Re: [Tracker] Tracker-WARNING **: file is encrypted or is not a database

[Adrien Bustany <abustany gnome org>]

Hello Suparno!

Did you have a look at QSparql? It'll give you access to Tracker in a
much more Qt-ish way. In any case, you can have a look at the examples
for either library, that might help you get started:
libtracker-sparql (not so simple one):
http://git.gnome.org/browse/tracker/tree/examples/libtracker-sparql/async-connection.c
qsparql:
https://maemo.gitorious.org/maemo-af/qsparql/blobs/master/examples/sparql/simple/main.cpp

In your case, not sure why tracker_sparql_connection_get would fail...
What platform are you developing on? Are there special restrictions to
the DB access?

Cheers

Adrien
