[ndnSIM] Call engine.h in ndnSIM

[Alex Afanasyev]

Hi Amin,

The problem is that you need to specify that your program needs to be compiled with MATLAB dependency (with proper CXXFLAGS and LINKFLAGS).  I'm not quite confident how to do it with scratch/ folder, but if you have created a separate scenario repository or configured your scenario in src/ndnSIM/examples/wscript (and put it under src/ndnSIM/examples), then you may do the following:

1. Edit src/ndnSIM/wscript 

somewhere (in the beginning) of `def configure(conf):`

conf.env['INCLUDES_MATLAB'] = '<path-to-matlab-folder-where-engine.h-exists>'
conf.env['LIB_MATLAB'] = ['<matlab-library>']
conf.env['LIBPATH_MATLAB'] = '<path-to-matlab-library>'


I'm not sure, but according some Internet posts, the second line should be something like:

conf.env['LIB_MATLAB'] = ['eng', 'mat', 'mx']

and third should be location of libeng.dylib/libeng.so, libmat.dylb/libmat.so, libmx.dylib/libmx.so libraries within MATLAB


2. Edit src/ndnSIM/examples/wscript

Edit/create definition for your program to look like this

    obj = bld.create_ns3_program('your-app', all_modules)
    obj.source = 'your-app.cc'
    obj.use += ['MATLAB']
