[redland-dev] Error on Initializing Redland Libraries

[Michael Szalay]

Hi all

I'm new to the librdf libraries.
In my program, I try to initialize a triple store like this:

   rdf_world = librdf_new_world();

    //set logger
    librdf_world_set_logger(rdf_world, NULL, (void *) log);

    //open
    librdf_world_open(rdf_world);
    log4c_category_log(get_category(), LOG4C_PRIORITY_INFO, "Configured 
world.");

I get the following error when I call librdf_world_open:

raptor_sequence.c:125: (raptor_free_sequence) assertion failed: object 
pointer of type raptor_sequence is NULL.
[stdout] INFO     tripleStore.server - TripleStore said: 
rdf_query_rasqal.c:1207:librdf_query_rasqal_constructor: fatal error: 
failed to initialize rasqal
librdf fatal - rdf_query_rasqal.c:1207:librdf_query_rasqal_constructor: 
fatal error: failed to initialize rasqal

I'm using raptor-1.4.18, rasqal-0.9.16, redland-1.0.8.

Any help whats going wrong here?

Thanks Michael
