Maximize[{g + (1 - g)*x - (g/2)*x^2 - (g/2)*v,
   x == (a/c) + Sqrt[(d/c)*(v - 1/c)]}, {x, g, v, c, d}]

{\[Infinity], {x -> Indeterminate, g -> Indeterminate,
   v -> Indeterminate, c -> Indeterminate, d -> Indeterminate}}

I suspect that's the right answer, since none of the variables are  
specified.
