CUDA fresh installation - missing libraries

Hi!

I installed today the CUDA toolkit (pacman -S cuda). Now, when trying compile something that uses cuda I am getting failure:

$ g++-5 -lpthread -lcuda
/usr/bin/ld: cannot find -lcuda
collect2: error: ld returned 1 exit status

I even try to add symbolic link into /usr/lib, but it doesn't helps. What can I do more?

Re: CUDA fresh installation - missing libraries

Try using 'ld-config' to refresh the database and see if that helps.

Re: CUDA fresh installation - missing libraries

You can also try passing it --verbose to get some more info.

"ld -lcuda --verbose"

Re: CUDA fresh installation - missing libraries

command: ld -lcuda --verbose returned a lot of data, but I think that at last is important.

attempt to open /usr/x86_64-pc-linux-gnu/lib64/libcuda.so failed

ld: cannot find -lcuda

paths are wrong, but:

[mik@mik-pc ~]$ cat /etc/ld.so.conf
#
# /etc/ld.so.conf
#

include /etc/ld.so.conf.d/*.conf

# End of file
[mik@mik-pc ~]$ ls /etc/ld.so.conf.d/

/opt/cuda/lib64
/opt/cuda/lib
/opt/cuda/nvvm/lib64

ld-config command is known for me and already executed.
Please see - ldconfig can see cuda library:

Re: CUDA fresh installation - missing libraries

cuda install its binary in the /opt directory.

The bin file there in critical and you need to add it to your path.

# Add nvcc from /opt/cuda/bin to PATH
if [ -d "/opt/cuda/bin" ]; then
    export PATH="/opt/cuda/bin:$PATH"
fi

Sorry, don't know how to do code blocks in this forum.

Welcome to the forums.  Watch the dates -- I hope this is not still an issue some six years later.
