Dear Willem,

NEST requires LTDL to handle dynamic modules. Without it, Install is not available. If you cmake NEST with the default options, LTDL should be included, unless cmake does not find the library—take a look at the cmake output.

Another point is that, as Pooja pointed out, we have modified the module configuration recently. Major modernizations are still in PR stage (see #3064) but if you should run into problems with loading, maybe try to go back to the 3.6 release.

Best,

Hans Ekkehard

Subject: [NEST Users] Re: SLIInterpreter --> Key '/Install' does not exist in dictionary

Thanks Pooja! However, the problems appears also with nest 3.6 and 3.5. The file 'nestml/tests/nest_compartmental_tests/compile_test.py’ reproduces the problem for me, no matter the nest version apparently. Are there any specific C++ libraries that need to be installed for the loading to work?

Best regards,

Willem

Hi Willem,

There are some known issues with the NEST master and NESTML after the model registration is changed in NEST. There is a bug opened for this on the NEST repository: https://github.com/nest/nest-simulator/issues/3064

This is currently being worked on in NEST (see here). The corresponding changes in NESTML are also in progress (see here). Until they are fixed, I think it is safe to use NEST 3.6 for generating code with NESTML.

Hope this helps!

Regards,

Pooja

Dear all,

I’m trying to run nestml with the latest nest master branch commit (8e85268ca512e0f509240fb5ef06f62a4e61a67e) but I get an error when calling the `nest.Install()` function.

Did anybody experience the same problem, or know what might cause it?

Best regards,

Willem
