dia diagram 이 동작하지 않는다?

free software 인 dia 라는 다이아그램 툴이 있다. 개인적으로는 돈내고 살만한 가치의 무료소프트웨어인데...
어라...? 실행하면 실행안되고 실행환경?(정확하는 ) 인 xQuartz 만 뜬다.
확인해보니...

Dia Diagram Mac OSX Yosemite Fix

I use the Dia tool for all my diagramming work. I have worked with many tools, but find Dia the easiest to use and is the most responsive, apart from it being a great OpenSource tool :).

I recently upgraded to the new Mac Operating System Yosemite and I could no longer use Dia. Each time I clicked on the Dia icon, it would jump up & down and do nothing. I finally tried opening the app via the command line, which gave me the following error:

The domain/default pair of (.GlobalPreferences, AppleCollationOrder) does not exist

The error trace ended with GTK warning - could not open display.

I could not find anything on the internet that was Dia specific, so I thought of writing this blog, in hope of helping someone in the same situation as me. So here is what I did:

Goto your Applications directory where Dia.app exists (mine was located at: /Applications)
Right click the icon and click on Show Package Contents
Goto the directory Dia.app/Contents/Resources/bin
Edit the file dia, in your favourite text editor.
After line 39, add the line: export DISPLAY=:0
Save and exit.
Close XQuartz if its running.
Now Dia should come up.
If it does not come up, try restarting your computer.
If not, try and add the line - export DISPLAY=:0 to your ~/.bash_profile, re-login and hopefully you should have Dia working once again.

Let me know if this helped you out :)

아.. display 문제였구나.  큰 도움이됐다! 요세.. 말고 그 뒤의 운영체제에서도 잘 되는듯 하다. 어차피 해당 내용이 원인이라면 안되는게 이상할듯
