clGetPlatformIDs调用中出现错误-1001 !!!

Error -1001 in clGetPlatformIDs Call !!!

我该如何解决?这是否意味着我的nvidia卡无法被检测到?我正在运行Ubuntu 10.10，并且X服务器可以与nvidia驱动程序一起正常使用.

How can I fix it? Does it mean my nvidia cards cannot be detected? I am running Ubuntu 10.10 and X server works properly with nvidia driver.

我很确定问题与文件权限无关，因为它也不适用于sudo.

I am pretty sure the problem is not related to file permissions as it doesn't work with sudo either.

推荐答案

对于我来说，我已经通过安装ubuntu中提供的 nvidia-modprobe 软件包(utopic/multiverse)解决了该问题.并且驱动程序本身(v346)是从
https://launchpad.net/安装的〜mamarley/+ archive/ubuntu/nvidia

具体来说，我已经安装了nvidia-opencl-icd-346，nvidia-libopencl1-346，nvidia-346-uvm，nvidia-346和libcuda1-346.不确定OpenCL是否全部需要它们.

In my case I have solved it by installing nvidia-modprobe package available in ubuntu (utopic/multiverse). And the driver itself (v346) was installed from
https://launchpad.net/~mamarley/+archive/ubuntu/nvidia

Concretely, I have installed nvidia-opencl-icd-346, nvidia-libopencl1-346, nvidia-346-uvm, nvidia-346 and libcuda1-346. Not sure if they are all needed for OpenCL.
