[Ipopt] IpOpt compiling problem in MSVC 10

[Stefan Vigerske]

Hi,

there is a fix for it, but it hasn't made it into a release yet:
https://projects.coin-or.org/Ipopt/changeset/2492/trunk
You essentially need to add src/Common/IpTaggedObject.cpp back into the 
list of files that need to be compiled.
