Surprisingly, the proprietary Nvidia driver doesn’t bring in the SDK required for compiling modules (unlike the OpenCL stuff, which is apparently something Nvidia does, but doesn’t like to speak about).

Installing on Linux :: RPM

First steps from the Linux install document from Nvidia would be :

# uninstall previous cuda-repo-fedoraXX rpms - Nvidia hasn't figured out Fedora numbering yet
yum localinstall <download-directory>/cuda-repo-fedora20-6.5-14.x86_64.rpm

Unfortunately, the RPM method doesn’t ‘respect’ bumblebee, so need to install manually (without new Nvidia card drivers from RPM directly).

Installing on Linux :: RUN

Download the ‘Run’ version rather than the ‘RPM’ one :

# NB: It's large! ::  972,320,904 Nov 24 16:48 cuda_6.5.14_linux_64.run
cd <download-directory>
chmod 700 cuda_6.5.14_linux_64.run 
./cuda_6.5.14_linux_64.run 

# to use more recent compiler ()
./cuda_6.5.14_linux_64.run --override

Do you accept the previously read EULA? (accept/decline/quit): accept
Install NVIDIA Accelerated Graphics Driver for Linux-x86_64 340.29? ((y)es/(n)o/(q)uit): n
Install the CUDA 6.5 Toolkit? ((y)es/(n)o/(q)uit): yes
Enter Toolkit Location [ default is /usr/local/cuda-6.5 ]: 
Do you want to install a symbolic link at /usr/local/cuda? ((y)es/(n)o/(q)uit): y
Install the CUDA 6.5 Samples? ((y)es/(n)o/(q)uit): y
Enter CUDA Samples Location [ default is /root ]: 
Installing the CUDA Toolkit in /usr/local/cuda-6.5 ...
Missing recommended library: libGLU.so
Missing recommended library: libXmu.so

Installing the CUDA Samples in /root ...

Finished copying samples.

===========
= Summary =
===========

Driver:   Not Selected
Toolkit:  Installed in /usr/local/cuda-6.5
Samples:  Installed in /root, but missing recommended libraries

Please make sure that
 -   PATH includes /usr/local/cuda-6.5/bin
 -   LD_LIBRARY_PATH includes /usr/local/cuda-6.5/lib64, or, add /usr/local/cuda-6.5/lib64 to /etc/ld.so.conf and run ldconfig as root

To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-6.5/bin
To uninstall the NVIDIA Driver, run nvidia-uninstall

Please see CUDA_Getting_Started_Guide_For_Linux.pdf in /usr/local/cuda-6.5/doc/pdf for detailed information on setting up CUDA.

***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 340.00 is required for CUDA 6.5 functionality to work.
To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file:
    sudo <CudaInstaller>.run -silent -driver

Logfile is /tmp/cuda_install_2542.log

Finishing up

Better ld.conf approach for Fedora, as root :

echo "/usr/local/cuda-6.5/lib64" > /etc/ld.so.conf.d/cuda.conf && ldconfig

And for the user that needs to use the compiler & other tools, edit ~/.bash_profile :

# add (before the export PATH): 
PATH=$PATH:/usr/local/cuda-6.5/bin
