Description
-----------
[LUA](http://www.lua.org/) is a powerful, fast, lightweight, embeddable scripting language.
Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode for a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping.
Instructions for Mac OS X
-------------------------
- [swig](swig "wikilink") must already be installed.
- Download [Lua 5.0.3](http://www.lua.org/ftp/lua-5.0.3.tar.gz)
- Untar lua-5.0.3.tar.gz into a folder of your choice
- Edit the file *config*. In particular you need to uncomment the following lines to enable dynamic loading of libraries.
`LOADLIB= -DUSE_DLOPEN=1`
`DLLIB= -ldl`
- Further set the installation prefix in *config* if you don't like the standard path.
- Run
`make && make install`
- Lua executable, libraries and headers are now installed.
### Set CMake paths
- Set environment variables if you didn't use the standard path, e.g add the following lines to the *.profile* file in your home directory, if you installed Lua to *$HOME/local/lua-5.0.3*
`# add lua to PATH`
`export PATH=$HOME/local/lua-5.0.3/bin:$PATH `
`export CMAKE_LIBRARY_PATH=$HOME/local/lua-5.0.3/lib:$CMAKE_LIBRARY_PATH `
`export CMAKE_INCLUDE_PATH=$HOME/local/lua-5.0.3/include:$CMAKE_INCLUDE_PATH`
CMake is now able to find Lua.
