[Ipopt] [Cbc] Linear System Constraint Least Square

Sorry, I guess my answer wasn't too clear on a few points. The bottom line
is that you need a Fortran compiler to build Ipopt. If you want to build
Ipopt with Visual Studio, the only way I have successfully done it is using
the Intel Fortran compiler along with the Visual Studio compiler. There may
be some other ways to do it (you can build MSVC++ compatible libraries with
the MinGW compilers for instance, though I've never done it), but this is
by far the easiest. Actually, the only way to build the whole stack "out of
the box" with the Visual Studio compilers is to use the autotools and the
MSys shell, i.e., not the Visual Studio IDE. Keep in mind, though, that the
binaries for ipopt, Bonmin, Couenne, etc only work through AMPL.

To clarify one other point, the OS project is not just for building Web
service applications. It provides libraries and binaries that work in the
usual way, but wrap the other solvers and provide a uniform interface to
them, including an XML-based format for specifying instances. I've
cross-posted this to the more relevant lists in case others want to comment.

Cheers,

Ted
