[Ipopt] [mumps-users] Ipopt MUMPS interface and MPI problems

[Stefan Vigerske]

Hi,

There is a check for MPI_Initialized in configure, which should make 
sure that HAVE_MPI_INITIALIZED is defined in case the function is available.
Did you have to set it by hand because you use a selfmade build system, 
or does the check in configure not work in your case? If the latter, it 
might be interesting if it could be fixed.

Stefan
