Hello. I am trying to set up the popular deep learning library Torch7 on my
Windows computer. I have had a lot of trouble along the way but eventually
figured most of it out by googling. But now I'm totally stuck. I followed
the instructions here <http://www.thijsschreijer.nl/blog/?p=863> and set up
Lua and Luarocks from scratch, with Mingw. Everything worked fine and I was
able to install rocks, including ones which require compiling like
LuaSocket.
I followed the instructions on the Torch7 <http://torch.ch/> page to
install Torch via luarocks. But it fails building. I do not understand why.
Here is the console output. My best guess is that it has something to do
with `Building for: Visual Studio 9 2008` when I think I want it to use
Mingw.
PS C:\WINDOWS\system32> luarocks --server=

I don't know if this is an issue with torch or luarocks or something I did.
Any help would be greatly appreciated. I have been struggling with getting
this to install this for awhile.
