[pgrouting-dev] can not find the definition of the function

[Jinfu Leng]

Hello Jay,

Thanks very much.

You need to create a .sql file and write function definition.
I did not know how to create the .sql file. I added the definition of the
function:

CREATE OR REPLACE FUNCTION shortest_path_mild_two_q(sql text, source_id
integer,
        target_id integer, directed boolean, has_reverse_cost boolean)
        RETURNS SETOF path_result
        AS '$libdir/librouting'
        LANGUAGE 'C' IMMUTABLE STRICT;

to the file "rounting_core.sql".

Modify cmakelists accordingly.
Which cmakelists.txt file are you referring to? I updated the
cmakelists.txt file in the folder "core/src".

It is not working right now.
