Setting up CUDA on Ubuntu 9.10

  1. Download some stuff
  2. 1)Developer drivers
    2)CUDA Toolkit
    3)CUDA SDK code samples

    from NVIDIA.

    In my case I grabbed 190.53 drivers, 64 bit CUDA Toolkit for Ubuntu 9.04, and the CUDA SDK code samples.

    Note: most of the CUDA SDK stuff doesn’t work out of the box with gcc 4.4 yet, so use 4.3.

    sudo apt-get install gcc-4.3 g++-4.3

    You may have to update the symlink /usr/bin/gcc to point to gcc-4.3.

    Some other libraries you may need:

    sudo apt-get install libxi-dev libxmu-dev freeglut3-dev

  3. Install the drivers
  4. You will have to drop out of X to install the drivers, note the command to start X back up if you don’t know it..

    ## to stop X
    service gdm stop
    sudo sh
    ## to start X up again

  5. Install the toolkit
  6. sudo sh

    Modify your environment as it suggests, for example I added the following to my ~/.bashrc file:

    export CUDA_BIN="/usr/local/cuda/bin"
    export PATH=$PATH:$CUDA_BIN
    export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64

    Source your bashrc to make the changes active, or open a new terminal.

    source ~/.bashrc

  7. Install the SDK
  8. Install and build the SDK

    sudo sh
    ## cd to your NVIDIA_GPU_Computing_SDK/C
    sudo make

    Test it out, there should be a bunch of executables in created in the bin subdirectory..

    cd bin/linux/release

  9. Help!
  10. Some errors you may encounter.

    ## missing glu.h
    sudo apt-get install freeglut3-dev

    ## gcc: error trying to exec 'cc1plus'
    ## if you installed gcc 4.3 but not g++ 4.3 this may happen.
    sudo apt-get install g++-4.3

    ## /usr/bin/ld: cannot find -lparamgl
    ## /usr/bin/ld: cannot find -lrendergl
    ## these are built as part of the CUDA SDK
    ## cd to your NVIDIA_GPU_Computing_SDK/C
    sudo make

    If you are seeing errors that resemble the following, they may be caused by having gcc/g++ 4.4.. install 4.3

    error: inline function ‘void* memset(void*, int, size_t)’ cannot be declared weak
