title: Can't install a cuda-accelerated library (GPU-LIBSVM)
body: <p>I'm trying to install the cuda-accelerated library found on this website : <a href="http://mklab.iti.gr/project/GPU-LIBSVM" rel="nofollow">http://mklab.iti.gr/project/GPU-LIBSVM</a></p>
  
  <p>I downloaded the linux makefile and executable and tried to follow the readme file :</p>
  
  <blockquote>
    <p>Instructions to compile Linux GPU-Accelerated LIBSVM</p>
    
    <ol>
    <li>Install the NVIDIA drivers, CUDA toolkit and GPU Computing SDK code samples. You can find them in:</li>
    </ol>

    2011)</p>
    
    <p>You may need some additional packets to be installed in order to
    complete the installations above.  Please refer to the web for more
    details.</p>
    
    <ol>
    <li><p>Copy this folder to "/NVIDIA_GPU_Computing_SDK/C/src"</p></li>
    <li><p>Use the Makefile found in "/NVIDIA_GPU_Computing_SDK/C"</p></li>
    <li><p>Find the "svm-train-gpu" executable in /NVIDIA_GPU_Computing_SDK/C/bin/linux/release</p></li>
    </ol>

  <p>But i could not find the "NVIDIA_GPU_Computing_SDK" folder, even after upgrading cuda to 5.5 (wich should contain the SDK). It seems that this instructions are outdated. So I copied the folder into "opt/cuda/src/" and used this makefile :</p>
  
  <pre><code>EXECUTABLE  := svm-train-gpu
  CUFILES     :=
  CU_DEPS     :=
  CCFILES      := svm-train.c svm.cpp 
  CUDACCFLAGS     := -po maxrregcount=16
  USECUBLAS       := 1
  include ../../common/common.mk
  </code></pre>
  
  <p>It first told me it could not find "common.mk", so I found in my disk an other common.mk file from an other CUDA project implementation called "common-gcc-cuda-4.0.mk" wich is described in the header as a "Common build script for CUDA source projects for Linux and Mac platforms" and tried again.</p>
  
  <p>Now I have this error :</p>
  
  <pre><code>$ make
  make: *** No rule to make target `makedirectories', needed by `bin/linux/release/svm-train-gpu'.  Stop.
  </code></pre>
  
  <p>Can anyone help me please ?</p>
