To use another language package in Voyager, you would need correctly compile the package,
which you've done already.
Then you need to create the DGDB (Dynamic Grammar Database) and SVDB (if you are using
Verification).
When you normally install Voyager the database is located in %VOYAGER%/db directory (where
%VOYAGER% is the environment variable denoting the directory where Voyager is installed).
You would find "dgdb-voyager" and "svdb-voyager" directory under normal installation.
You can delete these directories and recreate the database using the Nuance utility
"nuance-database-admin" which you can find under "bin" directory in nuance installation.
just run it with "-dbinteractive" switch and it would prompt you for all the parameters.
Once you have created the database you need to specify it in browser.conf
The location of these databases can be changed and specified to the Voyager through the
following params
scargs.sc.PrimaryDGDB=provider=fs,root=%VOYAGER%/db,name=voyager,class=dgdb
scargs.sc.PrimarySVDB=provider=fs,root=%VOYAGER%/db,name=voyager,class=svdb
The params here, specify "file" based database named "voyager" under %VOYAGER%/db directory.
This should do it for you.
