qtbindings
----------
This project provides bindings that allow the QT Gui toolkit to be used from the
Ruby Programming language. Overall it is a repackaging of a subset of the KDE
bindings ruby and smoke systems into a format that lends itself well to
packaging into a Ruby gem.
Goals
-----
1. To make it easy to install a Qt binding for Ruby on all platforms using
RubyGems
2. To maintain an up-to-date binary gem for Windows that is bundled with
the latest version of Qt from http://qt.nokia.com
3. To reduce the scope and maintenance of the bindings to only bind to the
libraries provided by the Qt SDK.
4. To increase compatibility with non-linux platforms
Tested Environments
--------------------
Mac OSX 10.6.8 (Snow Leopard)
XCode 3.2.6
Brew - QT 4.8.2
Cmake 2.8.6
Windows XP SP3
QT Libraries 4.8.3
Mingw 4.4
Cmake 2.6.4
Ruby 1.8.7p370 and 1.9.3p0 installed from rubyinstaller.org
Note: Ruby 1.9.3 patch levels 125 and 194 on Windows have a bug in the I/O
system which prevent the usage of the pos method. That is why I'm using 1.9.3p0.
See http://bugs.ruby-lang.org/issues/6179 and http://bugs.ruby-lang.org/issues/6401
Ubuntu Linux 11.10
QT SDK 4.8.1
Cmake 2.8.5
Compiling
---------
Compiling qtbindings requires the following prerequisites:
1. cmake 2.8.x installed and in your path
2. QT 4.8.x installed and in your path
3. Ruby installed and in your path
4. gcc 4.x
Additionally: all of the operating system prequisites for compiling,
window system development, opengl, etc must be installed.
Rakefile
--------
Perform the following steps to build the gem on Unix or Mac:
1. rake VERSION=4.8.x.y gem
Where the x is the subversion of QT and y is the patch level of qtbindings
Perform the following steps to build the gem on Windows:
1. Ensure you are running Ruby 1.8.7
ruby -v #=> ruby 1.8.7
2. rake distclean
3. rake build
4. Switch to Ruby 1.9.3
ruby -v #=> ruby 1.9.3
5. rake build
6. rake VERSION=4.8.x.y gemnative
Where the x is the subversion of QT and y is the patch level of qtbindings
Note: The gem is built twice to create the FAT binary which will work
on both Ruby 1.8 and 1.9. The Windows utility called pik is useful for
switching between Ruby versions.
After building the gem, verify the examples work by running:
1. rake examples
Operating Systems Notes:
Debian Linux
------------
1. The following should get you the packages you need:
sudo aptitude install build-essential bison openssl libreadline5
libreadline-dev curl git-core zlib1g zlib1g-dev libssl-dev vim
libsqlite3-0 libsqlite3-dev sqlite3 libreadline5-dev libreadline6-dev
libxml2-dev git-core subversion autoconf xorg-dev libgl1-mesa-dev
libglu1-mesa-dev
Mac OSX Snow Leopard
-----------------------
1. XCode
2. Brew (http://mxcl.github.com/homebrew/)
Install qt with 'brew install qt'
Windows - Note: Only necessary for debugging (binary gem available)
--------
1. mingw from the Qt SDK in your path: ie C:\Qt\2010.04\mingw\bin
Install
------
On linux/MacOSX you must make sure you have all the necessary prerequisites
installed or the compile will fail.
gem install qtbindings
This should always work flawlessly on Windows because everything is nicely
packaged into a binary gem. However, the gem is very large ~90MB, so please
be patient while gem downloads the file.
