I downloaded the VF13OptimizerPlugin code and followed the instructions as lined out in the associated README file:
https://sourceforge.net/p/gmatplugins/g ... les.txt#l3
But when trying to build the VS2010 project (with VS2010 as required) I ran into the following problems :
1. I had to add include paths to "GMAT\src\base\solarsys" and "GMAT\src\base\coordsystem". Not a major issue.
2. I get the following compile errors (major issue):
Error 1 error C2259: 'VF13ad' : cannot instantiate abstract class C:\Users\mba\gmatplugins-gitcode\VF13OptimizerPlugin\src\base\factory\VF13Factory.cpp 48 1 libVF13Optimizer
Error 4 error C2259: 'VF13ad' : cannot instantiate abstract class C:\Users\mba\gmatplugins-gitcode\VF13OptimizerPlugin\src\base\solver\VF13ad.cpp 174 1 libVF13Optimizer
Error 5 error C2664: 'vf13ad_' : cannot convert parameter 1 from 'Integer *' to 'integer *' C:\Users\mba\gmatplugins-gitcode\VF13OptimizerPlugin\src\base\solver\VF13ad.cpp 1152 1 libVF13Optimizer
Error 6 error C2065: 'initialized' : undeclared identifier C:\Users\mba\gmatplugins-gitcode\VF13OptimizerPlugin\src\base\solver\VF13ad.cpp 1244 1 libVF13Optimizer
Error 8 error C2065: 'initialized' : undeclared identifier C:\Users\mba\gmatplugins-gitcode\VF13OptimizerPlugin\src\base\solver\VF13ad.cpp 1396 1 libVF13Optimizer
I suspect that the available VF13OptimizerPlugin code is not up to date with GMAT 2016a, or it may be that I am doing something wrong which is not unheard of

Very grateful for any advice!
