[Cartoweb-users] postGIS & dijkstra

[Sarawut Ninsawat]

Dear All

I think because at first time I complie dijkstra  without installation
of Boost dev and it might create a wrong dijkstra.sql without replace
of lib path.

Then after I install Boost dev and recomplie without clean the
dijkstra still did not replace with path.

Then I clean it and recomplie now everything is perfect.

Thank you

Sarawut
