[Ipopt] Cannot run Ipopt with AMPL Student Edition

[Stefan Vigerske]

Hi,

you need to provide AMPL with the ipopt executable that contains the 
AMPL/IPOPT interface.
After download of Ipopt and 3rd party codes (linear solver, ASL, Blas, 
Lapack) and build you should find the ipopt exectuable in the bin 
directory of the directory where you have build Ipopt.

Best,
Stefan
