it's difficult to say why it fails without more details.
The config.log file in the Ipopt subdirectory should show some details
about the test that checks whether the wsmp library is working.

> Ipopt/wsmp appears to be a very good solution for large-scale problems: I have been able to solve problems as large as ca. 400000 vars and equlity constraints Jacobian with ca 3000000 nonzero elements. However, for the solver to work well I need to set the following options:
> linear_system_scaling=mc19
> linear_scaling_on_demand=yes
> linear_solver=wsmp
> wsmp_scaling=2 (turn off internal wsmp scaling)
> If I let wsmp do its own scaling of the linear system we do not get converged solutions.
> Our first trials with Ipot/pardiso have been unsuccessful: the solver does not converge! There must be some problem with the interface with this solver.
