SDK in Linux

  Hi all:

      First I need to state I'm a green hand to Linux.

      My system is Ubuntu 10.4. After I downloaded the SDK, in the NBody directory for example, I typed " make", then I go to the debug directory, I typed "./NBody", but I get the following information:

./NBody: error while loading shared libraries: libGLEW.so: cannot open shared object file: No such file or directory

  Can anybody help me?

   Thanks a lot.

install libglew1.5 with command

sudo apt-get install libglew1.5

you may need install other libs as well. just search it in synaptic manager.

 Thank you nou:

     I did, including libglewmx1.5,glew-utils,libglewmx1.5-dev, libglew1.5-dev. Now I meet the following problem:

     Failed to load kernel file : /home/yang/Desktop/ati-stream-sdk-v2.2-lnx64/samples/opencl/cl/app/NBody/build/debug/x86_64/NBody_Kernels.cl
      What can I do ?

  Thanks a lot!

  Hi nou:

     I copied the kernel to the executable directory and succeed running the NBody sample.

  As a Linux beginner, it really took me a long while to run the SDK sample. Now I am trying to use all my two HD5970s to do calculation. Any sugestions?

   Again thank you very much for your patience.

you must have configured Xserver to use both GPU. did you run aticonfig --initial --adapter=all you can check /etc/X11/xorg.conf if there are two Device section.

then you must select both cores with export DISPLAY=:0 default it is :0.0 which select only first core. :0.1 select only second core.

 Hi nou:

      Can you give me the exact codes? ( as I'm a newbie of linux)  I typed "aticonfig--initial--adapter=all " and get this:

      aticonfig--initial--adapter=all: command not found.

 Also I want to share my test results: when I remove the ribbon between the two HD5970s I can found two GPUs, when I connect them ( and I enabled crossfire in windows and restarted in Linux) I can only find one GPU. Shall I remove the ribbon?

    Thanks again.

Sorry for the late reply. Can you confirm the problem persists with latest 11.2 driver?

This can be used to install it properly https://help.ubuntu.com/community/BinaryDriverHowto/ATI

The steps to be followed after catalyst installation are

aticonfig --adapter= all --initial -f

I hope it helps.

Thanks
