Hi Rodrigo,

We have not implemented Arvind's modifications of Ipopt fpr MPECS in the 
C++ version - it is only part of the Fortran version.

You can still download the Fortran version as tarball at


In order to activate the MPEC modications (only available from AMPL), you 
need to run the configure script with --enable-mpcc

I hope this helps,
