Lua 5.1/5.2 supported?

[vkee]

Is Lua 5.1/5.2 supported? I updated to that from the default installed with Torch for other packages and it seems to have broken torch-ros.

Hi Vincent,

I have not yet tested with Lua 5.1/5.2 - probably it is not working out
of the box. I guess there could be some minor differences between the
luajit ffi and the facebook luaffifb
(https://github.com/facebook/luaffifb) and I am not sure if there is an
equivalent of the lua bit operation module (http://bitop.luajit.org/)
for Lua 5.1/5.2. What error messages are you seeing? Is torch7 itself
still working correctly?

Torch7 itself works fine for me.

The error comes up when I try to make a publisher.
This is the error message.
