Hi again:

My problem continue, I have followed the post (
http://list.coin-or.org/pipermail/ipopt/2011-September/002598.html) but is
very general and I dont know what I need to do.  He talk to recompile, but
I don't have the project solution of that dll and I dont Know how link
Fortran with C++.

On the other hand, the .zip files Ipopt-3.9.2-win32-win64-dll.7z and
Ipopt-3.9.1-win32-win64-dll.7z  in
http://www.coin-or.org/download/binary/Ipopt/ are corrupted.

Please, could anyone give me more details or other suggestions?
Best Regards
Juan Carlos


The IpoptApplicationFactory is usually only needed for the C and Fortran
interface wrappers, I think. Does some example that uses the C++
interface directly work?

It may be an issue with VS9 vs VS10. I heard that there are some
The binaries you downloaded were created by VS9.

Under the above link, they also discuss a way to build Ipopt with the
C/C++ compiler from VS10, but linking against precompiled Fortran libraries.



Hi all:

I am new using Ipopt and I have a problem when I try to use this library. I
have downloaded the binary zip file (Ipopt-3.10.1-win32-cl15icl11.1.zip)
and I have created a Visual Studio 10 solution and I have referenced the
lib file and include file. When I try to excute a example I have the
following error:

1> main.obj: error LNK2019: unresolved external symbol
_IpoptApplicationFactory that is referenced in function _main

Could anyone give me some help of suggestions about this error?
Best regards
Juan Carlos
