You will see in index.html a function called toggleData() that was
derived from the familiar data layer toggle. Move that code to
mapInit(). Or change the width of the "routingbar" div in index.html
to 30%.

In mapInit(), you will see a call to setMapExtent(). Replace it with a
call to setMapCenter(). You will need to create a LatLon object, but
there is a nice example just above it that handles the case when a
permalink is set.

It could be a bug in the demo.

Was the rebuild successful ? If you rebuild the planet, you will need
to increase MAX_NODES in libgosm.cpp to 23000000.

Can you do routing from the command line ? For example
QUERY_STRING="flat=45.303213&flon=-63.304713&tlat=44.6890011&tlon=-63.8092375fast=1&v=motorcar"
 ./gosmore

Did you install routing-instructions ? If not, remove it from gosmore.php

Debugging php can be difficult, but it's good experience.
