Building wxruby on windows with Visual C++ Express Edition

Hello,
Sorry for bothering You with so many questions, but I’m trying to build
wxruby from svn and wxWindgets 2.8.8 using Visual C++ 2008 Express
Edition.
I builded wxWindgets following instructions
http://wiki.wxwidgets.org/Compiling_WxWidgets and
http://wxruby.rubyforge.org/wiki/wiki.pl?HowToBuildWxWidgets
It compiled without any errors.
But on linking step of wxruby build process error occurs. May be another
compiler should be used or I missconfigured something?
Configurations that I’ve made: switched runtime library to
“Multi-Threaded (/MT)” for all projects and in ‘include/wx/msw/setup.h’
defined
wxUSE_UNICODE, wxUSE_GLCANVAS and wxUSE_GRAPHICS_CONTEXT to 1

Great - it would be good to have more people building from SVN on
Windows as though the platform’s used a lot, the development team are
primarily OS X & Linux based.

However, I’m pretty sure you can’t build wxRuby (or any other ruby
extension) with Visual Studio 2008. I’m assuming you’re using a ruby
installed from the One-Click or similar (you can check by doing ruby
-v). The released ruby builds are built with VS 6, and VS2008 can’t be
used to compile extensions for this. You’ll get the kind of weird errors
you seem to be getting.

You have two ways to get around this. You could try and get hold of a
copy of VS6, but Microsoft don’t make it available anywhere. I think I
may have tracked down a copy in my University Library.

What I would strongly recommend, though, is to look into using MingW -
which is gcc for Windows, and therefore free. It will soon be used as
the preferred compiler for Ruby, and wxRuby, on Windows. It takes
slightly longer to compile, but produces significantly faster-running
code.

Luis L. provides a handy start pack which includes a a Ruby built
with mingW, and the compiler.

Mario wrote a pretty comprehensive page about setting up wxRuby for use
with MingW, from installing MingW to compiling WxWidgets and wxRuby.
http://wxruby.rubyforge.org/wiki/wiki.pl?NotesOnMingW

Very happy to help further with this - might be more appropriate to
follow up on the -dev list if you want:
