Installing the CUDA toolkit results in the following instructions being printed to the console.
Please make sure your LD_LIBRARY_PATH
for 64-bit Linux distributions includes /usr/local/cuda-5.0/lib64:/usr/local/cuda-5.0/lib
OR
for 64-bit Linux distributions add /usr/local/cuda-5.0/lib64 and /usr/local/cuda-5.0/lib
to /etc/ld.so.conf and run ldconfig as root
The following code in /etc/profile
had no effect.
if [ -z "$LD_LIBRARY_PATH" ]; then
LD_LIBRARY_PATH=/usr/local/cuda-5.0/lib64:/usr/local/cuda-5.0/lib
else
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-5.0/lib64:/usr/local/cuda-5.0/lib
fi
export LD_LIBRARY_PATH
That is, rebooting and issuing echo $LD_LIBRARY_PATH
showed the variable was not defined.
To try the alternative suggestion, I added the two lines to the file /etc/ld.so.conf
so my file looks like this
include /etc/ld.so.conf.d/*.conf
/usr/local/cuda-5.0/lib64
/usr/local/cuda-5.0/lib
Then I issued:
sudo ldconfig
then
echo $LD_LIBRARY_PATH
Still the environment variable was not set. How do I comply with the CUDA installation instructions shown above?
