Hi :
I compile using MSVC and Intel Fortran using the configure script under Cygwin.. I created both release and debug versions of the library.
I now uses the compiled libraries in visual studio. After some experimentation, the following worked for me. For the debug version, I disable MSVCRTD.LIB, MSVCPRTD.LIB and LIBCMT.LIB. For the release version I disable MSVCRT.LIB and MSVCPRT.LIB.
Hope this helps.

Hey guys:
Based on Damien's suggestion I tried different permutations of nodefaultlib
to no avail. I am taking one last crack at linking to this in a debug build
before getting into the building world (release is working sufficiently for
now I believe)
* I changed the /Code Generation/Runtime Library to Multi-threaded Debug
(/MTd) from the default dll version
* I link to just libipopt.lib (adding in others didn't seem to help).
* without setting any /nodefaultlib I get a bunch of duplicates like the
following, all mentioned are from libcmt.lib such as:
1>LIBCMT.lib(invarg.obj) : error LNK2005: __initp_misc_invarg already
defined in LIBCMTD.lib(invarg.obj)
1>LIBCMT.lib(invarg.obj) : error LNK2005: __invoke_watson already defined in
LIBCMTD.lib(invarg.obj)
* With setting /NODEFAULTLIB:libcmt I get a bunch of unresolved symbols:
1>cpp_example.cpp
1>Linking... (Intel C++ Environment)
1>xilink: executing 'link'
1>libipopt.lib(IpSumMatrix.obj) : error LNK2001: unresolved external symbol
__invalid_parameter_noinfo
....
* With setting /NODEFAULTLIB:libcmtd I get 4 unresolved symbols:
1>LINK : warning LNK4098: defaultlib 'LIBCMT' conflicts with use of other
libs; use /NODEFAULTLIB:library
1>libcpmtd.lib(stdthrow.obj) : error LNK2019: unresolved external symbol

(?_Debug_message at std@@YAXPB_W0I at Z)

int,struct std::_DebugHeapTag_t const &,char *,int)"

superset of those) I get an enormous number of unresolved symbols
If anyone has any last minute suggestions on a permuation, I would love to
give it a shot. Otherwise, do you suggest I try to make the windows
binaries with Visual Studio or MingGW instructions? Which do you think is
easier to get working for building the 4 permutations of builds
(debug/release and multithreaded/multithreaded-dll)? Also, do you expect
that I will have trouble with the multi-threaded dll build? I am using /MDd
for my other libraries and am worried I may run into the opposite problem
changing those over.

I lost track already. How was that one build, multithreaded or
multithreaded-debug?

If possible, then you should have all libraries build with the same
flag, that is all debug, or all multithreaded-dll, or whatever...
If you build Ipopt with Visual Studio and wanna use MUMPS, then I don't
know how VS will know how to compile this Fortran90 package.
When you follow the MinGW instruction, you can overwrite compiler flags
(CFLAGS, CXXFLAGS, FFLAGS) to make sure that they all use the same
-MT/-MTd/... flags. It should be correct already for the default build
(=-MT), but for the debug build I'm not sure.
