install torch on fedora 25

[Viktor Füvesi]

Hi Everybody!

I have tried to install Torch on my Fedora 25 distro.
I used the same dependencies list as on fedora 24.
During the installation i got some errors:

Building on 4 cores
-- Found Torch7 in /root/torch/install
-- MAGMA not found. Compiling without MAGMA support
-- Automatic GPU detection failed. Building for common architectures.
-- Autodetected CUDA architecture(s): 3.0;3.5;5.0;5.2;6.0;6.1;6.1+PTX

etc

I know fedora 20, ..., 24 are supported by Torch. Has somebody idea how to fix problem of the installation in my case? Or I have to go back to fedora 24 to use torch in native mode.

What do you think about the Docker packages? I like use cutorch, indeed.

Thank you for your help!

Best regards,

Success!

Here is the process to install torch and its deps on fedora 25:

2016.12.05.

• install negativo17 repo:
• dnf config-manager --add-repo=http://negativo17.org/repos/fedora-nvidia.repo

• install nvidia driver and cuda:
• http://negativo17.org/cuda-8-cudnn-nvidia-drivers-and-gnome-software-metadata/

• install gcc-4.9.2 with devtools:
• http://unix.stackexchange.com/questions/293743/install-another-gcc-version

• install torch:
• http://torch.ch/docs/getting-started.html#_
• I used the same deps as it was on fedora 24.
  

Have fun!

Best regards
