Setting up CUDA on Ubuntu 9.10

Download some stuff

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

Install the drivers

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 NVIDIA-Linux-x86_64-190.53-pkg2.run
## to start X up again
startx

Install the toolkit

sudo sh cudatoolkit_2.3_linux_64_ubuntu9.04.run

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

Install the SDK

Install and build the SDK

sudo sh cudasdk_2.3_linux.run
## 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
./bandwithtest

Help!

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
