OTOY Forums

Moved away from Windows/Maxwell due to extremely slow render speeds & just fed up of Microsoft OS continual crashing etc etc. Have had mint running nicely now with Blender & thought I'd go spend my cash & get Octane. Have downloaded latest Linux demo version from the web site, have gone through the CUDA installation & Nvidia driver updates as per...

http://www.noobslab.com/2012/06/nvidia- ... n-for.html

I've also made sure that libstdc++ is running higher than 4.1.2

Getting all excited ready to play with Octane - I go to the executable "octane" & it doesn't want to open, it does nothing. So I then pull up a terminal & run ./octane to see if that starts it off but only to be greeted with...

./octane: error while loading shared libraries: libcuda.so.1: cannot open shared object file: No such file or directory

Ran a locate to see where things were installed...

/usr/include/linux/cuda.h
/usr/lib/libicudata.so.48
/usr/lib/libicudata.so.48.1.1
/usr/lib/nvidia-current/libcuda.so
/usr/lib/nvidia-current/libcuda.so.1
/usr/lib/nvidia-current/libcuda.so.295.40
/usr/lib32/nvidia-current/libcuda.so
/usr/lib32/nvidia-current/libcuda.so.1
/usr/lib32/nvidia-current/libcuda.so.295.40
/usr/share/gtksourceview-2.0/language-specs/cuda.lang
/usr/share/gtksourceview-3.0/language-specs/cuda.lang
/usr/src/linux-headers-3.2.0-23/include/linux/cuda.h
/usr/src/linux-headers-3.2.0-23-generic/include/linux/cuda.h

But that's it, being a Linux driver for 2 months that's me sort of hitting a brick wall now, phew so glad I didn't purchase the software first & decided to test it.

Has anyone got any suggestions or do I have to go build up a windows box now & reinstall maxwell render to get this new project finished - fingers & toes crossed I don't have to, would so like to get Octane going

Many thanks in advance

libcuda seems to be installed in a non-standard location. You can run octane like this: If you can't get it working, uninstall the driver you got from noobslab and get one from here: http://www.nvidia.com/Download/index.aspx?lang=en-us

Hi Yah Roland,

chae@chae-desktop ~ $ LIBRARY_PATH="/usr/lib/nvidia-current/:$LD_LIBRARY_PATH" ./octane
bash: ./octane: No such file or directory
chae@chae-desktop ~ $

Forget the above forgot to go to the folder the octane file was in...

tried both lib & lib32 both with the same error...

Just downloading the latest drivers as per link above, will let you know how I get on...probably by the time this all takes I could have my Windows box up & running

I made a typo, the command line should be --

You need to install an NVIDIA driver driver and a CUDA toolkit. libcudart comes with the toolkit, so make sure you install it. You can get it from here: http://developer.nvidia.com/cuda-toolkit-40 .

Hi Yah Roeland,

I was nearly ready to down load LuxRender to give it ago...luckily during the time I was reading all their blurb, I had uninstalled the nvidia drivers, cuda, bumblebee etc, rebooted & then reintalled the latest nvidia drivers from the PPA Repository, then downloaded the Cuda Toolkit again, did another reboot to be on the safe side & yeah Octane pulled up first time - Now a happy chappy

Will have a quick play with Blenders Exporter to Octane & if happy then I'll go organise a license

Regards from Auckland

Not sure what's happening with Octane now but this is getting so frustrating.

Decided this morning to start work on a clients project, nothing has changed since I installed & went through all of the above posts. Import my obj, nothing shows up in the render view. I then notice that Octane doesn't see my Cuda device !!!! It seen it yesterday but why not today,

Reinstalled the CUDA drivers & then did a reboot, graphics card showed up

I hope I don't have to do this all the time?

Another question is there any way of increasing the GUI fonts size, I find that on my graphics settings (auto res for the nvidia driver) some of the areas are extremely hard to read or somewhere where you can change the font style.

Regards

Chae

No you can't. Im not a Mint user but you must check cuda toolkit. If you first time installed cuda toolkit from repo you must uninstall then reinstall version 4. 0. 17 and set cuda path - see the cuda insteller message in the terminal.
