Question

我刚开始学习OpenCL。当我输入make来编译HelloCL程序时，我收到以下错误：

mkdir -p depends/x86_64
perl ../../../../../make/fastdep.pl -I. -I../../../../../include  -I../../../../../samples/opencl/SDKUtil/include --obj-suffix='.o' --obj-prefix='build/debug/x86_64//' HelloCL.cpp > depends/x86_64/HelloCL.depend
mkdir -p build/debug/x86_64/

有人可以帮助我理解我看到的错误，并建议需要进行更正吗？

Answer 1

您的SDK支持的OpenCL版本似乎不采用您使用的cl.hpp。试试cl.hpp from the Khronos site。

Answer 2

我建议从以下网址下载最新的AMD APP SDK：http://developer.amd.com/sdks/AMDAPPSDK/downloads/Pages/default.aspx

尝试再次运行示例，此SDK支持：OpenCL 1.2，因此您不应该看到任何问题。
