如何使用GCC与Windows 7上的英伟达工具包编译和链接OpenCL？ 英伟达GPU计算工具包安装在E:\程序文件\Nvidia GPU计算工具包\CUDA\V4.2\，我尝试编译OpenCL示例程序： gcc hello.c -I "E:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.2\include" -L "E:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.2\lib\Win32" -lOpenCL -o hello.exe

我有链接器错误：

怎么了？如何让它工作？

在阅读了一些相关的问题后，我安装了mingw utils，然后在上使用

dlltool-l libOpenCL.a-d OpenCL.def-a-k

并使用：

gcc hello.c-I“E:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v4.2\include“--lOpenCL-o hello.exe

编译它。现在它可以正常编译和工作
