Instructions to install a dirty buid of Weft-QDA on Mandriva 2006.0 (i586).
(20061122ber)

Installation instructions:
--------------------------
Make sure the following packages are installed.
E.g. use drakconf to install them from Mandriva mirrors for main and contrib:

	ruby-1.8.2-7.4.20060mdk.i586
	ruby-sqlite-2.2.3-1mdv2007.0.i586
	libsqlite0-2.8.17-5mdv2007.0.i586
	ruby-RubyGems-0.8.11-1mdk

Install ruby gem PageTemplates using the gem command line:
	gem install PageTemplate
	Successfully installed PageTemplate-2.2.3

Also the stdc++ library for gcc 3.3.6 is needed:
	libstdc++5-3.3.6-2mdk

As root install the contents of this tarball into /opt/, e.g.
	cd /opt
	tar -xvmjf /home/bernhard/weft-qda-20060mdk-ber1.tar.bz2
If you place it somewhere else, you must change the path in
the file run-weft-qda with an editor.

Create a symbolic link from /usr/local/bin:
	ln -s /opt/weft-qda-20060mdk/run-weft-qda /usr/local/bin/weft-qda

Now any user can just start it on the command line:
	weft-qda

Known problems:
---------------
Exporting does not work. It might be combination with PageTemplate-2.2.3.
See my question on http://rubyforge.org/mailman/listinfo/weft-qda-users.

Background or how and why was this dirty build produced?
-----------------------------------

The first approach is:
Installing the packages that come with Mandriva main and contrib.
Install ruby's PageTemplates and build wxruby 0.6.0.

Trying to run any wxruby application, e.g. 
	ruby wxruby-0.6-src/samples/controls/controls.rb
there is an error:
[..]src/wxruby.so: undefined symbol: _ZTV12wxRbListCtrl - [..]/src/wxruby.so (LoadError)

The error was reported on Fedora with gcc 4 as well, 
but the developers do not want to fix it.
http://rubyforge.org/tracker/index.php?func=detail&aid=2153&group_id=35&atid=218

Thesis: There is a difference between older g++ compilers and version 4.0.

Constructive proof:
	Fortunately Mandriva has a package for an old version of gcc as well.
	Install:
		gcc3.3-cpp-3.3.6-2mdk
		gcc3.3-c++-3.3.6-2mdk
		gcc3.3-3.3.6-2mdk
	Recompile wxruby with g++-3.3.6. 
		
	This alone produces more errors, probably because the binaries
	are incompatible.

	So rebuild wxGTK-2.4.2 as well and then rebuild wxruby again.
	To do this additionally install:
		libgtk+1.2-devel-1.2.10-41mdk

		export CC=gcc-3.3.6
		export CXX=g++-3.3.6
		#set LD_LIBRARY_PATH and PATH accordingly before 
		# building wxruby

	This build also has wx/html/htmlproc.h copied to the right place
	and the removal lines deactivated in extconf.rb.
