Downloading and Installing Exodus
Mac OSX 64bit Snow Leopard Installer http://exodusdb.googlecode.com/files/exodus-11.5.28-osx-installer.app.zip
C++ Compiler
If you want to write or compile Exodus programs you must install the XCODE gcc C++ compiler. You don't need a C++ compiler to just use the Exodus command line to access the database or run prepackaged Exodus programs.
XCODE is available in the OSX dvd in the utilities folder.
Postgresql
If you want to use Exodus to provide multivalue database functionality then you must already have or install a PostgreSQL database.
http://www.postgresql.org/download/macosx
Postgres does not have to be on the same server as Exodus, however, if it is not, dictionary entries cannot call Exodus subroutines.
By default, Exodus assumes the following postgres configuration. This is very convenient for quick setups but of course is not secure.
host=127.0.0.1 port=5432 dbname=exodus user=exodus password=somesillysecret connect_timeout=10
The following Exodus command creates the default database and password. It also configures postgres to use the exodus plugin for sort/select on dictionary entries. It requires a postgres admin user and password to do so.

Using Exodus
Look your Applications folder for Exodus or just use the unix console.
Try the following commands.
| Command | Comment |
|---|---|
| EDITING AND COMPILING | |
| edic hello | edic=edit+compile+catalog. Creates a skeleton hello.cpp file using nano editor. edic will only compile on exit if saved, so make some change before you exit. |
| hello | Run it |
| compile hello | compile without editing |
| edic testsort | Browse a sample exodus program showing all fundamental database operations including dictionaries and list. |
| compile testsort | compile the preinstalled test program |
| testsort | Run it to generate some data and inspect the output |
| DATABASE OPERATIONS | |
| listfiles | quick tool avoiding need to use any database client |
| list myclients | text output - no page/column headers just yet sorry |
| list myclients {H} | html output (port of a fully blown LIST replacement in heavy production use since 2000) |
| list dict_myclients | NB the underscore after "dict" is *required*. "dict(SPACE)myclients" wont work |
| list dict_voc | if you understand this then you understand your pick |
| edir myclients SB001 | you can edit data or dictionaries directly. edir="edit record" |
| delete myclients SB001 | useful command line tool |
| createfile tempfile | ditto |
| deletefile tempfile | ditto |
| createindex myclients CLIENT_TYPE | speeds up select commands on the indexed fields in the traditional way |
| deleteindex myclients CLIENT_TYPE | filenames are case insensitive, keys and fieldnames are CASE SENSITIVE |
If you get the following error then you have not completed the installation of the Exodus plugin for Postgres.
PGRES_FATAL_ERROR: ERROR: function exodus_extract_text(bytea, integer, integer, integer) does not exist
