在Ubuntu中设置OpenCL [英] Setting up OpenCL in Ubuntu

问题描述

嘿。我试图在Ubuntu中编译我的OpenCL项目。我有Core i5和AMD HD 5660兼容。


当我执行以下代码时

Hey. I trying to get my OpenCL project compile in Ubuntu. I have a Core i5 and AMD HD 5660 which are both compatible.

when I execute the following code

cl_int status;
// Retrieve the number of platforms
cl_uint numPlatforms = 0;
status = clGetPlatformIDs(0, NULL, &numPlatforms);
if (status != CL_SUCCESS)
    {
        std::cout << "Error: Getting platforms!" << std::endl;
        std::cin.get();
    }

我得到`错误：获得平台！`



当我执行'clinfo'时，我得到：在抛出'cl :: Error'实例后调用终止



我正在使用AMD驱动程序14.4和SDK 2.9（在AMD安装指南中提到，设置这两个文件将处理icd和环境变量的注册）



我做错了什么我不能让我的编程工作吗？



并不是说我正在使用Eclipse和lib的正确路径（/ opt / AMDAPP / lib / x86_64）。程序编译正确。

I get `Error: Getting platforms!`

When I execute 'clinfo', i get : terminate called after throwing an instance of 'cl::Error'

I am using AMD driver 14.4 and SDK 2.9 (it is mentioned in AMD installation guide, that setting up these two file will handle registration of icd and environmental variables)

What am i doing wrong that i cannot get my prog working?

not that I am using Eclipse with correct path to lib (/opt/AMDAPP/lib/x86_64). the program compiles correctly.

推荐答案

嗨。所以我找到了解决方案。似乎有一个订单根据你应该设置opencl支持。



即使您使用的是英特尔处理器，我们要做的第一件事就是安装AMDAPP SDK 2.9。

比重启PC

运行`clinfo`以确认正在检测CPU。

比GPU，安装AMD 14.4驱动程序包x64。

重新启动并运行`clinfo `确认正在检测GPU。



能够在没有链接的情况下获得标题：



sudo cp -r / opt / AMDAPP / include / * / usr / include /



一些依赖项



sudo apt-get install libglu1-mesa-dev



比在Eclipse中，添加正确的lib位置和-lOpenCL标志

hi. so i found the solution. it seems there is a order according to which u should set up opencl support.

even when u are using intel processor, first thing we have to do is install AMDAPP SDK 2.9.
than restart PC
run `clinfo` to confirm that CPU is being detected.
than for GPU, install the AMD 14.4 driver pack x64.
restart and run `clinfo` to confirm that GPU is being detected.

To be able to get header without linking:

sudo cp -r /opt/AMDAPP/include/* /usr/include/

some dependencies

sudo apt-get install libglu1-mesa-dev

than in Eclipse, add the correct lib location and -lOpenCL flag
