Good evening to all,
I'm currently working on a project developed with GeNN, a neural network simulator that works with CUDA, on Windows. In this project, I have the need to use a library for some matrix computations with several data, then I discovered Eigen library and I decided to use it due to its simplicity. I tested some capabilities with Dev-C++ and all worked fine.
The problem is what happens when I want to include Eigen within my GeNN project. Just to give you an idea: GeNN requires two main files, one dedicated to the neural network model definition and the other that deals with the simulation.
Here, there's the code of the model: http://pastebin.com/MkPVdvBJ
and here there's the simulation code: http://pastebin.com/CaXxpUEG
In particular, Eigen is used within the second file I reported but I cannot understand why it gives me a lot of errors when I try to compile it. This is what I type on command prompt for compiling it:

Code: Select all

nmake /f WINmakefile clean && nmake /f WINmakefile

and this is the result:

I cannot understand what goes wrong, but I hope you'll help to solve this bunch of errors.

I'm not sure why it fails because nvcc compiles fine Eigen, but it might help to only include <Eigen/LU> instead of <Eigen/Dense> and to split your file into a .cpp file for pure CPU code, and a .cu file for cuda related stuff only.
