CMAke无法通过NVIDA找到opencl sdk [英] CMAke can not find opencl sdk by NVIDA

问题描述

我刚刚安装了NVIDA CUDA工具包，用于在Windows 8.1上开发OpenCL应用程序.

I just installed NVIDA CUDA tool kit to use it for developing OpenCL application on windows 8.1.

我来解决一些问题:

1- FinedOpenCl.cmake无效，因为nvida工具包未设置opencl_dir.

1- FinedOpenCl.cmake doesn't work since opencl_dir is not set by nvida tool kit.

cmake文件为:

FIND_PACKAGE(OpenCL REQUIRED)
INCLUDE_DIRECTORIES(${OPENCL_INCLUDE_DIR})

和cmake错误是:

CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.1/Modules/FindPackageHandleStandardArgs.cmake:138 (message):
  Could NOT find OpenCL (missing: OPENCL_LIBRARY OPENCL_INCLUDE_DIR)
Call Stack (most recent call first):
  C:/Program Files (x86)/CMake/share/cmake-3.1/Modules/FindPackageHandleStandardArgs.cmake:374 (_FPHSA_FAILURE_MESSAGE)
  cmake/FindOpenCL.cmake:35 (find_package_handle_standard_args)
  CMakeLists.txt:5 (FIND_PACKAGE)

2- c ++接口没有cl.hpp.

2- There is no cl.hpp for c++ interface.

3-标头和库位于不同的目录中，因此很难在应用程序中使用它们.

3- Headers and libraries are on different directories and hence it is difficult to use them with application.

我的问题:

1-有什么我可以解决的吗?

1- Is there anything that I can do to solve them?

2-设置过程中是否有任何选项可以自动进行所需的设置.

2- Is there any option during setup that do the required setting automatically.

推荐答案

您可以使用其他-D选项运行cmake，例如:

You can run cmake with additional -D options, like:

cmake [some_your_options] -DOpenCL_LIBRARY=/cygdrive/c/cuda/lib -DOpenCL_INCLUDE_DIR=/cygdrive/c/cuda/include [some_your_other_options] .....

因此它将看到OpenCL，例如手动指定的路径.

So it will see OpenCL such manually specified paths.

为我的 CygWin64 提供的上一个示例，其中在C:\cygdrive文件夹中，我之前为所有必需的逻辑驱动器添加了mklink的几个符号链接，因此"c"链接至"C:\"， "d"链接到"D:\"，依此类推.

Upper example provided for my CygWin64, where in the folder C:\cygdrive I added several symbolic links by mklink for all needed logical drives before, so "c" links to "C:\", "d" links to "D:\" and so on.

我的NVidia CUDA安装路径确实是C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\，但是它不是很方便，因此我也在C:上命名为"cuda"的符号链接(mklink /D linkname "path")，所以/cygdrive/c/cuda/lib确实指向.

My NVidia CUDA install path is really C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\, but it is not very handy, so I also maked symlink (mklink /D linkname "path") on C: named "cuda", so /cygdrive/c/cuda/lib is really points to C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\lib.

在Windows上模拟Unix环境并在命令promt中进行编译非常棘手，是的.

Unix environment emulation on windows and compiling in command promt is very tricky, yes..
