Secondo on Mac-OS Mojave: Installation Instructions

To be able to compile the Secondo database system, some tools and libraries must be installed. This document describes how to install all required tools.

Step 1: Installing xcode command line tools

open a terminal
enter the following line:
gcc --version

If the xcode tools are already present, the gcc's version is printed out. Otherwise a window pops up. Just click on install.

Step 2: Installing Java-SDK

open a terminal or use the one of the xcode installation
enter the following line
javac -version

If the Java SDK is already installed, the java compiler's version is displayed. Otherwise a browser is opened showing Oracle's Java download page. Accept the licence, download the latest SDK for Max-OS and install it.

Step 3: Installing the Berkeley DB

Secondo uses the Berkeley-DB as a storage manager. Thus, an installation of this tool is required. Because of licensing issues, this library cannot be distributed together with Secondo.

open a browser and navigate to the Berkeley-DB download page
download the db...tar.gz file of the latest Berkeley-DB version
this requires an Oracle account
if you don't have such account, just create it. it's for free
open a terminal and navigate to the folder containing the db....tar.gz archive
enter the following commands
(for other versions of the Berkeley-DB, just change the names in the first two commands):
tar -xzf db-18.1.25.tar.gz
cd db-18.1.25
cd build_unix
../dist/configure --prefix=$HOME/BDB --enable-cxx
make
mkdir $HOME/BDB
make install

Step 4: Installing SWI-Prolog

open a browser and go to the home of SWI-Prolog
click on Download → Swi-Prolog
click on Stable release
click on the MacOSX version to download the dmg file
open Finder, go to Downloads and double click on this dmg file
some time later, a SWI-Prolog icon is shown together with the application folder
drag the SWI-Prolog icon into the application folder

Step 5: Install further tools and set environments variables

open a terminal and navigate into a directory of your choice
download the required tools for Mojave
wget https://github.com/secondo-database/secondo-database.github.io/raw/main/files/Installation/Mac/SDK_OSX_MOJAVE.tar.gz
unpack the downloaded file
tar -xzf SDK_OSX_MOJAVE.tar.gz
change the directory
cd SDK_Mojave
run the installation script
./Install_On_Mojave
if applicable change your .profile file according to the instructions printed out during the installation process

Step 6: Compiling Secondo

open a terminal and navigate into the Secondo directory
cd $HOME/secondo
compile Secondo
make
Start Secondo according to the Secondo's User Manual
