DPCT1055

Message

Vector types with size 1 are migrated to the corresponding fundamental types, which cannot be inherited. You need to rewrite the code.

Detailed Help

The warning message is emitted when vector type with size 1 is inherited by a class or struct in the original code. Since the vector type with size 1 is migrated to the corresponding fundamental type in DPC++ and the fundamental type cannot be inherited, you need to rewrite the code.

Suggestions to Fix

You can declare a new field with the corresponding fundamental type, for example int for int1, in the class/struct and override the required operators.

For example, the following migrated DPC++ code:

1
2
3
class MyClass : int {
  ...
}

is manually adjusted to:

1
2
3
4
5
class MyClass {
  int x;
  MyClass operator+(const MyClass& y) { ... }
  MyClass operator=(const MyClass& y){...}...
}
