在Cygwin中配置OpenCL？ [英] Configure OpenCL under Cygwin?

问题描述

如何在Cygwin下安装OpenCL驱动程序？

例如，linux下的OpenCL通常会检查/ etc / OpenCL / vendors列表中是否有ICD驱动程序在Linux上，nvidia.icd引用了libnvidia-opencl.so.1），但由于Cygwin没有任何Nvidia或OpenCL包，我假设我必须手动设置链接。

我有Windows Nvidia CUDA开发套件安装在同一台机器上，但不清楚这些文件是否应该是链接到的文件。

[注意，我已经构建了来自coprthr的OpenCL加载器实现libopencl.a，所以部分完成 - 它只是想出如何引用ICD]

• 确保OpenCL标题位于包含路径上。您可以在此处下载。


• 链接到

要运行程序，需要找到动态OpenCL库DLL。 NVidia驱动程序通常安装在C：\Windows \System32。

这对我有用。

How can I install OpenCL drivers under Cygwin?

For example, OpenCL under linux normally checks the /etc/OpenCL/vendors list for links to ICD drivers (e.g. on Linux, nvidia.icd references libnvidia-opencl.so.1), but since Cygwin doesn't have any Nvidia or OpenCL package, I'm assuming I'll have to set the links up manually.

I do have the Windows Nvidia CUDA dev kit installed on the same machine, but it's not obvious whether one of those files should be the one to link to.

[Note that I've already built the OpenCL loader implementation libopencl.a from coprthr, so that part is done - it's just figuring out how to reference the ICD]

解决方案

To compile a C/C++ OpenCL program on Windows using Cygwin or MinGW you need to:

• Make sure the OpenCL headers are on the include path. You can download them here.
• Link against a static OpenCL library (libopencl.a), which you already have.

To run the program, it needs to find the dynamic OpenCL library DLL. The NVidia driver usually installs it at C:\Windows\System32.

This works for me.
