I'm using the following configuration: CUDA 11.4, CMake 3.21.3, Visual Studio 16.11.5, Windows 10.
I've used CMake to successfully generate a VS2019 solution. Here's the CMakeLists.txt file in its entirety (also found here):
cmake_minimum_required(VERSION 3.8 FATAL_ERROR)
project(cmake_and_cuda LANGUAGES CXX CUDA)
include(CTest)
add_library(particles STATIC
randomize.cpp
randomize.h
particle.cu
particle.h
v3.cu
v3.h
)
# Request that particles be built with -std=c++11
# As this is a public compile feature anything that links to particles
# will also build with -std=c++11
target_compile_features(particles PUBLIC cxx_std_11)
# We need to explicitly state that we need all CUDA files in the particle
# library to be built with -dc as the member functions could be called by
# other libraries and executables
set_target_properties( particles
PROPERTIES CUDA_SEPARABLE_COMPILATION ON
)
if(BUILD_TESTING)
add_executable(particle_test test.cu)
set_target_properties(particle_test PROPERTIES CUDA_SEPARABLE_COMPILATION ON)
target_link_libraries(particle_test PRIVATE particles)
add_test(NAME particles_10k COMMAND particle_test 10000 )
add_test(NAME particles_256k COMMAND particle_test 256000 )
if(APPLE)
# We need to add the default path to the driver (libcuda.dylib) as an rpath,
# so that the static cuda runtime can find it at runtime.
set_property(TARGET particle_test PROPERTY BUILD_RPATH ${CMAKE_CUDA_IMPLICIT_LINK_DIRECTORIES})
endif()
endif()
When I try to build the solution, it fails. Looking at the output, I get the following error: nvcc fatal : A single input file is required for a non-link phase when an outputfile is specified. This is one of the nvcc commands it tried to run:
"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.4\bin\nvcc.exe"
-gencode=arch=compute_52,code=\"compute_52,compute_52\"
-gencode=arch=compute_52,code=\"sm_52,compute_52\"

-Xcompiler "/EHsc /W3 /nologo /Od /Fd"C:\Users\firstname lastname\Documents\Github\code-samples\posts\cmake\build\Debug\particles.pdb" /FS /Zi /RTC1 /MDd /GR"
-o particles.dir\Debug\particle.obj
"C:\Users\firstname lastname\Documents\Github\code-samples\posts\cmake\particle.cu"
I can't quite tell, but I think it's having a hard time with the nested quotes in the second -Xcompiler option.
Is there anything wrong with the CMakeLists.txt file? Does this nvcc command look right? Why does nvcc think I'm trying to give it multiple input files?
