Tested with:
branch master: Ubuntu 18.04 and Red Hat Enterprise Linux Server 7.7 (Maipo), Python 3.7.3 and NEST Release 2.18.0
-
Install NEST following the instructions provided here (http://www.nest-simulator.org/)
-
Export an Environment Variable containing the installation directory of NEST. E.g.:
export NEST_INSTALL_DIR=$HOME/nest-simulator-install/
- Clone this GitHub Repository in a directory outside NEST source and build directories. E.g.:
cd $HOME
git clone https://github.com/alberto-antonietti/CerebNEST/
- Move to CerebNEST directory and create a new folder where you will build the extension module
mkdir $HOME/cereb-nest-build
cd $HOME/cereb-nest-build
- Run the following CMake command (Tested with CMake 3.2.2)
cmake -Dwith-nest=${NEST_INSTALL_DIR}/bin/nest-config $HOME/cereb-nest-build
The resulting output should be something similar to:
You can now build and install 'cerebmodule' using make make install
The library file libcerebmodule.so will be installed to /home/alberto/nest-simulator-install/lib/nest Help files will be installed to /home/alberto/nest-simulator-install/share/doc/nest
The module can be loaded into NEST using (cerebmodule) Install (in SLI) nest.Install('cerebmodule') (in PyNEST)
The module will be installed into a non-default location! Make sure to set the environment variables: export NEST_MODULE_PATH=/home/alberto/nest-simulator-install/lib/nest:$NEST_MODULE_PATH export SLI_PATH=/home/alberto/nest-simulator-install/share/nest/sli:$SLI_PATH [...]
- Execute the last two lines, generated by the CMake command.
export NEST_MODULE_PATH=/home/alberto/nest-simulator-install/lib/nest:$NEST_MODULE_PATH
export SLI_PATH=/home/alberto/nest-simulator-install/share/nest/sli:$SLI_PATH
This passage should be repeated every time the Terminal is closed. It is possible to add the two lines in your .bashrc to avoid doing this every time.
- Make and install the module
make
make install
- Every time you need the module, you can install it in this way:
python
import nest
nest.Install("cerebmodule")
- You can now use all the nodes and synapses contained in this NEST Module.
