[Ipopt] Need Help Linking MUMPS with Ipopt Application

[Stefan Vigerske]

Hi,

this symbol should be defined in the libseq of Mumps.
In the file mpic.c, these functions are defined.

Maybe there is a name mangling problem. You should check if both
functions have the same name in the libseq and ipopt library.
(under unix the tool is nm, for visual studio I don't know)
