[Ipopt] Compilation of IPOPT library for C++ example in MSVC(Ipopt.sln)

[Teeter, Chuck]

Hi Antonio,
 
 
I noticed the same problem as well, and to fix it, I had to manually add
source files (.cpp) to the IPOPT project as needed until the link errors
stopped.  These files were included in the IPOPT source distribution,
but were not part of the VS solution (.sln) file.  Although I'm not sure
how this file was created in the first place, it is easy in Visual
Studio to create a separate project (for example, a win32 console app)
to represent your model.  Then, you just have to set (the already built)
IPOPT.lib as a project dependency which is then linked to your code.
However, your project will still need to reference the IPOPT include
files in a manner similar to what's done in the VS solution file that's
included with IPOPT.   To resolve any unresolved external link errors,
you will then need to make sure that the needed source file(s) is part
of your IPOPT library build.  I don't recall having to change any of the
include directories to build IPOPT; I just remember having to manually
add a few source files.
 
Depending on the location of your new Visual Studio project, you may
still need to adjust the relative paths for the include directories so
the IPOPT header files can be located at compile time.

Hello,

When I try to exactly reproduce from scratch the example that comes with
the IPOPT 3.8.0 installation (the one under the v8 subdiretory that has
a pre-processed/pre-compiled solution called Ipopt.sln) in MSVC 8.0, I
get lot's of unresolved references errors related to the #Include
directive, e.g., the compiler seems not to link IpIpoptApplication.hpp
and hs_071_nlp.hpp to the solution. I know this might be a very silly
question, but how was the solution Ipopt.sln created for MSVC? Was it
created using the MSVC itself or Cywin or other program? In other words,
how can I create a new IPOPT problem using MSVC such that I do not have
to tell MSVC all the Include File dependencies?

Thanks a lot!

Cheers,
Antonio.
