premake.lua

LUA programming language implementation (source code)

----------------------------------------------------
-- The main porpouse of this file is to build linux gcc makefiles.
-- Must have Premake version 3 installed.
-- Original Premake was changed to remove some parameters and add others.
-- Default parameters:
--   premake3s --target gnu --os linux
-- But it can build windows gcc makefiles, and visual studio projects.
--   premake3s --target gnu --os windows
--   premake3s --target gnu --os macosx
--   premake3s --target vs6
--   premake3s --target vs2002
--   premake3s --target vs2003
--   premake3s --target vs2005           (MUST UPDATE DEPENDENCIES)
-- In Linux the generated makefiles will not correctly build libraries in 64-bits.
--              must add "-m64 -fPIC" flags
