[Ipopt] Problems building parallel IPOPT version from v8-ifort

[Stefan Brugger]

Hi,

I want to build IPOPT with MKL and parallel Mumps from the v8-ifort VS project files. I could successfully build a sequential version but what is the easiest way to build a parallel one?

Until now I tried the following:
I installed MPICH2 and replaced all includes to the Mumps libseq folder with the include folder of MPICH2. Furthermore I uncomment the following define

       // The following line is a fix for otherwise twice-defined global variable
       // (This would have to be taken out for a parallel MUMPS version!)
       # define MPI_COMM_WORLD IPOPT_MPI_COMM_WORLD

in the IpMumpsSolverInterface.cpp, as explained by the comment.

Now I'm getting the following errors if building the IpOpt project:

IpMumpsSolverInterface.cpp
6>c:\program files\mpich2\include\mpicxx.h(234): error C2526: 'MPI::Datatype::Create_struct' : C linkage function cannot return C++ class 'MPI::Datatype'
6>          c:\program files\mpich2\include\mpicxx.h(171) : see declaration of 'MPI::Datatype'

Has anyone builded a parallel version from the v8-ifort project files? If yes how did you do it? Or can anybody help me with the error messages?

Best regards,
Stefan
