[NEST Users] Re: Writing an extension module with MyModule

Hi Raymond,

You will find the MyModule code in the examples subdirectory in the nest-2.20.1 sources. For NEST 3, we have moved extension module code out of the NEST repository to its own: https://github.com/nest/nest-extension-module

Instead of writing your own module to implement a kernel function for the NEST topology module, you might want to consider to switch to NEST 3 right away (using the sources from the NEST master branch). NEST 3 allows you to specify essentially arbitrary kernel functions at the C++ level. See

Hello,

I would like to add a kernel function to use with NEST topology, and am attempting to

follow the instructions at http://nest.github.io/nest-simulator/extension_modules and https://nest-simulator.readthedocs.io/en/nest-2.20.1/topology/Topology_Us..., which both mention the MyModule example in the examples folder of the NEST distributable. However, I can't find such an example in my local NEST files, or in the github repository (https://github.com/nest/nest-simulator).

Is there another location I should be looking in for this example, or would someone be

kind enough to send me the necessary files?

Many thanks,
Raymond Hawkins

Hi Hans Ekkehard,

It has been a few days since I posted my last reply so I would like to follow up for a response. Would you please be able to provide a bit more detail as to installing NEST 3.0 from the source code. Is the source code at https://github.com/nest/nest-simulator the most up to date version or is it still NEST 2.0? I also noticed the installation instruction file is no longer in the source code. Is there somewhere I can find up to date installation instructions? I attempted to follow the instructions available here (https://nest-simulator.readthedocs.io/en/stable/installation/linux_install.h...) but cannot find the tar ball in the source code. We are very excited to use the new topology features in the 3.0 version so any help you can provide would be very appreciated!

Many thanks, Raymond Hawkins
