Problem with installation

[bargoti]

While installing cutorch using luarocks I'm getting following error:

Warning: unmatched variable LUALIB

jopts=$(getconf _NPROCESSORS_CONF)

echo "Building on $jopts cores"
cmake -E make_directory build && cd build && cmake .. -DLUALIB= -DCMAKE_CXX_FLAGS=${CMAKE_CXX_FLAGS} -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="/home/ubuntu/torch/install/bin/.." -DCMAKE_INSTALL_PREFIX="/home/ubuntu/torch/install/lib/luarocks/rocks/cutorch/scm-1" && make -j$jopts install

Please help.

I have the same problem. I've tried out a few of the previous commits and the one from Nov 9th works for me (d41e2fd).

this should be a simple fix, we need to add guards around HALF random stuff for cuda 7.0.
cc: @killeent can you fix this.
