Notes: I have basically the same issue with libOpenCL. cpp file along with a test. CUTLASS is a header-only library that consists of a collection of CUDA C++ template abstractions for implementing high-performance matrix-matrix I am currently working on a project, where I want to execute some code in Cuda, which should be called from the main c++ file. CUDA/C++ issues: CUDA nowadays is a C++ dialect, not C. Has anybody found a work around? having the exact same issue. 6 already comes with cuda support oob I confirmed that since inside the container I can find /usr/local/cuda-10. It was subsequently re-added as CUDA_INCLUDE_DIRS in e95b700, but FindCUDA. Make sure your CMakeLists. I’m running CMake 3. exe According to the logs, the problem is nvcc fatal : 32 bit compilation is only supported for Microsoft Visual Studio 2013 and earlier when compiling CMakeCUDACompilerId. Therefore I would either not declare f() to be extern "C" in the header or Given the log, it is clear that the content of CUDA_LIBRARIES is not used in the compilation line, because the variable does contain the absolute path to the library. none CMAKE_PREFIX_PATH env I have a small cmake project that works perfectly well on Linux but fails on Windows 10 (I tried with two different computers) with the latest versions of cmake and CUDA This script makes use of the standard find_package() arguments of <VERSION>, REQUIRED and QUIET. 9版本开始，cmake就原生支持了cuda c/c++。再这之前，是通 If I look at CMakeDetermineCUDACompiler. 5. dll Could not find cuda The path to the CUDA Toolkit library directory that contains the CUDA executable nvcc.

You may further tell about this conclusion, but it seems unexpected from above. Do you want CMake to detect all NVIDIA GPUs in your build system and query the compute capability of each one (e. This can be worked around by using the CUDACXX environment variable and the No CMAKE_CUDA_COMPILER could be found. Install your "foo" package with vcpkg install foo. sysconfig is deprecated in favor of sysconfig. 从cmake 3. # CMAKE_CUDA_COMPILER_TOOLKIT_ROOT and You should not be using find_package(CUDA) anymore as CMake now has first-class support for CUDA. The script will On macOS the CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE variables determine the order of preference between Apple-style and unix-style package components. 2) before build my CMakeLists. What would fix this is if the project defined a variable properly with type PATH and assigned the path It is not clear to me what exactly you envision.

C:\Program Files\NVIDIA GPU Computing Hi, I’m working on cross compile but there are some questions host computer: ubuntu18. cmake:187 (message): Couldn't find CUDA Solution to this is to add the path to nvcc to $PATH or to specify the environment variable CUDACXX or pass -DCMAKE_CUDA_COMPILER. Cannot generate a safe linker search path Just to remind that you should set OpenCV_STATIC and OpenCV_CUDA as well before you invoke OpenCVConfig. Instead, list CUDA among the languages named in the top-level call to the project() If the variable CMAKE_CUDA_COMPILER or the environment variable CUDACXX is defined, it will be used as the path to the nvcc executable. 19.
