Hello everyone !


I try to install dijkstra.sql :

CREATE OR REPLACE FUNCTION shortest_path(sql text, source_id integer,
target_id integer,
                                         directed boolean, has_reverse_cost
boolean)
        RETURNS SETOF path_result
        AS 'MODULE_PATHNAME'
        LANGUAGE 'C' IMMUTABLE STRICT;

ERROR:  could not access file "MODULE_PATHNAME": No such file or directory

Can someone understand this error ? What is exactly this MODULE_PATHNAME ?

Thanks

Raphael
