opencl 프로그램 빌드가 실패했습니다

Question

다음은 2 차원 배열을 2 개 추가하기 위해 작성한 코드입니다. 점점 복잡해 지지만 실행하려고 할 때 오류가 발생합니다 : 프로그램을 작성하지 못했습니다. runtime0.0000 왜 prpgram이 만들어지지 않았습니까? 또한 내가 쿼리 한 빌드 로그가 표시되지 않는 이유는 무엇입니까? 사실 배열을 초기화하는 중이므로 2 차원에서 1 차원으로의 변환은 표시되지 않고 1 차원 배열에 직접 저장되었습니다.

커널 :

kernel void array_add_kernel(
const int n, const int m, const p, _global const float * A, _global const float * B, , _global float * C) 
{ 
int i= get_global_id(0); 
int j= get_global_id(1); 
C[i*m + j] = A[i*m + j] + B[i*m + j]; 
}

커널을 수정합니다. 그것은 오류로 가득 차 있습니다.

kernel void array_add_kernel(
const int n, 
const int m, 
const p, // No type specifier 
_global const float * A, // Should be global, not _global 
_global const float * B, , // Double comma 
_global float * C) 
    { 
    int i= get_global_id(0); 
    int j= get_global_id(1); 
    C[i*m + j] = A[i*m + j] + B[i*m + j]; 
    } 

이것은 작동 커널입니다.

kernel void array_add_kernel(const int n, const int m, global const float * A, global const float * B, global float * C) 
{ 
int i= get_global_id(0); 
int j= get_global_id(1); 
C[i*m + j] = A[i*m + j] + B[i*m + j]; 
}
