Ugly (jagged) arcs (caused by locale setting)

[VlasovLabTech]

Why arcs are so terrible?

[jcoffland]

This does not look right. Did you make any code changes in order to get it to compile in Ubuntu 15.10?

[hyOzd]

I'm seeing the same thing. Linux Mint here. No code changes.

I also had some strange results with the 3d results, maybe its related. I will try to post a screenshot tomorrow.

[jcoffland]

@hyOzd Are you using an official release or one you built from source?

[hyOzd]

I've built from git source.

[VlasovLabTech]

No changes. I followed the instruction step by step ( "sudo apt-get update", "sudo apt-get upgrade" before it).

[jcoffland]

If you run camotics from the command line do you see any errors or warnings? I'm running pretty much the same code and I don't see this problem.

[hyOzd]

@jcoffland in my case I don't see any warnings or errors.

[VlasovLabTech]

there are no errors.

Same problem here with 1.0.4 & 1.0.6 (both installed from your .deb) on Ubuntu 14.04

[misan]

Adding terminal output just in case is useful for diagnosing the problem:

[jcoffland]

I think I solved it. Does the problem go away if you run like this?:

LC_NUMERIC=C camotics

In fact, if I force a locale that uses commas instead of periods in numbers I get the same messed up arcs you are seeing. This was actually already fixed in the source code. Future versions of CAMotics wont require manually setting the locale.

If this doesn't work then run locale -a and make sure it lists C as one of your system locales.

[misan]

Exactly, using it as you suggest arcs look perfect. It is solved for me.

Thanks a lot.

[jcoffland]

Awesome! Glad we finally figured it out. Thanks for being persistent. This locale problem has caused a lot of problems I should have suspected it sooner.
