Cannot render osm file -- FORG0001: Cannot convert string to double: ""

[ballsystemlord]

Hi, I had to increase the memory limits for java, aside from that I did not change the program a bit.

0 make

An inspection of map.svg yielded that it is mostly empty (BTW: The gawk cmd is printing only lines that contain more than spaces or nothing at all to a new file (map2.svg), from map.svg):

% gawk '{ if($0 ~ /^ *$/){ next; } print $0 }' map.svg > map2.svg
% ls -l map*
-rw-r--r-- 1 me me 1248581516 Jun  5 18:25 map.osm
-rw-r--r-- 1 me me     175824 Jun  5 19:38 map.svg

-rw-r--r-- 1 me me      37588 Jun  5 21:07 map2.svg

The map2.svg file is so small that I'm including most of it here:

<?xml version="1.0" encoding="UTF-8"?>

   <g>
      <polyline class="route train" points=""/>
   </g>
   <g>
      <polyline class="route train" points=""/>
   </g>

The "route trains" sections continue till the end of the file. That is, the file does not have the valid ending tags, or any ending tags for that matter, it just ends.

Thank you
