12 months ago I don't have a Windows or Mac machine myself to test on, so starting the software there is unfortunately broken. Try opening the ltn executable inside the binaries folder -- does that do anything?

12 months ago Hi, Thanks for the quick reply. That’s what I did. Opened binaries folder, Ran ltn.exe
Terminal opened window as below

12 months ago Sorry, I'm not sure how to fix this without access to a Mac to try things out. This is an open source project; if anyone's reading this and can help get the Windows and Mac builds working better, help much appreciated.
In the meantime, stick with the web version: https://play.abstreet.org/0.3.48/ltn.html and let me know if you need a new area imported (not possible on the web version, unfortunately)

12 months ago OK, I’ll wait to see if the Mac download can be developed.
I am an elected borough councillor in Darlington and am working on filtering an area of Darlington called College.
I have attached a shot of the area hope that helps.

12 months ago I can at least get that area added to the web version today. The image in your email didn't come through to Github; does this cover it?

11 months ago I think I can reproduce this. The behaviour I find is:

@dabreegster Some ideas for longer-term fixes:
cwd is correct (See Mac/Linux https://stackoverflow.com/a/59916, Windows https://ss64.com/nt/syntax-args.html)cwd, rather than the binary location as the start point for its searchdabreegster

11 months ago Fantastic debugging + write-up, thank you!
We could improve the search for the data directory
https://github.com/a-b-street/abstreet/blob/f8e5d5f0a5f087f5038c309319ce9a50ac895a26/abstio/src/abst_paths.rs#L22 Rather than use the current directory as the base, we could try https://doc.rust-lang.org/std/env/fn.current_exe.html after stripping off the executable?
The variations of ../, ../../, etc in there are so that you can launch tools from different cases in the release binaries, from git, etc. For example cd abstreet/apps/ltn/src; cargo run would require us to find ../../data. Maybe there's a much saner way to do this though?
We could make the wrapper scripts more robust, by detecting their own location
This sounds useful. If somebody directly opens the exe, it'd still break, but be an improvement.
I have down loaded the software (for Mac) and run the ltn.exe I now have a terminal window open. what do I do next to get started?
