Hans,
Thank you for your suggestions on May 6th. I've since built my own
module, 'My2Module' per your guidance and that on
https://nest.github.io/nest-simulator/extension_modules
<https://secure-web.cisco.com/1OkG_4Lw1yXYSv9Bo1mMO2W05lnXnEL03XeGcAPY__8APmBFD6LJj5zzZE42doCxkKRobTud5P4AT-oAs4WO_e4LtGvMBLDNRl2akKXbAPU8F8r9Rm4A-tpRybnnEUh062b56HNleUWk7QJ6N1WbDPtfI2tSIZfBrNSy7ZS4MsvzYfYHFlpG8GQQde5gApJecM5CFQEEP9CGymqYZ18LQ3zj1pcYeYG_L4XhXZhfL9be5WtSMrDZVy_ZeB0g3Qorb-lhDrLguvPgqUhCze8vfsqesaXfTpE3HtpsEMUcfd3Xc5vUP1KU6rRWzSAw8az7wM5CxmAlax7wYyP8eT_0bQAweIakbsUW3bXaCT9znQv15l-qoBLExOyTKQvbcyNiwLEBNflla-_MsLueEemTJ1NRiHSI7kGavYtpaKaeXtlSy7q0YU9lIMHnnS0AWr5keolzddt0U0uCpJmO2uL9FUA/https%3A%2F%2Fnest.github.io%2Fnest-simulator%2Fextension_modules>.
Unfortunately it appears the NEST source directories ./libnestutil,
./nestkernal,, and ./sli are not visible/linked to my2module.cpp
Is this non-linkage to be expected as it forces every "#include' in
my2module.cpp and my STDP model to have its absolute path included?
Below I show how I adapted/complied the example MyModule included on
github and the error message I get (bottom of email).
Thank you for any further suggestions.
Best Regards,
--Allen
---------CREATE MODULE: 1 directory copied, 4 files updated, 2 files
added------------
1. Make Module directory
/home/nest/work/nest-install/examples/MyModule copied/renamed to:
/home/nest/examples/My2Module
Two files with new STDP model added:
stdp_izh_bitwise_correct_connection.cpp
stdp_izh_bitwise_correct_connection.h
2. Updated "myModule.cpp"
name changed to "my2Module.cpp", references within updated
New STDP Model Listed by adding line:
#include "stdp_izh_bitwise_correct_connection.h"
New STDP Model Registered with model manager by adding line:
nest.kernel().model_manager.register_connection_model<STDPIzhBitwiseCorrectConnection<nest::TargetIdentifierPtrRport
>( "stdp_izh_bitwise_correct_connection"
);]
3. Updated "myModule.h"
name changed to "my2Module.h"
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"
4. Updated "CMakeLists.txt"
SHORT_NAME renamed to "my2", references within updated
MODEL_SOURCE added:
stdp_izh_bitwise_correct_connection.cpp
stdp_izh_bitwise_correct_connection.h
5. Updated "mymodule-init.sli"
name changed to "my2module-init.sli", references within/across files above
updated

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
<https://secure-web.cisco.com/1OkG_4Lw1yXYSv9Bo1mMO2W05lnXnEL03XeGcAPY__8APmBFD6LJj5zzZE42doCxkKRobTud5P4AT-oAs4WO_e4LtGvMBLDNRl2akKXbAPU8F8r9Rm4A-tpRybnnEUh062b56HNleUWk7QJ6N1WbDPtfI2tSIZfBrNSy7ZS4MsvzYfYHFlpG8GQQde5gApJecM5CFQEEP9CGymqYZ18LQ3zj1pcYeYG_L4XhXZhfL9be5WtSMrDZVy_ZeB0g3Qorb-lhDrLguvPgqUhCze8vfsqesaXfTpE3HtpsEMUcfd3Xc5vUP1KU6rRWzSAw8az7wM5CxmAlax7wYyP8eT_0bQAweIakbsUW3bXaCT9znQv15l-qoBLExOyTKQvbcyNiwLEBNflla-_MsLueEemTJ1NRiHSI7kGavYtpaKaeXtlSy7q0YU9lIMHnnS0AWr5keolzddt0U0uCpJmO2uL9FUA/https%3A%2F%2Fnest.github.io%2Fnest-simulator%2Fextension_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.
