The binary or the whole folder? And can you open gedit and turn line numbers on and see what line 259 says. I check my own and they don't say the same thing as your Windows error did.

I put all my py files in the Concorde folder, cd to Concorde, copy a pbm to Concorde, and run the terminal command from there. And it works. Linkern binary is the only thing I moved to usr/local/bin.

I'm only using the concorde and the linkern files. Did not install Concorde itself in Ubuntu. Haven't checked to see if I can (but betcha it's possible). I agree the gedit will show line numbers, but notepad won't in Windows. Haven't checked since you originally asked, but before doing all that, I guess I will have to install Concorde for Linux and give that a whirl.

I compiled Concorde in Ubuntu, no problems.

./configure

sudo make

You took the source and compiled? All I did was download the concorde.gzip and linkern.gzip files and moved them (lots of places now; lol). Now each is an executable but when I try to double-click on either I get (now I temporarily moved both files to my desktop in Ubuntu) this error. Maybe I'm going to have to download the source files and manual compile it myself in Linux (never done it for this program; did have to compile MAZE5 which used it's own special compiler and it was a pain). Or, maybe, I'll just stick with the convoluted flow that I've done so in Windows and be done with it (very tired now; caused my insomnia last night, but at least I finally got a result before hitting the sack; lol). Again, I appreciate your help Mahvin. Maybe that's why yours work and mine don't. The thread implied that all I had to do is download these two programs and all is well with the world. I know that isn't so though. lol

That's not what I was discovering when reading. For Windows, yes, you are correct, but not so for Linux. It recommended compiling Concorde. Get some sleep, attack tomorrow!

lol; you're right. Now if I run it in Windows these two files (in cygwin directory) it just gives parameters to follow. Compile Concorde; cost/benefit analysis time now. lol

Well, I finally figured out a good way to take the resulting SVG file (using G'MIC's morphological filter) and get a decent path off of it without using Inkscape.

I have yet to play with the file in Inkscape, btw. Something tells me you'd be able to make some interesting pictures using Inkscape's path effects.

I can imagine you could.

Excellent colorized version Mahvin. Figured out a few more tricks (still work) but got the result much smoother now (still using Potrace for the cleanup step). Figure I would include the TSP file too. Until I figure out how to create Organic Labrynths, I will create many more of these (but not necessarily post them here; you all probably are getting tired of them anyway; lol).
