get_faiss.cmake to always use static - Remove CUDA_STATIC_RUNTIME from python/libcuvs/CMakeLists.txt - Remove CUDA_STATIC_RUNTIME from docs - Remove cuda-cudart from run requirements in conda recipes

Missing changes to ci/build_go.sh and docs/source/build.rst to remove -lcudart
Missing changes to rust/cuvs-sys/build.rs to drop cargo:rustc-link-lib=dylib=cudart
examples/go/README.md Needs updating

This reverts commit ed1c778.

libcuvs.so is still getting CUDA::cudart rather than CUDA::cudart_static due to a leak from rmm::rmm. Relevant excerpt from lib/cmake/rmm/rmm-targets.cmake:

# Create imported target rmm::rmm
add_library(rmm::rmm SHARED IMPORTED)

set_target_properties(rmm::rmm PROPERTIES
  INTERFACE_INCLUDE_DIRECTORIES "${_IMPORT_PREFIX}/include"
  INTERFACE_LINK_LIBRARIES "CUDA::cudart;CCCL::CCCL;dl;nvtx3::nvtx3-cpp;rapids_logger::rapids_logger"
  INTERFACE_POSITION_INDEPENDENT_CODE "ON"
)

This reverts commit 067efea.
