This is my own personal build system. You probably are here because you need this to build one of my projects.

Dependencies

  • LuaJIT

apt-get install luajit or brew install luajit tends to do the trick.

Usage

After installing LuaJIT, do this:

git clone https://github.com/rweichler/aite
git clone https://github.com/rweichler/MY-OTHER-PROJECT
cd MY-OTHER-PROJECT
luajit ../aite/main.lua

Installation (optional)

Just make a symlink to main.lua in your $PATH:

ln -s /some/directory/aite/main.lua /usr/local/bin/aite

Then you can just run aite to start a build.

Compatibility (host)

  • Mac
  • iOS (jailbreak required)
  • Linux
  • Windows 7 (MinGW needs to be installed)
  • FreeBSD

Available targets

  • Whatever the host is
  • iOS (if on Mac)
  • 3DS homebrew (if on Mac/Linux)
  • Wii homebrew (if on Mac/Linux)

WTF is how2build.lua?

its basically Makefile. heres an example:

function default()
    local b = builder()
    b.compiler = 'gcc'
    b.build_dir = 'build'
    b.src = {'main.c'}
    b.output = 'a.out'
    b:link(b:compile())
end

Check out the examples folder for more.

Also, can have multiple functions in there, for different stuff. You'd call it with aite function_name. aite by itself translates to aite default.

Documentation

Using builder

local b = builder()
  • b.compiler (string): e.g. 'gcc' or 'clang'
  • b.src (table): The source files you'll be compiling. e.g. {'main.m'} or fs.scandir('*.m')
  • b.build_dir (string): The folder where you want all the ugly .o files to go. e.g. 'build'
  • b.output (string): Where the executable should go. Add .dylib or .so or .dll to the end to make a dynamic library.
  • b.defines (table): What you want #defined at compile time.

Advanced ones:

  • b.linker (string): The linker. If this isn't set, it will use b.compiler.
  • b.include_dirs (table): the folders you wanna include from (like rpetrich's iphoneheaders or something)
  • b.library_dirs (table): the folders you wanna look in for libraries.
  • b.libraries (table): the libraries you want to link to.

Convenience functions

Let's say you're trying to build some monolithic codebase with a bunch of nested C++ files in one folder, and then a random other file, and then just the top-level contents of some random directory.

b.src = table.merge(
            fs.find('nested_folder', '*.cpp'),
            'random_file.cpp',
            fs.scandir('some_other_folder/*.cpp')
        )

os.pexecute is exactly like os.execute but it also prints out the command, like with Makefiles.

os.capture is like os.execute, except that it returns whatever the command prints out as a string.

Add TIME_IT = true to the very top of your file in order to print out how long your build took.

Caveats

In order to make how2build.lua nicer to read, I have opted to not have file dependencies (other than mapping source files to object files, and object files to binaries)

What I mean by this is, let's say you have a file lol.c and lol.h. The c file #include's the h file. If you change the h file, then the c file will not be recompiled. The only way the c file will be recompiled is if you edit the c file.

Mitigating this

  • run touch lol.c after editing lol.h.
  • if more than one file depends on the .h file (and touching them all would be a pain), then run touch how2build.lua. That will cause a complete rebuild.

Making jailbreak tweaks

Builder

local b = builder('apple')
  • b.frameworks (table): Public/Private Apple frameworks you want to link with. e.g. {'Foundation', 'UIKit', 'AppSupport'}
  • b.archs (table): table listing of the archs you want to use. e.g. {'armv7', 'arm64'} or {'x86_64'}
  • b.sdk (string): name of the SDK you wanna link against. e.g. 'iphoneos' or 'macosx'
  • b.sdk_path (string): Optional. The full path to the iPhoneOS8.1.sdk (or whatever), in case if you don't have Xcode.

Remember to have b.output be something that ends with .dylib. And you probably want to link with libsubstrate.dylib too.

Debber

Create it using this:

local d = debber()
d.input = 'layout' -- folder where the "layout" of the deb will be
d.output = 'package.deb' -- self-explanitory
d.packageinfo = { -- equivalent of the DEBIAN/control file
    Name = 'Yeee',
    Package = 'yee.yee.yee',
    Version = '1.0',
}
d:make_deb()

Calculate the md5sum, size, etc so you can put it in your repo and print it out like this:

d:print_packageinfo()

Note this must be done after making the .deb, because the md5sum and size are dependent on it.
