[OpendTect_Developers] OD_USER_PLUGIN_DIR/ OD_APPL_PLUGIN_DIR behaviour in 4.4

Wed Jan 9 17:17:53 CET 2013

Dear Antonio,

We have made some changes to the directory structure in OpendTect v4.4.
This also affected the usage of these two environment variables
OD_USER_PLUGIN_DIR and OD_APPL_PLUGIN_DIR.

Let me give some introduction first:
Whenever OpendTect is started, plugins can be loaded automatically. For
this OpendTect needs an 'alo' file, which lists the names of the plugin
libraries, and the library file itself.

OpendTect looks for plugins to load in two places:

- The installation directory ($DTECT_APPL)
- In your 'Personal directory' ($HOME/.od on Unix)

For both places, the alo files should be in plugins/$PLFSUBDIR and the
libraries in bin/$PLFSUBDIR
where $PLFSUBDIR can be lux32, lux64, mac, win32 or win64.

These two environment variables can be used to override the places where
OpendTect looks for plugins:

OD_APPL_PLUGIN_DIR:
Setting this variable overrides the loading of the plugins in the
installation, i.e. in $DTECT_APPL.

OD_USER_PLUGIN_DIR
Setting this variable overrides the loading of the plugins in your home
directory, i.e. in $HOME/.od. Plugins listed here will be loaded in
addition to the plugins in your OpendTect installation, or when set, the
plugins in $OD_APPL_PLUGIN_DIR.

As an example, if you have made a plugin for Linux64, and you want to load
these automatically for all users, you should set OD_USER_PLUGIN_DIR to say
/my_shared_disk/my_plugins

then add the alo files to /my_shared_disk/my_plugins/plugins/lux64
and add the libraries to /my_shared_disk/my_plugins/bin/lux64

Note that the above paths are as it should be. Currently OpendTect looks in
/my_shared_disk/my_plugins/lux64 (without bin/ ) for the libraries. This is
a bug and will be solved in the next patch release.

Best regards,
Nanne
