octane demo not start under my osx Tweet

yeah, read the release notes, there's a link on the download page to them.
you need to install the cuda 3.0 drivers and cuda toolkit.

on 10.5 you also need to download and install XQuartz, as stated on the downloads page.

Thank you very much,radiance,but i know that on the 10.5.2 only work the x11 2.1.1...you think that with cuda drivers and tools octane is ready to roll?

yes, you need to install the cuda drivers and toolkit otherwise octane won't work.
read the release notes...

Ettore,
any reason why you're not running the last Leopard update (I think it was 10.5.8) on your Macs?
as for CUDA install, I don't remember having such a problem, I think I made a plain standard installation in my system HD... but I'm on Snow Leopard.
why are you talking about X11?

ciao,
Alessandro

As a lot of people i'm tryng osx;i'm from windows,and i don't want to come back.X11 and xquartz are the same thing?i have 10.5.2 and a laptop with 10.5.7.I have pain to make upgrade of the os...if octane run on 10.5.x,why on my system not work?In the utility folder i have x11,the info of the file says 2.1.1.

Hi, you need to click on your system harddrive as the destination, when installing the cuda drivers, and then install the cuda toolkit the same way.

Ettore,
as far as I can tell any free 10.5.x update should be safe (think about them as automatic update or Service Packs under Windows, while upgrading from 10.5.x to 10.6.x is like going from Vista to 7, for example). they are usually about bug fixes and better hardware/software driver and support (and much more, I know...)

you have not said what Graphic Cards you have in your Macs, that should help to see what's wrong.

another thing that come to mind is Uninstall the not-running previous Octane installation before installing CUDA drivers, then Toolkit and finally Octane demo.

EDIT: one more thing. after CUDA install you should see a CUDA preference button in "Preferenze di Sistema - Accessori" (see screnshot)

The stranhe thing is that i can't click on the destination;The window is like freezed.
I have an 8800 gts 320mb.The previous octane render is trashed,before i try with cuda install.

can you try maybe installing the cuda drivers/toolkit as an administrator account ?
(in your OS X user accounts, make your user an administrator)

this is very strange indeed! is it happening with CUDA install only? any chance you have run out of space or you accidentally marked your HD/partition as read only?
can you post a screenshot?

[radiance]

a screenshot would help

2.2 won't work.
please provide a screenshot of the problem of installing the cuda 3.0 drivers and toolkit...

I will post a scrrenshot,but believe me,it's the window of cuda installer that i can't select the destination.Some where i read that cuda 3.0 is for 10.5.7and up.I have 10.5.2.I will try on my laptop with 10.5.7.

it's not that we don't believe you...
I don't know since I switched to Snow Leopard before doing any CUDA installation, but what you said makes sense. if so you can try to ask at the nvidia forum: http://forums.nvidia.com/ - there's a "CUDA on OSX" section - or upgrade to 10.5.8 (maybe make a time machine backup before, if you're not sure)
