Error when compiling MyModule, the example extension module

by eben.cowley42＠gmail.com

Hi, I'm on Ubuntu 18.10 and I've successfully installed nest to `/usr`. I'm interested in writing my own synapse models and found these instructions for getting started: https://nest.github.io/nest-simulator/extension_modules The configuration step, `cmake -Dwith-nest=/usr/bin/nest-config ../MyModule` works fine. However, when I ran `make` I received the following compiler error: ``` ~/Projects/NEST/MyModule/mymodule.cpp: In member function ‘virtual void mynest::MyModule::init(SLIInterpreter*)’: ~/Projects/NEST/MyModule/mymodule.cpp:128:24: error: no matching function for call to ‘nest::ModelManager::register_connection_model<mynest::DropOddSpikeConnection<nest::TargetIdentifierPtrRport> >(const char [17])’ "drop_odd_synapse" ); ^ In file included from /usr/include/nest/kernel_manager.h:31, from /usr/include/nest/connector_base_impl.h:26, from /usr/include/nest/connection.h:29, from /home/ebanflo/Projects/NEST/MyModule/drop_odd_spike_connection.h:27, from /home/ebanflo/Projects/NEST/MyModule/mymodule.cpp:29: /usr/include/nest/model_manager.h:197:8: note: candidate: ‘template<template<class targetidentifierT> class ConnectionT> void nest::ModelManager::register_connection_model(const string&, nest::RegisterConnectionModelFlags)’ void register_connection_model( const std::string& name, ^~~~~~~~~~~~~~~~~~~~~~~~~ /usr/include/nest/model_manager.h:197:8: note: template argument deduction/substitution failed: make[2]: *** [CMakeFiles/mymodule_module.dir/build.make:63: CMakeFiles/mymodule_module.dir/mymodule.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:73: CMakeFiles/mymodule_module.dir/all] Error 2 make: *** [Makefile:152: all] Error 2 ``` I am not sure how to deal with this, and any help would be appreciated. Thank you!
