SIGV на ClgetPlatformids ⇐ C++

[Anonymous]

Существует Sigv Wile Clgetplatformids, который иногда является фатальным sigsegv. < /p>
Минимальный экземпляр, который я обнаружил, создавая его: < /p>
#include
#include
#include "CL/cl.h"

int main()
{
printf("Programme successfully opened!\n");
cl_uint num;
int ret = clGetPlatformIDs(0, nullptr, &num);
printf("Num platforms: %d \n", num);

return 0;
}

Я попытался найти решение этой проблемы, даже давая в качестве второго параметра, а не nullptr, а также допустимая память, но это ничего не делает. Я использую Linux с помощью видеокарты Intel.
Я не знаю, поступает ли эта проблема из моего кода, OpenCl, пакета или даже конкретной реализации поставщика. < /P>
