I am working on torch but when I try to run the following command:

require 'hdf5'

this returns the following error:

/home/mobeen/torch/install/share/lua/5.1/hdf5/ffi.lua:71: Unsupported HDF5 version: 1.10.0

The output of command apt-cache policy as shown:

mobeen@VIP-Ubuntu:~$ apt-cache policy gcc
gcc:
  Installed: (none)
  Candidate: 4:7.2.0-1ubuntu1
  Version table:
     4:7.2.0-1ubuntu1 500
        500 http://kr.archive.ubuntu.com/ubuntu artful/main amd64 Packages


mobeen@VIP-Ubuntu:~$ apt-cache policy g++
    g++:
      Installed: (none)
      Candidate: 4:7.2.0-1ubuntu1
      Version table:
         4:7.2.0-1ubuntu1 500
            500 http://kr.archive.ubuntu.com/ubuntu artful/main amd64 Packages

To my understanding this gives information about some package, that which version is installed and in the candidate, it means which version is going to be installed.

What I want to do is basically installed CUDA 8.0, which automatically installs gcc, but because of candidate version of gcc is 7.2.0, it installs this version. However, this afterwards gives compatibility errors.

In summary: I need to install a gcc version less than 5.

I am trying to install torch using the method described here: link.

The error I get is:

Error: Build error: Failed building.

I have installed gcc-4.8 using the command:

sudo apt install gcc-4.8

and then symlinked it by using the command:

sudo ln -s /usr/bin/gcc-4.8 /usr/local/cuda/bin/gcc
sudo ln -s /usr/bin/g++-4.8 /usr/local/cuda/bin/g++
sudo ldconfig

But still get the same error.

apt
