[OpendTect_Developers] OD_USER_PLUGIN_DIR/ OD_APPL_PLUGIN_DIR behaviour in 4.4

[Corrao Antonio]

Dear all,
I have begun porting my own plugins to opendtect 4.4.
In our deployment configuration we use OD_USER_PLUGIN_DIR/ OD_APPL_PLUGIN_DIR a lot to keep many configurations available at the same time.

Now, examining 4.4 release, my question is: does the OD_USER_PLUGIN_DIR work as in 4.2?
I noticed that now plugins libraries are under bin/lux64 whereas the .alo files are in a different location (in version 4.2 the directory plugin directory contained the .alo and a lib directory with the .so files).
I tried arranging the plugin libraries and .alo the same way I did with 4.2 but it does not seem to work any more.
Browsing the documentation it seems that you must put all the libraries in the bin/lux64 dir, and keep just the alo files under the plugin directory; quoting from the online help:

"The publishing and distribution of OpendTect plugins is pretty straightforward. The .alo files can be installed in the plugins/platform ($DTECT_APPL/plugins/$HDIR) directory, while the actual plugins (the .DLL, .so or .dylib files) go in the normal bin sub-directory"

So is it true that if I want to make my own plugin autoload it must be placed in the program bin directory? Usually that is not possible as the permissions do not allow me to write there.
Also, copying my libraries into that directory is not advisable (keeping stuff separate helps when you manage multiple releases of your own plugins).
I used the previous directory environment variables OD_USER_PLUGIN_DIR/ OD_APPL_PLUGIN_DIR to make  users see different subsets of the plugins, or even different releases of the same.
Now it seems that all libraries must reside in bin/lux64.

Thank you very much.

Best regards,
AC
