Hi Allen,

Thanks. It looks like a relative path has ended up in your nest-config file where it should have been an absolute path. Could you open file

 nest-install/bin/nest-config 

and go to roughly line 55, where you should find something like

    --includes)

        echo " -I/home/nest/work/nest-simulator-2.18.0/conngen  -I../nest-install/include/nest -I/usr/include -I/usr/include -I/usr/local/include -I/usr/include -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi/opal/mca/event/libevent2022/libevent -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi/opal/mca/event/libevent2022/libevent/include -I/usr/lib/x86_64-linux-gnu/openmpi/include"

        ;;

Please replace within

-I../nest-install/include/nest

the .. with the absolute path. Then run cmake and make again in the My2Module build directory. You may want to delete anything in that build directory first to avoid old Cmake cached data.

Best,

Hans Ekkehard

You can now build and install 'my2module' using
  make
  make install

The library file libmy2module.so will be installed to
  /home/nest/work/nest-install/lib/nest
Help files will be installed to
  /home/nest/work/nest-install/share/doc/nest

The module can be loaded into NEST using
  (my2module) Install        (in SLI)
  nest.Install('my2module')  (in PyNEST)

The module will be installed into a non-default location!
Make sure to set the environment variables:
  export NEST_MODULE_PATH=/home/nest/work/nest-install/lib/nest:$NEST_MODULE_PATH
  export SLI_PATH=/home/nest/work/nest-install/share/nest/sli:$SLI_PATH

Hi Allen,

  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,
