Dear Justin,

I still have problems with performing l-bfgs minimization.
I use

constraints              = none ; no constraints
define                   = -DFLEXIBLE

in my *mdp file and in *top file there is nothing related to constraints.
I still get this error that l-bfgs and constraints are not implemented.
What am I missing?
