From 1c60231ca546597ef8b80e7340c8991b06387cbf Mon Sep 17 00:00:00 2001 From: Brad King Date: Tue, 14 Feb 2017 10:34:10 -0500 Subject: CUDA: Link to standard system libraries when linking as CUDA On Windows with MSVC-like host compilers we must honor the standard libraries chosen by the `Platform/Windows-MSVC` module. Otherwise C code linked into the CUDA binary that expects to have these libraries available may not link. --- Modules/CMakeCUDAInformation.cmake | 6 ++++++ Modules/Platform/Windows-NVIDIA-CUDA.cmake | 2 ++ Tests/Cuda/WithC/main.c | 8 ++++++++ 3 files changed, 16 insertions(+) diff --git a/Modules/CMakeCUDAInformation.cmake b/Modules/CMakeCUDAInformation.cmake index 13b1789..1c48159 100644 --- a/Modules/CMakeCUDAInformation.cmake +++ b/Modules/CMakeCUDAInformation.cmake @@ -93,6 +93,12 @@ if(NOT CMAKE_NOT_USING_CONFIG_FLAGS) endif() +if(CMAKE_CUDA_STANDARD_LIBRARIES_INIT) + set(CMAKE_CUDA_STANDARD_LIBRARIES "${CMAKE_CUDA_STANDARD_LIBRARIES_INIT}" + CACHE STRING "Libraries linked by default with all CUDA applications.") + mark_as_advanced(CMAKE_CUDA_STANDARD_LIBRARIES) +endif() + include(CMakeCommonLanguageInclude) # now define the following rules: diff --git a/Modules/Platform/Windows-NVIDIA-CUDA.cmake b/Modules/Platform/Windows-NVIDIA-CUDA.cmake index 809ee06..eda41e0 100644 --- a/Modules/Platform/Windows-NVIDIA-CUDA.cmake +++ b/Modules/Platform/Windows-NVIDIA-CUDA.cmake @@ -40,3 +40,5 @@ string(APPEND CMAKE_CUDA_FLAGS_DEBUG_INIT " -Xcompiler=-MDd,-Zi,-RTC1") string(APPEND CMAKE_CUDA_FLAGS_RELEASE_INIT " -Xcompiler=-MD") string(APPEND CMAKE_CUDA_FLAGS_RELWITHDEBINFO_INIT " -Xcompiler=-MD") string(APPEND CMAKE_CUDA_FLAGS_MINSIZEREL_INIT " -Xcompiler=-MD") + +set(CMAKE_CUDA_STANDARD_LIBRARIES_INIT "${CMAKE_C_STANDARD_LIBRARIES_INIT}") diff --git a/Tests/Cuda/WithC/main.c b/Tests/Cuda/WithC/main.c index f9101a7..cb5fddc 100644 --- a/Tests/Cuda/WithC/main.c +++ b/Tests/Cuda/WithC/main.c @@ -1,6 +1,14 @@ extern int use_cuda(void); +#ifdef _WIN32 +#include +#endif + int main() { +#ifdef _WIN32 + /* Use an API that requires CMake's "standard" C libraries. */ + GetOpenFileName(NULL); +#endif return use_cuda(); } -- cgit v0.12
