using nlopt c++ in windows MSVC with BFGS algorithm

[jbensabat]

Hello I am trying to set a optimization problem (objective function, upper bound and lower bound constraints) using the gradient based optimization (BFGS). When I used c++ version (nlopt.hpp) i get a failure but when I run the same algorithm with the c version (nlopt.h) it runs fine. Is this a bug ? or I am doing something wrong? best jac
