My two cents:

1. high-level solution: use my piece of software wasora from that inputs a human-friendly input file and
interfaces with GSL. For example, this file
solves the system of equations

  y = exp(-f(z)*x)
  x = integral(f(z'), z', 0, z)
  2 = x+y+z

where f(z) is a pointwise-defined function like

$ wasora solve.was 
 x =    0.319603
 y =    0.784170
 z =    0.896227

2. low-level solution: see
