Hi: this is a kind of follow-up to http://ask.sagemath.org/question/1576.... I have two Mac OS X 10.6.8 computers on which I have just installed SAGE v5.7. I have followed the accepted instructions on the above link and it all works fine on machine1, but when I go to run it on machine2 (irrespective of whether it is or is not still running on machine1) I get the screed of errors reproduced below (sorry but my low karma won't allow me to upload the file ...). Since I would like also to use this Dropbox facility on my university HP notebook with Windows 7 (using VM) I would love to know what basic step is missing from what I am doing, so that hopefully I can get it to work across all platforms smoothly.

Any help would be great thanks!!

Any solution to this? I have it working on 2 of 3 machines. But on the 3rd, I also get the "Directory not empty" error. I can't recall how I got it going on the 2nd one a while back.

I can't tell you where this error comes from, but i also got it when setting up syncing with Dropbox lately.

As was mentioned in this question Dropbox has a problem with symbolic links.

So I have come to a working solution for me by just symlinking the actual folder of my notebook files, which is /home/myname/.sage/sage_notebook.sagenb/home/admin in my case to a Dropbox folder

ln -s /home/myname/Dropbox/sage/admin/ /home/myname/.sage/sage_notebook.sagenb/home/admin

this done also on my laptop works very good for me. Don't forget to put the files from admin, which is also symlink in first place, into your Dropbox folder.

I have no idea about symlinks in mac os and I can't garantee for anything though.. Greetings, marv

And now it doesn't work any more?? :/. It was ok for about 2 days. I'm confused, sage planted some symbolic links in my dropbox folder

A while back somebody suggested setting the DOT_SAGE environment variable. Does anyone know if that works? I'd like to sync worksheets as well. And if Dropbox can't manage the syncing - is there another online resource which will?
