I'm trying to simulate a video streaming network using OPNET 14.5A.

I setup OPNET to use Visual Studio 2012 as a compiler and I'm using OpenCV 2.4.10.

When running an OPNET simulation I get the following error:

Creating library C:\opnet_projects\4nodes.project\4nodes-scenario1.dev32.i0.nt.lib and object C:\opnet_projects\4nodes.project\4nodes-scenario1.dev32.i0.nt.exp

I've setup Microsoft.Cpp.Win32.user.props file the following way:

- C/C++ -> General -> Additional Include Directories  
C:\OpenCV2.4\opencv\build\include  
C:\OpenCV2.4\opencv\build\include\openc­v  
C:\OpenCV2.4\opencv\build\include\openc­v2  

- Linker -> General -> Additional Library Directories  
C:\OpenCV2.4\opencv\build\x86\vc11\lib

- Linker -> Input -> Additional Dependencies  
opencv_calib3d2410d.lib  
opencv_contrib2410d.lib  
opencv_core2410d.lib  
opencv_features2d2410d.lib  
opencv_flann2410d.lib  
opencv_gpu2410d.lib

opencv_photo2410d.lib  
opencv_stitching2410d.lib  
opencv_superres2410d.lib  
opencv_ts2410d.lib  
opencv_video2410d.lib  
opencv_videostab2410d.lib  

- Added the following to my Path System Variable  
C:\OpenCV2.4\opencv\build\x86\vc11\bin;

Please help me understand what I am doing wrong in setting up my testing environment.

I received and answer to this question from another source, here's the answer for reference.

Since Modeler calls the compiler and linker directly, I do not think the Microsoft.Cpp.Win32.user.props file will be used. Instead, you can add the settings as compiler and linker options in the Modeler preferences.

The include directories can be added to "Common Flags for All Code", the library directories can be added to "Common Network Repositories Flags", and the library names can be added to "Common Network Repository Libraries". (The full names of the preferences may be different in 14.5, but I do not think the tags have changed. They are 'comp_flags_common', 'bind_shobj_flags' and 'bind_shobj_libs', respectively.)

Add '/I' before each include directory, and add '/LIBPATH:' before the library directory. - See more at: https://splash.riverbed.com/message/22918#22918
