c++ - Two point boundary with odeint -

i trying solve 2 point boundary problem odeint. equation has form of

y'' + a*y' + b*y + c = 0 

it pretty trivial when have boundary conditions of y(x_1) = y_1 , y'(x_2) = y_2, when boundary conditions y(x_1) = y_1 , y(x_2) = y_2 lost. know way deal problems odeint or other scientific library?

in case need shooting method. odeint not have such method, solved initial value problem (ivp) first case. think in numerical recipies method explained , can use boost.odeint time stepping.
