Below I show how I adapted/complied the example MyModule included on github and the error message I get (bottom of email).

The steps look generally good.

two absolute paths inserted (correct missing file error):
#include "/home/nest/work/nest-simulator-2.18.0/sli/slifunction.h"
#include "/home/nest/work/nest-simulator-2.18.0/sli/slimodule.h"

You should not need the absolute paths, just the filenames should suffice.

$ cd mmb
$ cmake -Dwith-nest=${NEST_INSTALL_DIR}/bin/nest-config ../My2Module
$ make

Could you post the output of the cmake command?

And also the output of the following command

${NEST_INSTALL_DIR}/bin/nest-config --prefix --includes --libs --cflags

Best,

Hans Ekkehard

Hi Allen,

Several steps are required to add a model to NEST. The recommended way of adding a model is to create your own NEST module outside the NEST source code tree. You will find an example in examples/MyModule and more documentation at https://nest.github.io/nest-simulator/extension_modules.

Placing code for custom models in the models directory in the NEST source code tree also works, but makes it more difficult to move to newer versions of NEST or to share your custom models with colleagues.

Briefly, in addition to adding the source code files to the models directory, you need to

1. add the files to models/CMakeLists.txt
2. #include the files in models/modelsmodule.cpp
3. add a line like

register_connection_model< StaticConnection >( "static_synapse" );

for each model. The template parameter is the model class, the string the name it will have in NEST
4. recompile and reinstall NEST

Best,
Hans Ekkehard

Dear Nest Community,

Would anyone have insight into why I'm getting an UnknownModelName error?

I'm new to Nest and am using Nest 18.0 on Lubuntu Virtual Box (Windows 10 OS).

Thanks for any help.

Best Regards,
