I'm following this tutorial (https://www.digitalocean.com/community/tutorials/how-to-set-up-an-osrm-server-on-ubuntu-14-04) as good as I can, but I found some problems while trying to extract the map.

First, despite having created the symbolic links for profile and bin, it said Profile profile.lua not found! so I had to copy car.lua into osrm folder and rename it to profile.lua and the same for lib folder.

Then, the following error appeared:

[info] Input file: map.osm
[info] Profile: profile.lua
[info] Threads: 1
[info] Using script profile.lua
[STXXL-MSG] STXXL v1.3.1 (release)
[STXXL-MSG] 1 disks are allocated, total space: 4 MiB
[info] Parsing in progress..
[info] input file generated by Osmosis 0.43.1
[info] timestamp: n/a
PANIC: unprotected error in call to Lua API (attempt to index a nil value)

Any guess?
