Dear Stefan,

This looks like a version conflict between NEST and NESTML. In NEST 3.5 we have removed a number of aliases for built-in data types. It looks like your version of NESTML generates code that still relies on the old aliases.

There are two ways forward: Either install NEST 3.4, or get a newer version of NESTML. I don't know which version of NESTML you would need, hope Charl or Pooja can help.

Best,

Hans Ekkehard

Dear Charl,

many thanks for your help - it does indeed make sense and starts to compile now! After several days with struggle with NEST on cluster, I am also finally able to run the HPC version we have at LRZ.

However, there is another error occurring - which seems to do either with C++ NEST core or the compiler?

Hi,

My apologies for the confusing error message. It occurs because you have to explicitly tell NESTML which postsynaptic neuron type it is connected to in the simulation. You can see an example of that here: https://github.com/nest/nestml/blob/003d17a6425c3f8d88ed3aedd8d8e1d76245966e/tests/nest_tests/stdp_window_test.py#L58 The port is then assigned as "postsynaptic" and it is not considered for the error that you are seeing.

Please let me know if you run into any further trouble.

With kind regards,

Charl

Hello,

I am using an example synapse model which utilizes both post and pre spikes (nestml/models/synapses/stdp_nn_symm.nestml at master · nest/nestml (github.com)). 

I get an error: 

... 

 File "/dss/dsshome1/00/ge72puf2/.conda/envs/nest/lib/python3.8/site-packages/pynestml/codegeneration/nest_code_generator.py", line 469, in _get_synapse_model_namespace

    assert len(namespace["pre_ports"]) <= 1, "Synapses only support one spiking input port"

AssertionError: Synapses only support one spiking input port

It is confusing: can I or can I not use a model with 2 synaptic inputs (post and pre)? Is that a version thing?

Best regards,
