build error using Custom data types with Thrust Vectors and Cuda

Question

I am using Thrust vectors for cuda kernels and i have created my own struct so i can pass in all of the data together, when i initialise a host vector of my custom type i get a build error from thrust.

initialisation of the vector:

host_vector<PhysicsData> physicsDataVector(numPeople + 1, 0);

custom data type:

__device__ __host__ struct PhysicsData {
    vector3 position;
    vector3 velocity;
    vector3 acceleration;
    vector3 force;
    float massInvert = 1.f;
    float drag = 1.f;
    bool dead = false;

    __device__ __host__ PhysicsData(){
        massInvert = 1.f;
        drag = 1.f;
        dead = false;
        position = vector3();
        velocity = vector3();
        acceleration = vector3();
        force = vector3();
    };
};

Error:

Answer 1

The issue was I was using the wrong constructor for the vector, I for some reason had a , 0 in my constructor so changing it to this fixed it

physicsDataVector(numPeople + 1);
