那些遇到过的问题

方便的方式来显示OpenCL错误代码？

Sel*_*mar 13 error-code opencl

根据标题,是否有一种方便的方式来显示可读的OpenCL错误代码？

能够将"-1000"之类的代码转换为名称可以节省大量浏览错误代码的时间.

这就是我目前所做的.我相信OpenCL 1.2的错误列表是完整的.

cl_int result = clSomeFunction();

if(result != CL_SUCCESS)
    std::cerr << getErrorString(result) << std::endl;

并且getErrorString定义如下:

const char *getErrorString(cl_int error)
{
switch(error){
    // run-time and JIT compiler errors
    case 0: return "CL_SUCCESS";
    case -1: return "CL_DEVICE_NOT_FOUND";

对于任何需要不同版本的OpenCL错误代码的人来说,这里有一个小脚本可以帮到你.

$ ./clext.py /directory/to/opencl/headers
Run Code Online (Sandbox Code Playgroud)

例如,要为OpenCL 2.2创建错误代码到字符串帮助功能,您可以运行

$ ./clext.py ~/Developments/OpenCL-Headers/opencl22/CL
Run Code Online (Sandbox Code Playgroud)

将clext.h在当前目录中创建一个文件.

然后,您可以在项目中包含此文件,并使用该调用const char* clGetErrorString(int errorCode)从错误代码中获取错误字符串.

以下是clext.hOpenCL 2.2 生成的文件的内容.
