parsing integer array on JSONcpp

I'm having trouble parsing integer arrays using JsonCpp. I am trying to read an array of integers from json input. I'm getting the error:

ambiguous overload for 'operator[]' in 'dataArray[0]'

I've tried:

Json::Value c_val;
const Json::Value dataArray = root["data"];
c_val = dataArray[0];   int a = c_val.asInt();
c_val = dataArray[1];   int b = c_val.asInt();

and I've also tried

int a = dataArray[0];

To no avail. Sample input json file:

{
 "data" : [ 1047, 140, 60, 60 ]
}
Solution

  • For future reference:

    Force integer input with '0u':

    c_val = dataArray[0u];   int a = c_val.asInt();

    solves it.
