SPARQL isn't a software but a specification that has multiple implementations. Tracker has its own SPARQL parser and implementation, but there are others too. Tracker's can be found in libtracker-data If you mean QSparql then: http://maemo.gitorious.org/maemo-af/qsparql > Is there any more dependencies?? > > Thnks > Suparno > > -----Original Message----- > From: Adrien Bustany [mailto:abust...@gnome.org] > Sent: Friday, August 05, 2011 12:28 PM > To: Suparno Bose (WT01 - Manufacturing & Hi Tech) > Cc: tracker-list@gnome.org > Subject: RE: [Tracker] Tracker-WARNING **: file is encrypted or is not a > database > > If you can compile a Qt app with your tools, you should be able to compile > QSparql as well :) > > On Fri, 5 Aug 2011 11:49:41 +0530, suparno.b...@wipro.com wrote: > > Adrien. > > Actually am working on Automotive linux platform .
