Hello All, 

I use Mnemosyne w/ a custom datadir kept in Dropbox.

I do it this way because the Mnemosynes I am trying to sync are on different operating systems on the same computer, Mac OS X & Linux. (I perceive that this hinders me from setting up a sync server.)  

I have been able to do this by installing Mnemosyne on Mac OS X using the Linux version & setting up a plist that, upon login, will launch 

  mnemosyne -d ~/Dropbox/Mnemosyne 

(Like its behavior in the Mnemosyne.app version, but w/ the custom datadir.)  

But when I launch Mnemosyne in Linux after using Mnemosyne in Mac OS X, two dialogues appear. 

First dialogue: 

    Unable to load file: database version mismatch.

Second dialoge: 

    Creating temporary database. 

Mnemosyne then creates a ___TMP___ database w/ nothing in it. I am currently forcing Mnemosyne to open my cards in Linux by:

    rm ~/Dropbox/Mnemosyne/config

What I Would Like to Know

1) Why is this happening? 

2) If there are any workarounds that will stop this from happening, what are they & how are they done? 

Thank you so!

Hi,

Both for sync and for dropbox you need the same versions of the Mnemosyne on the 2 computers.

Unfortunately, this is complicated by the fact that the OSX version lags a couple of releases behind the Windows/linux version, but Patrick is working on a fix for that.

Kind regards,

Peter
