Actually, that's not entirely correct.... while the documentation
shows it as a reference variable, it's not actually required to be a
pointer. And in either case, the OP had the error code returned
(127), and $retval would have nothing to do with causing the error.
What I would recommend trying is:
<?php
exec('./gpsbabel -p "" -r -t -i gpx -f "test.gpx" -o kml -F
"test2.kml" 2>&1',$ret);
print_r($ret);
?>
On a side note, I'm curious as to what 'gpsbabel' does. I've
worked a bit with Keyhole markups and GIS overlays, etc. Neat stuff.
