[Ipopt] HSL libraries question

[Ashutosh Mahajan]

hello everyone,

im very new to IPOPT and to nonlinear programming as well. i just built
version 3.6.0 with MA57, MA27, Metis and AMPL-ASL. the solver seems to work.
i can solve small instances like 3pk.mod but im not sure if the solver is
using MA57 and Metis. I see the message:

This is Ipopt version 3.6.0, running with linear solver ma27. 

but nothing about ma57 and/or metis. how can i be sure that ipopt is using
these? i see ma57ad.lo in the build directory. is that the only sign that its
included?

thanks.
