[2014-02-04 15:08:32] Unable to query CUDA driver version! Is an nVidia driver installed?

creating the nvidia device nodes manually may be required.

Thanks for a fast reply!!

I've already tried. With this configuration:

Code:

[root@fedora cudaminer]# cat ./nvidia_nodes 
#!/bin/bash
timestamp=`date`
modprobe nvidia-uvm

if [ ! -c /dev/nvidiactl ]
then
    echo "Server $HOSTNAME device files re-created at $timestamp"
    
    # Count the number of NVIDIA controllers found.
    N3D=`lspci | grep -i NVIDIA | grep "3D controller" | wc -l`
    NVGA=`lspci | grep -i NVIDIA | grep "VGA compatible controller" | wc -l`

    N=`expr $N3D + $NVGA - 1`
    for i in `seq 0 $N`; do
        mknod -m 666 /dev/nvidia$i c 195 $i;
    done
    mknod -m 666 /dev/nvidiactl c 195 255
else
    echo "Files exists"
    exit 1
fi

... and this result:

Code:

[root@fedora cudaminer]# ./nvidia_nodes 
Files exists

Anything else I could check?

Hi, I have a problem and I'm out of ideas of how to fix it. The cudaminer gives me this error:

Code:

[root@fedora cudaminer]# ./CudaMiner-master/cudaminer --help
	   *** CudaMiner for nVidia GPUs by Christian Buchner ***

[2014-02-04 15:08:32] Unable to query CUDA driver version! Is an nVidia driver installed?

I have CUDA installed:

Code:

[root@fedora cudaminer]# nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2013 NVIDIA Corporation
Built on Wed_Jul_17_18:36:13_PDT_2013
Cuda compilation tools, release 5.5, V5.5.0

And the Nvidia Driver updated:

Code:

[root@fedora cudaminer]# nvidia-settings -v
nvidia-settings:  version 331.38  (buildmeister@swio-display-x64-rhel04-15)  Wed Jan  8 19:53:03 PST 2014

I've already searched the forum and I'm sure I
- have correctly installed autoconf and automake
- first run autogen.sh, then configure and the make.
- have the path for CUDA to work correctly exported system wide

I've been dealing with this for more than a day so any suggestions are welcome!!

[ps]

Code:

[root@fedora cudaminer]# uname -a
Linux fedora 3.12.9-301.fc20.x86_64 #1 SMP Wed Jan 29 15:56:22 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
