I tried to reinstall torch, nn and cutorch (luarocks install torch ecc), as suggested on other issues, but even if they don't have any problem, cunn installation give me the same error.
Any suggestions? Thanks in advance
Lorenzo

hey Lorenzo,

It looks like you are missing THCGenerateFloatTypes.h: No such file or directory
this points to the fact that you have an outdated cutorch.
Maybe the outdated cutorch is in some unexpected location on your machine and is being picked up by cmake.

I'd suggest first running: https://github.com/torch/ezinstall/blob/master/clean-old.sh

then: luarocks install cutorch
and then: luarocks install cunn

Solved, the issue was the same as: torch/cutorch#592
