Hi
My two cents:
1. high-level solution: use my piece of software wasora from
www.seamplex.com/wasora that inputs a human-friendly input file and
interfaces with GSL. For example, this file
https://bitbucket.org/seamplex/wasora/src/master/examples/solve.was
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
https://bitbucket.org/seamplex/wasora/src/master/src/multiroot.c
