----------------------------------------------------------------
UFO is a portable distribution of LuaJIT (http://luajit.org),
that includes precompiled binaries for various platforms,
and FFI bindings for several open source (precompiled) libraries
----------------------------------------------------------------

Some of the bindings included are:
   OpenGL and glu, OpenCL, SDL, ZeroMQ, GLFW and others
      
To fire up quickly a sample, please do:
   ./luajit samples/intro.lua  (uses SDL)

To create a world-map .pdf, .svg and .png using cairo
   ./luajit samples/cairo/world-map.lua
   
Some more:
   ./luajit samples/glfw/moar.lua (uses OpenGL, glu, GLFW)
   ./luajit samples/AntTweakBar/simple.lua (AntTweakBar, others)
   ./luajit samples/AntTweakBar/OpenCL-info.lua
   ./luajit samples/OpenCL/info.lua

The most excellent sol's imgui implementation notes using SDL:
   ./luajit samples/SDL/imgui/ch01.lua
   ./luajit samples/SDL/imgui/ch02.lua
   ./luajit samples/SDL/imgui/ch03.lua
   ./luajit samples/SDL/imgui/ch04.lua
   ./luajit samples/SDL/imgui/ch05.lua
   ./luajit samples/SDL/imgui/ch06.lua

P.S.
   There are lot of un finished "objects": bindings, samples, 
platforms, etc.
   Hopefully I would never finish it :), as I would like this
experiment to be always work in progress.

use stable versions only

To make Lua, LuaJIT and UFO more popular use only stable versions of LuaJIT. Currently UFO Windows binaries has version of 2.1.0-alpha.

DevIL Examples

Hey,

do anybody maybe have an example for DevIL image loading? Would be awesome, because I can't get it to work. ⚡

And thanks for all the awesome examples already, I enjoyed to execute all one by one. :-D

Regards,
kung foo man

Add LuaSocket to the list of libraries

It would be great to have LuaSocket to be included in the list of libraries.

Update to LuaJIT-2.0.0

LuaJit is out of Beta, so maybe switching to the stable release would be appropiate. Cheers!

glfw input callbacks

Hi,

ufo seems like a great project. I have been fiddling around with glsw(on OSX) and I can set callbacks with ffi.cast (for example glfwSetCharCallback), but on input I get a segfault:

[...]
glfw.glfwSetCharCallback(ffi.cast("GLFWcharfun", function(w,c,a) end))

while glfw.glfwGetKey( window, glfw.GLFW_KEY_ESCAPE ) ~= glfw.GLFW_PRESS do
    gl.glClear( gl.GL_COLOR_BUFFER_BIT )
    glfw.glfwSwapBuffers(window)
    glfw.glfwPollEvents() 
end
[...]

Am I missing something?

Suggestion to build LuaJIT with Lua 5.2 features

I've recently begun using this incredibly useful set of tools for various programming endeavours; it's absolutely perfect for building a quick OpenGL demonstration.

The main issue I find with it is the lack of Lua 5.2 features, namely:

__len metamethod working on tables
__pairs and __ipairs metamethods

These features are not essential, but they are very convenient.
I also believe that any of the current code will be affected by the changes.

I've managed to compile LuaJIT x64 myself using the WinSDK, but it would be most helpful (for myself and others) if it were built with the flag by default.

Regal naming convention

Just a note to suggest naming the Regal libs as regal32.dll on Windows,
to correspond to the opengl32.dll naming scheme. Not a big deal,
if there is some other scheme you want to stick to.

Nigel

Add sqlite to the libraries list

Maybe use the one found in the wiki?

http://wiki.luajit.org/FFI-Bindings

Simple dll distribution on Windows and very useful.

samples/test.lua: The specified procedure could not be found.

Hey, i get this error for samples/test.lua:

C:\Users\Admin\Desktop\UFO>call luajit32 samples/test.lua

glBegin true    cdata<void *>: 0x00421375
glBegin1        false   samples/test.lua:111: cannot resolve symbol 'glBegin1':
The specified procedure could not be found.

glBegin2        false   samples/test.lua:112: missing declaration for symbol 'glBegin2'
glBegin true    cdata<void *>: 0x00421375
glBegin1        false   nil
glBegin2        false   nil

Edit: too fast, that's a forced error...

-- Print error messages
print('glBegin',  pcall(function()return ffi.cast( "void*", gl.glBegin  )end))
print('glBegin1', pcall(function()return ffi.cast( "void*", gl.glBegin1 )end))
print('glBegin2', pcall(function()return ffi.cast( "void*", gl.glBegin2 )end))

zlib.lua fails on Linux

Probably others do as well, but I needed a complete FFI interface to zlib and found this one.

The problem is in the ffi.load line:

local zlib = ffi.load( ffi_zlib_lib or libs[ ffi.os ][ ffi.arch ] or "z" )

It should be:

local zlib = ffi.load( ffi_zlib_lib or libs[ ffi.os ] and libs[ ffi.os ][ ffi.arch ] or "z" )

The problem should be obvious from the fix (libs[ffi.os] not defined thus it crashes trying to access libs[ffi.os][ffi.arch]).

SDL Binding Error

Using the SDL module fails with these messages on OSX Lion.

luajit[71964] <Error>: kCGErrorInvalidConnection: CGSGetCurrentCursorLocation: Invalid connection
luajit[71964] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
luajit[71964] <Error>: kCGErrorInvalidConnection: CGSGetCurrentCursorLocation: Invalid connection 
luajit[71964] <Error>: kCGErrorInvalidConnection: CGSNewWindowWithOpaqueShape: Invalid connection
luajit: C++ exception

It errors as soon as I call SDL_SetVideoMode.

lua_getupvalue does nothing

Hi when I call lua_getupvalue, nothing gets pushed onto the stack. I wrote a test program below showing the problem, the code works with the ordinary lua 5.2.1. I built the latest luajit under linux.

How to run on Anroid device? Do I need rooted device? I have tried to make bin/Anroid/arm/luajit executable, but it says Operation not permitted. So I need to package it to .apk and then install it? I would like to reside samples or my code on SD Card outside Anroid installation Anroid/obb and Anroid/data, because I can't edit files there from non-rooted device, only through PC as USB-Flash.
