我正在尝试使用CMake编译使用C ++和CUDA的程序。 编译c ++文件的CMakeLists部分已经完成，我正在添加部件来编译CUDA文件。 我添加了源代码并且编译好了，但是当链接部分到来时它停止了。 这是CMakeLists.txt文件：

这是cmake输出：

我查了一下，显然当我使用-rdc = true标志编译CUDA程序时，我需要做一个额外的步骤来正确链接cuda库，但我不知道如何在cmake中这样做，我alredy尝试将“$ {CUDA_LIBRARY}”添加到与“target_link_libraries（main $ {ALL_LIBS}）”链接的“$ {ALL_LIBS}”，但这不起作用。

如果你看https://cmake.org/cmake/help/v3.0/module/FindCUDA.html，你会发现你的呼叫

find_package(CUDA REQUIRED)

定义CUDA_LIBRARIES，而非CUDA_LIBRARY。 我想改变这个可以解决你的问题。

答案 1 :(得分：0)

试试这个：

find_package(CUDA REQUIRED)
if(CUDA_FOUND)

#turn CUDA_SEPARABLE_COMPILATION on.
set(CUDA_SEPARABLE_COMPILATION ON)
include_directories(/usr/local/cuda/include)
add_definitions(-DUSE_GPU)
file(GLOB cu src/*.cu)

#The CUDA_NVCC_FLAGS variable is a list not a string.
list(APPEND CUDA_NVCC_FLAGS -gencode arch=compute_30,code=sm_30 -rdc=true -std=c+    +11)
cuda_add_library(cudanet STATIC ${cu})
target_link_libraries(cudanet ${CUDA_LIBRARIES})
target_link_libraries(darknet cudart cuda cublas curand)
message(STATUS "include & link cuda")
link_directories(/usr/local/cuda/lib64)
endif()
