[ANN] RubyInstaller DevKit 4.5.1 Released

Just in time for your holiday hacking, the RubyInstaller for Windows project [1] is pleased to announce its latest release of the DevKit [2] providing MinGW GCC v4.5.1 capabilities for Ruby on Windows users.

The DevKit is a powerful compiler toolchain focused on making it easy to use, build, and develop native RubyGems on Windows platforms. Since the DevKit is used to build the MRI-based RubyInstaller and it's required native dependencies, it's an integral component of the RubyInstaller project. Many RubyInstaller users have also discovered the DevKit is a useful toolchain for building other native projects on Windows.

While the DevKit will remain primarily a foundational build toolkit, expandable to meet your unique needs, it will continue to be enhanced for functional and ease-of-use reasons. Enhancements in this version include:

  * default toolchain is now TDM-based gcc/g++ v4.5.1
  * enhanced installation and upgrade behavior
  * easier 3rd party integration
  * initial support for JRuby cext (C-extensions) [3], [4], [5]
  * expanded core functionality (libtool, automake, mintty)
  * modularized build recipes for building TDM, TDM 64-bit, and LLVM-GCC Windows toolchains

...with the full list and usage instructions available at [6].

== QuickStart ==

After installing/upgrading [7] you may want to use a native RubyGem such as RDiscount. Simply type "gem install rdiscount --platform=ruby" and have at it.

Or you may want to build the latest EventMachine code from your cloned repo. A "rake -rdevkit clobber compile" from your repo root dir should get you going.

Or maybe you're developing a native RubyGem and want to manually build the native extension. Type "ruby -rdevkit extconf.rb" and you've got your Makefile.

Or maybe you'd like to try building another native package from source. Something like "c:\devkit\devkitvars.bat" (or "c:\devkit\devkitvars.ps1" for you PowerShell users) will bring all the DevKit tools onto your PATH, ready to help you build the code.

Or maybe you'd like to build [8] your own self-extracting DevKit, say an LLVM-GCC v2.8 32-bit version. No problem. Simply clone the RubyInstaller repo and...

C:\>git clone git://github.com/oneclick/rubyinstaller.git
C:\>cd rubyinstaller
C:\rubyinstaller>rake devkit sfx=1 dkver=llvm-32-2.8

However you decide to use the DevKit, we hope you find it makes your Ruby on Windows experience a lot more rewarding and productive.
