Hi,

We are moving some applications from Perl to Lua and we would like to use RRDtool with Lua.

It seems RRDtool is supporting Lua as long as a valid lua interpreter is found during configure step. Question:
can I re-use whatever LuaJIT which comes with OpenResty or do I really need to compile Lua 5.2 and build
after that RRDtool ?

Anyone here using RRDtool with OpenResty/Lua ? Any pointers, experiences ?

Many thanks,
Stefan

Couple of things for anyone ready to play with rrdtool and lua:

1. Get lua 5.1. Lua 5.2 will not work with RRDtool since some calls have been replaced from main
    library, example: lua_call

2. You can use the distribution packages or compile your own. Make sure if you compile
    and build LUA yourself you will enable dynamic shared libraries for LUA. Default
    LUA is building the only a static lib

3. luajit is not compatible with rrdtool's configure script. It will not correctly detect nor will
    it work.

Now, this will come as a problem if one is trying to use RRDtool + openresty. Would be good to see some integration between the
two, probable the simplest way will be RRDtool will support luajit. Its configure script expect lua 5.x :(
