std::make_pair with float array (float2, unsigned int)

std::make_pair with float array (float2, unsigned int)

I have a vector containing templated with a float2, unsigned int pair like:
std::vector<std::pair<float2, unsigned int>> myVec;
And then I'm trying to add such a pair to the vector:
unsigned int j = 0;
float2 ab = {1.0, 2.0};
myVec.push_back(std::make_pair(ab, j));
This is how I expect it should work, though when I try to compile it I get
the error:
1>C:\Program Files (x86)\Microsoft Visual Studio
10.0\VC\include\utility(163): error C2536:

What is the correct way to add this data type to my pair holding vector?
The float2 type is defined as:
typedef float float2[2];
