显示OpenCL错误代码的便捷方法？
根据标题，是否有一种方便的方式来显示可读的OpenCL错误代码显示OpenCL错误代码的便捷方法？,opencl,error-code,Opencl,Error Code,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'这样的代码转换为名称将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OpenCL1.2的错误列表是完整的 cl_int result = clSomeFunction(); if(result != CL_SUCCESS) std::cerr << getErrorString(result) << std::endl; 对于任何需要不同版本OpenCL错误代码来字符串
能够将'-1000'这样的代码转换为名称将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OpenCL1.2的错误列表是完整的
cl_int result = clSomeFunction();
if(result != CL_SUCCESS)
std::cerr << getErrorString(result) << std::endl;
对于任何需要不同版本OpenCL错误代码来字符串的人来说，一个小脚本可以帮助你
