#6 Segfault on parsing

[Pascal Heitz]

Hi,

I compiled polyworld successfully on Debian 7.5 with Mate environment and Qt 4.8.2.
But when running

./Polyworld worldfile

, i have randomly as a result:

worldfile.v2:2 Unexpected '54'

(30% of tries)
where 54 is the first word of the world file ("54 version\n")
or

Segmentation fault

(20%)
or

TSimulation/266: Error making run directory (17)

(50%)

I think its a bug somewhere in the parser. I hope you find the problem soon because I couldn't run it yet, and I would love to see your awesome work.

I also tried other world file, leading to the same result.

Cheers!

Actually the

TSimulation/266: Error making run directory (17)

comes from the fact that I made several tries per second, and since the run_###### directories are named by their timestamp, it cannot create 2 directories in the same second.

Hence their is actually only two issues which are the parsing error and the segfault. They occur with a 50%-50% distribution.

I can tell from that "54 version" line that you're trying to use an old worldfile. I'm sorry, I should just remove them, or put them in a directory clearly marked as out of date. You should be able to run Polyworld with an empty worldfile:

touch empty.wf
./Polyworld empty.wf

To see an up-to-date worldfile, you can look in sandbox. And to see all of the worldfile parameters you can look at the worldfile schema in etc/worldfile.wfs.
