ओपनसीएल त्रुटि कोड दिखाने के लिए सुविधाजनक तरीका?

Question

शीर्षक के अनुसार, क्या पठनीय ओपनसीएल त्रुटि कोड दिखाने का कोई सुविधाजनक तरीका है?

'-1000' जैसे कोडों को कन्वर्ट करने में सक्षम होने से त्रुटि कोड के माध्यम से ब्राउज़ करने में काफी समय बचा होगा।

Answer 1

यही वह है जो मैं वर्तमान में करता हूं। मुझे विश्वास है कि ओपनसीएल 1.2 के लिए त्रुटि सूची पूरी हो जाएगी।

cl_int result = clSomeFunction(); 

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

और getErrorString के रूप में परिभाषित इस प्रकार है:

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"; 
    case -2: return "CL_DEVICE_NOT_AVAILABLE"; 
    case -3: return "CL_COMPILER_NOT_AVAILABLE"; 
    case -4: return "CL_MEM_OBJECT_ALLOCATION_FAILURE";

    case -47: return "CL_INVALID_KERNEL_DEFINITION"; 
    case -48: return "CL_INVALID_KERNEL"; 
    case -49: return "CL_INVALID_ARG_INDEX"; 
    case -50: return "CL_INVALID_ARG_VALUE"; 
    case -51: return "CL_INVALID_ARG_SIZE"; 
    case -52: return "CL_INVALID_KERNEL_ARGS"; 
    case -53: return "CL_INVALID_WORK_DIMENSION"; 
    case -54: return "CL_INVALID_WORK_GROUP_SIZE"; 
    case -55: return "CL_INVALID_WORK_ITEM_SIZE"; 
    case -56: return "CL_INVALID_GLOBAL_OFFSET"; 
    case -57: return "CL_INVALID_EVENT_WAIT_LIST";

    case -67: return "CL_INVALID_LINKER_OPTIONS"; 
    case -68: return "CL_INVALID_DEVICE_PARTITION_COUNT"; 

    // extension errors 
    case -1000: return "CL_INVALID_GL_SHAREGROUP_REFERENCE_KHR"; 
    case -1001: return "CL_PLATFORM_NOT_FOUND_KHR"; 
    case -1002: return "CL_INVALID_D3D10_DEVICE_KHR"; 
    case -1003: return "CL_INVALID_D3D10_RESOURCE_KHR"; 
    case -1004: return "CL_D3D10_RESOURCE_ALREADY_ACQUIRED_KHR"; 
    case -1005: return "CL_D3D10_RESOURCE_NOT_ACQUIRED_KHR"; 
    default: return "Unknown OpenCL error"; 
    } 
} 

Answer 2

जो कोई स्ट्रिंग के लिए OpenCL त्रुटि कोड के विभिन्न संस्करण की आवश्यकता के लिए, here एक छोटे से स्क्रिप्ट आपकी मदद कर सकता है।

$ ./clext.py /directory/to/opencl/headers 

उदाहरण के लिए, OpenCL 2.2 के लिए स्ट्रिंग मदद समारोह के लिए त्रुटि कोड बनाने के लिए, आप चलाने

$ ./clext.py ~/Developments/OpenCL-Headers/opencl22/CL 

अपने वर्तमान निर्देशिका में एक फ़ाइल clext.h पैदा करेगा कर सकते हैं।

फिर आप इस फ़ाइल को अपनी प्रोजेक्ट में शामिल कर सकते हैं और त्रुटि कोड से त्रुटि स्ट्रिंग प्राप्त करने के लिए const char* clGetErrorString(int errorCode) पर कॉल का उपयोग कर सकते हैं।

ओपनसीएल 2.2 के लिए जेनरेट की गई फ़ाइल clext.h की सामग्री यहां दी गई है। http://stackoverflow.com/questions/19134943/where-do-i-find-strings-for-error-code-in-opencl-nvidia:
