This article describes how to install NVIDIA's GPU SDK "CUDA 5.0" on openSUSE 12.3.
Two workarounds are needed that are both related to the fact that gcc/g++ 4.7 is (yet) not supported by NVIDIA:
- for installing the kit
- for fixing the include files and compiling the samples
- have a GPU that is supported by CUDA
- have installed all packages needed for build
- have installed the nvidia-computeG0?, x11-video-nvidiaG0? and nvidia-gfxG0?-kmp-$flavour from ftp://download.nvidia.com/opensuse/12.3/
forcing installation of the toolkit
Download the CUDA 5.0 run file for openSUSE 12.1 (latest version available at the time of writing this) and run it like this:
bash ~/Downloads/cuda_5.0.35_linux_64_suse12.1-1.run -override compiler
That will make the installer ignore the compiler mismatch.
When asked for installation of the drivers answer *NO* as the available drivers in the SUSE repo above are already good enough (and are frequently updated by NVIDIA and tested by SUSE QA).
I have been using the default paths for installation. Depending on where *YOU* installed it you have to adopt the rest of the documentation below.
Set the library search path using
cat <<'EOF' > /etc/ld.so.conf.d/cuda.conf /usr/local/cuda/lib64 /usr/local/cuda/lib EOF
and update the library index using
patch the include and sample source
Then paste the following on console to fix the remaining incompatibilities:

This will *NOT* build simpleMPI unless you have manually installed mpicxx from 3rd party repos on your system.
To take advantage of a multi-cpu/multi-core system:
make -j $numberofcores -k
On a AMD FX(tm)-4100 Quad-Core Processor this decreased compile time down to 6 minutes (instead of 24 minutes).
