PREMAKE BUILD INSTRUCTIONS

 As of version 4.0, Premake is written in a mix of C and Lua. This mix
 enables many new features, but it makes building Premake a bit more
 complicated.
 
 If you downloaded a source code package from SourceForge, you will 
 find project files for Visual Studio, Code::Blocks, CodeLite, and
 GNU make in the build/ directory. Build the release configuration
 (the default for the makefiles) and you will find the executable in
 bin/release ready to go.
 
 If you want to use a debug build instead, or if you downloaded the
 source code from Subversion instead of a SourceForge release, read
 the next section for more information.
 
 Visual Studio 2002 and 2003 users: these version of Visual Studio 
 are unable to build Premake due to string size limitations. Use one 
 the newer, free versions of Visual Studio C++ Express instead.

 If you find all of this very confusing and need some help, see the
 end of this document for contact information.
 

GENERATING THE PROJECT FILES

 If you downloaded a source code package from SourceForge, the project
 files are already included (in build/) and you can skip ahead to the 
 next section. If you downloaded the sources from Subversion, you'll 
 need to generate new projects files before you can build. 
 
 In order to generate the project files, you need a working version of 
 Premake, either 3.x or 4.x versions, installed on your system. You can
 get it as source code or a prebuilt binary from the SourceForge 
 download page.
 
 Once you have a working Premake installed, use it to generate the 
 project files. For Premake 4.x, type a command like:
 
   premake4 gmake    -- for GNU makefiles using GCC
   premake4 vs2005   -- for a Visual Studio 2005 solution
   
 For Premake 3.x, use the old command line format:
 
   premake --target gnu
   premake --target vs2005
   
 Use the "--help" option to see all of the available targets.
 

RELEASE AND DEBUG BUILDS

 Premake can be built in either "release" or "debug" modes. You can 
 choose which configuration to build with the "config" argument:
 
   make config=debug    -- build in debug mode
   make config=release  -- build in release mode
 
 (IDEs like Visual Studio provide their own mechanism for switching 
  build configurations).
 
 In release mode (the default) you can build and run Premake like any
 other C application. In debug mode, Premake reads the Lua scripts from
 the disk at runtime, enabling compile-less code/test iterations. But
 it needs some help to find the scripts. 
 
 You can specify the location of the scripts in one of two ways: using
 the /scripts command line argument, like so:
 
   premake4 /scripts=~/Code/premake4/src gmake
   
 Or by setting a PREMAKE_PATH environment variable.
 
   PREMAKE_PATH=~/Code/premake4/src
   
 As you can see, you need to specify the location of the Premake "src"
 directory, the one containing "_premake_main.lua".
 
 
COMPILING SCRIPTS

 If you make changes to the core Lua scripts, you can integrate them 
 into the release build using the "compile" command:
 
   premake4 compile
   
 This command compiles all of the scripts listed in _manifest.lua into
 bytecode and embeds them into src/host/bytecode.c. The next release 
 build will include the updated scripts.
 
 
CONFUSED?

 I'll be glad to help you out. Stop by the main project website where
 you can leave a note in the forums (the preferred approach), join the 
 mailing list, or contact me directly.
