Download the current Cuda Toolkit for Ubuntu and the GPU Computing SDK, and save the .run files somewhere.
Install and select gcc/g++ 4.4
sudo apt-get install \
gcc-4.4 g++-4.4 build-essential
sudo update-alternatives \
--install /usr/bin/gcc gcc /usr/bin/gcc-4.6 40 \
--slave /usr/bin/g++ g++ /usr/bin/g++-4.6
sudo update-alternatives \
--install /usr/bin/gcc gcc /usr/bin/gcc-4.4 60 \
--slave /usr/bin/g++ g++ /usr/bin/g++-4.4
Check with
sudo update-alternatives —config gcc
gcc —version
that you have now version 4.4.x of the compilers.
Install the nvidia drivers
sudo apt-get install \
nvidia-current\
nvidia-current-dev\
nvidia-current-updates\
nvidia-current-updates-dev
As root, run the two .run files from nvidia.
For compiling the SDK examples, you also need to install
sudo apt-get install freeglut3-dev libxi-dev
and create the following links
sudo ln -s /usr/lib/libXmu.so.6 /usr/lib/libXmu.so
sudo ln -s /usr/lib/nvidia-173/libGL.so /usr/lib/libGL.so
Then go to the NVIDIA_GPU_COMPUTING_SDK_... folder. In the file C/common/common.mk change the line
LINKFLAGS +=
to
LINKFLAGS += /usr/lib/nvidia-current
Then run make. This should compile everything, indicating that the CUDA stuff works.
