Description

LUA 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 must already be installed.
• Download Lua 5.0.3
• 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.
