Riccardo,

I will rebuild in a minute. In the mean time I had added the update that was suggested by Sebastian.

This is the result of the execution:

address@hidden ~]$ openapp GWorkspace
2013-02-15 09:41:42.493 GWorkspace[1612] thumbnaildir: /home/edwin/GNUstep/Library/Thumbnails

To exclude permission problems I ran as root with the following result: 
address@hidden ~]$ su root

I also tried to remove the directory Thumbnails and run GWorkspace

It seems the directory has been created correctly.

Now I'll build the new version.
I'll report about it as soon as possible.

Kind regards

Hi,


It is, in frame 9, when initializing FSNodeRep, it tries to create the tumbnail directory, but fails,
and then terminates the application. So far, so good.
Question is, why it is failing.

Do you can add a NSLog output like this:
NSLog(@"thumbnaildir: %@", thumbnailDir);
To FSNodeRep.m right after the RETAIN (thumbnailDir); line around line 130.
Then recompile and check what's wrong with the dir?
At the locations something already exists, or wrong permissions prevent creating the directory?

Yes, that sounds like a good idea. The directory should be inside
"GNUstep/Library" in your home
does GNUstep/Library exist in your system? And if, is it writeable by your user? (not that accidentally it is root owned or such).

In any case the code in GWorkspace was brittle: NSSearchPathForDirectoriesInDomains returns a value, but it is not guaranteeed to exist and creating a directory won't create its parent.

I added a check, a creation and a new error log. Could you update GWorkspace from SVn and try it and see if it works and if it fails, what error you do get this time? Thank you.

Riccardo
