Dear Sysadmins,
On macosx, some tests fail because it's not possible to create a temporary directory:
"Failedtocreatetemporarydirectory""/var/folders/Vz/VzBfKYBvEcmMWKvFIHB9q++++TI/­Tmp­"
Seehttp://slicer.cdash.org/testDetails.php?test=2915633&build=39626
Is there any configuration to change on MacOsx to allow the creation of directory in "/var/folders" ? Manually creating folder
like "/var/folders/Vz" also fail.
Thanks for your help,
Jc

Is there an env var that can be set to specify temp?

Hi Bill ­
Slicer uses Qt to get a temp path:
https://github.com/Slicer/Slicer/blob/master/Base/QTCore/qSlicerCoreApplication.cxx#L993
http://doc.qt.digia.com/4.7­snapshot/qdir.html#tempPath
On mac, this is no longer in /tmp, but is in the /var/folders
directory in an obfuscated path (which, BTW, is not deleted on reboot
­ I guess it's so mac apps can start up again where they left off).
On several macs that I use, the /var/folders directories for slicer
are always writable by the user running slicer. That's why I suspect
that slicer might have been run originally as root on this machine and9/19/12 Kitware Inc. Mail - Slicer factory - Write access to /var/folders/
https://mail.google.com/mail/u/1/?ui=2&ik=e554963425&view=pt&search=inbox&th=… 2/3
now regular users (or at least the nightly test user) can't update the
directory.
Best,
Steve

Seems other apps on the system have directories under /var/folders, but are owned by a specific user, not root.
There isn't a Vz directory that's owned by the kitware user, I suppose we can create the directory then change permissions. But,
shouldn't the directory been setup at some point?

Hi Folks,
Thanks for your help and comments.
Matt> I guess creating the "Vz" folder with the appropriate rights could be a good solution to help us moving forward. Would it be
possible for you to create such folder ?
I also found the following info regarding "/var/folder":

1. Run Disk Utility's permission repair to make sure ownership & permissions are correct on /var & its subfolders. Running Disk Utility's Verify Disk
   step is also
   good idea to make sure a file system error is not causing an issue.

Thanks Matt. The error related to tmp directory doesn't occur anymore.
