I followed nvidia official guide to install cuda-7.0, but I had a few problems they didn't provide a complete explanation. And my test samples cannot be built by make. I'll explain the several mistakes I found during the installation.

environment

I'm working on a 64-bit Ubuntu 14.04, with NVIDIA Corporation GK107 [GeForce GT 640 OEM] returned by lspci | grep -i nvidia. My gcc version is 4.4.7.

package

I downloaded from https://developer.nvidia.com/cuda-downloads the "Linux x86 -> Ubuntu 14.04 -> Local Package Installer", which it doesn't provide a md5 value to check. But later the installation was fine as it seems.

installation

I did:

sudo dpkg -i cuda*.deb # returned: OK
sudo apt-get update
sudo apt-get install cuda

test

As official guide said, I have to setup environment path first. I changed to:

cd /usr/local/cuda-7.0

and I can add path:

export PATH=/usr/local/cuda-7.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-7.0/lib64:$LD_LIBRARY_PATH

Here's the first problem: the path is lost whenever I close the terminal. Since I can check it with nvcc -V where we have nvcc under the first directory.

When I tried to compile the samples:

cd /usr/local/cuda-7.0/samples
sudo make

Finally it returned errors:

make[1]: entering directory `/usr/local/cuda-7.0/samples/2_Graphics/Mandelbrot'
/usr/local/cuda-7.0/bin/nvcc -ccbin g++   -m64      -gencode

/usr/lib/nvidia-346/libGL.so:‘_nv018tls’ undefined reference
...
# list of undefined reference

And I cannot go further.

other checks

  • cat /proc/driver/nvidia/version doesn't work since /proc/driver doesn't have the directory nvidia/.

  • /dev/nvidia* doesn't exits.

  • nvidia-smi command not found.

These problems exist after reboot.


some fixes

Fixed path and lib settings by adding those two lines under ~/.profile for current user:

export PATH=/usr/local/cuda-7.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-7.0/lib64:$LD_LIBRARY_PATH

And found a useful link: Installing and testing CUDA in Ubuntu 14.04 it seems I need to install by run file instead.

After several trials I finally found the solution. Installation of CUDA is a pain, for which keeps corrupting my system configuration that I have no way to revert.

The solution for the installation must be done in tty1 (the command line) mode, because it needs to kill GUI service before installing NVIDIA drivers, or it will refuse to work. And we need .run file. With reasons I can't know the .deb files never correctly configure themselves, and I never got them work. look Installing and testing CUDA in Ubuntu 14.04 for a similar solution.

Need to mention, according to my trails:

  • installation via apt cannot succeed.
  • installation via deb files cannot succeed.

I had the same problem. Running the following command helped me test and understand the problem:

ldd /usr/lib/nvidia-346/libGL.so.346.46

Finally, adding the following to my ~/.profile solved the problem:

export LD_LIBRARY_PATH=/usr/lib/nvidia-346:$LD_LIBRARY_PATH

as indeed the /usr/lib/nvidia-346 path was not given to the linker.

  • Can you write a more thorough answer that how did you find the problem out and when do we execute the commands chronologically? Then I might can change the accepted answer to this one. It's an old question, that some trivial I can't remember now. But I checked quick, in my laptop (we don't have CUDA, but have nvidia-*), dynamic lib path doesn't necessarily include /usr/lib/nvidia-*. – knh190 May 24 '15 at 16:52
  • The ld problem is reported during the compilation, but does your CUDA provides you /proc/driver/nvidia/version and nvidia-smi? That's the real problem, because these effects are global. You must need CUDA somewhere else. Will it work? Not only the samples? – knh190 May 24 '15 at 16:57

I too faced the same issue, on Ubuntu 14.04, x86_64 with cuda 7.5. The warnings were:

/usr/bin/ld: warning: libnvidia-tls.so.352.63, needed by /usr/lib/nvidia-352/libGL.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libnvidia-glcore.so.352.63, needed by /usr/lib/nvidia-352/libGL.so, not found (try using -rpath or -rpath-link)

This was the output of ldd /usr/lib/nvidia-352/libGL.so:

$ ldd /usr/lib/nvidia-352/libGL.so

I added the following line to ~/.zshrc (~/.bashrc...if you are using bash):

export LD_LIBRARY_PATH=/usr/lib/nvidia-352:$LD_LIBRARY_PATH

Thus, the following are the entries related to cuda in my ~/.zshrc:

export PATH=$PATH:/usr/local/cuda-7.5/bin
export LD_LIBRARY_PATH=/usr/local/cuda-7.5/lib64:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/usr/lib/nvidia-352:$LD_LIBRARY_PATH

Then I sourced ~/.zshrc

source ~/.zshrc

Now ldd /usr/lib/nvidia-352/libGL.so shows:

libnvidia-tls.so.352.63 => tls/libnvidia-tls.so.352.63 (0x00007f1617f1c000)

libXau.so.6 => /usr/lib/x86_64-linux-gnu/libXau.so.6 (0x00007f1614228000)
libXdmcp.so.6 => /usr/lib/x86_64-linux-gnu/libXdmcp.so.6 (0x00007f1614022000)

After this the make inside NVIDIA_CUDA-7.5_Samples directory completed successfully.

I had the same problem. I installed using the .deb package from nvidia website on Ubuntu 14.04. Solution for me was:

  • add export LD_LIBRARY_PATH=/usr/lib/nvidia-346:$LD_LIBRARY_PATH to ~/.bashrc
  • open terminal type:
  • cd to the samples folder
  • sudo bash
  • source ~./bashrc
  • check if /usr/lib/nvidia-346 is in LD_LIBRARY_PATH
  • make -j

This solved it for me.

I have the feeling, there are some permission issues when installing CUDA using the cuda-repo-ubuntuXXX_amd64.deb file. I have the
