Lua compatibility issue [Documentation] about lua-rados HOT 4 OPEN

I think we can support 5.1 and 5.2, but I want to remain 5.1 compatible because LuaJIT only works with 5.1 (LuaJIT gets us to about 97% of the speed of C). Poking around a bit on the change log for 5.2 should reveal the parts that are different.

I had lua5.1 and 5.2 installed on my machine and we should make it a point to indicate what version of lua to be using with this project. I noticed you were using 5.1 a long time ago, but I left 5.2 sitting on my system. After I followed N's following insturctions:

• autoreconf -I m4 -ivf
• ./configure && make
• sudo apt-get install luarocks
• sudo luarocks install busted
• eval luarocks path
• export LUA_CPATH="$PWD/.libs/?.so;$LUA_CPATH"
• export CEPH_CONF=/path/to/ceph.conf
• busted test.lua
to build and test lua-rados. I had errors when I would try to run step 8. I then removed lua5.2 and started at step 3 and then I was able to get the test to run.

Do you have the errors handy from when you were running with lua5.2?

I don't but it was something like the following:

error loading module 'lfs' from file '/usr/local/lib/lua/5.1/lfs.so':
/usr/local/lib/lua/5.1/lfs.so: undefined symbol: luaL_register

In my case I believe 5.1 was replaced by 5.2

Ok, I think that rings a bell. I'll play with 5.2 tomorrow and see if I can make the code work with both versions.
