wxruby development - Nov 2008 - About graphics_ctx requirement, gem for ruby-1.9.1, and cross compiling

Hi,

I''d really like to start using wxRuby with ruby-1.9.1 on Windows. Here
are my feature requests by priority order :

1/ Currently, the build of wxRuby requires that the available build of
wxWidgets has graphics_ctx.
On Windows, this requires gdi+ support by wxWidgets and thus getting
gdi+ files, patching wxWidgets code ...

I wanted to build wxRuby trunk for ruby-1.9.1 on Windows.
I don''t use graphics_ctx in my application so the steps for supporting
gdi+ are a bit restrictive.
Can you consider removing this graphics_ctx requirement ?

2/ Otherwise, can you consider delivering upcoming wxRuby 2.0 gems for
ruby-1.9.1 on Windows ?

3/ Cross-compiling wxWidgets for Windows from Linux via mingw works well.
This seems not working with wxRuby.
To benefit from all the comfort of a *NIX system, it would be great if
cross-compiling is supported by wxRuby.

Cheers.

Great. I''ve just recently switched over development to target 1.9. It 
all works nicely, apart from Ruby''s dire performance with some methods 
on UTF-8 strings.

Yes, we could. Happy to have a look at it if you file it as a feature 
request.

As an alternative, I posted a pre-patched set of gdiplus headers and the 
dll to our website:

http://wxruby.rubyforge.org/GDIplus_for_mingW.zip

You should be able to just drop these into the MingW lib and include 
directories.

We''ll definitely have wxRuby 2.0 gems for both versions.  However at 
this stage it doesn''t seem that the rubygems developers have come up 
with a way of distinguishing 1.8 from 1.9 gems. I tried renaming the 1.9 
gems to wxruby_ruby19 but them gem install won''t find the gems for 
remote install. I''m looking into it

Possible, but I personally know very little about cross-compiling. It 
would mean another dev environment and set of rake scripts to maintain, 
and with a working set for four compilers already (gcc on 3 platforms, 
MSVC7.1 on Windows) I''m not that keen to take on another.

OK.
Do I still need to patch the wxWidgets src\msw\graphics.cpp file ?

If we can download the gem and install it locally (with -l flag), I
think that''s a suitable workaround.
