UPDATE!
i placed linkern.exe directly in the cygwin/bin dir and give --solver position the result is :

C:\Program Files\Inkscape>python\python C:\tspart.py --solver=c:\cygwin\bin\ C:\
dida1.pbm
Loading bitmap file C:\dida1.pbm ... done; 22293 stipples
Writing TSP solver input file C:\dida1.ol4o_b.tsp ... done
Running TSP solver ...
Traceback (most recent call last):

What was the name of the file in your C root directory that was generated? Was it a *.tsp file?

Did you get a *.svg file generated too, or just the TSP file?

Do the links on http://code.google.com/p/polargraph/wiki/TspVectorArtOnPolargraph shed any light on this (specifically http://www.evilmadscientist.com/forum/viewtopic.php?showtopic=4728)?

hi, i've tryed everything but nothing! the only things i had are tsp files and the errors reported in my second post.
tested all on windows xp and windows7...
about the errors, the last 2 words are "accesso negato" read "access denied" (i'm from italy!), but i changed properties of inkscape folder so everyone can read write and also placed all tsp pyton files in c:\tsp\ ...
any other idea?
thank you all for your time!

Copy your TSP python files to your root C directory. Ie... C:\

Switch over to C:\Program Files\Inkscape directory first.

Try running this command, without the extra parameters that you were running before:

C:\Program Files\Inkscape>python\python C:\tspart.py C:\dida1.pbm

If you still get access errors, that has to be some Windows access issue or something like that. Try running that command and see what you get.

Aha! Thanks for updating us Giorgio, I had got stuck on that too (using the path instead of the path+filename for linkern), but assumed I was doing something _else_ wrong!

Wow, that's kind of freaky seeing your posts in that thread Sandy from January. I came upon TSP on my own, and it still amazes me when life throws a coincidence like that at you 🙂

I really like your liberty picture posted in that thread!
