在现在发布的存档中，有多个项目层次结构。您在该问题中发布的实际错误是在基于cluutp的clutbb / cluster / bin目录中的clu项目的编译和链接期间发生的。

在此同一个目录下，有一个CMakeLists.txt文件。

在这个特定的CMakeLists.txt文件中，有以下部分：

  cuda_add_executable（clu clu.cpp）
 target_link_libraries（clu $ {CUDA_LIBRARY} $ {TBB_LIBRARY} $ {Boost_LIBRARIES} rt）
 target_link_libraries ）
 

尝试将上面的中间行修改为：

  target_link_libraries（clu $ {CUDA_LIBRARY} $ {TBB_LIBRARY} $ {Boost_LIBRARIES} rt cuda）
 

这应该修复链接器命令行中缺少的 -lcuda 。它可能仍然需要给它的路径 libcuda.so 在您的机器上，但它可能没有必要，这取决于您的机器环境设置。 p>

I'm trying to build a program that requires CUDA. To the CMake script I supply:

cmake -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda ..

CUDA is found and CMake runs normally:

staudt ~/workspace/clutbb/cluster/build $ cmake -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda ..                                                                                  
-- Found CUDA: /usr/local/cuda (found version "6.5") 
-- Found Intel TBB

But then the linker step fails:

The required library is at /usr/local/cuda/lib64/stubs/libcuda.so, but how can I point that out to cmake or make?

In the archive you have now posted, there are multiple project hierarchies. The actual error you have posted in the question is occurring during compile and linking of the clu project based on clu.cpp in the clutbb/cluster/bin directory.

In this same directory, there is a CMakeLists.txt file. This file governs this particular level of the project hierarchy.

In this particular CMakeLists.txt file, there is the following section:

cuda_add_executable(clu clu.cpp)
target_link_libraries(clu ${CUDA_LIBRARY} ${TBB_LIBRARY} ${Boost_LIBRARIES} rt)
target_link_libraries(clu cluster)

Try modifying the middle line above to:

target_link_libraries(clu ${CUDA_LIBRARY} ${TBB_LIBRARY} ${Boost_LIBRARIES} rt cuda)

This should fix the missing -lcuda in the linker command line. It may still be necessary to give it the path to libcuda.so on your machine, but it may not be necessary, depending on how your machine environment is set up.
