wxruby development - Nov 2008 - Build problem with ruby-1.9.1-preview1

Hi all,

I wanted to have a look at wxRuby on a recent version of ruby 1.9
(ruby-1.9.1-preview1) on Ubuntu 8.10 x86.
Here is the result :

I have buillt successfully wxRuby with ruby-1.8.7p72 and ruby-1.9.0-4.
So this seems to be a problem with this more recent version of ruby 1.9.
I found that rubyio.h  is located in a ''backward'' folder
inside the
ruby 1.9 include.

Cheers.

Thanks for the report. I''ve also been tracking ruby-1.9 with wxRuby not
had any problems, but I haven''t tried with 1.9.1. This is my version 
which works:

Abaddon:~ alex$ ~/bleed/bin/ruby -v
ruby 1.9.0 (2008-10-04 revision 19669) [i386-darwin9.5.0]

I''ve filed this a bug, must fix for 2.0,

Some notes on my configuration :
- I''ve built and installed SWIG 1.3.35 with the default options
- I have installed ruby-1.9.1 with the program suffix 19.
Thus I can switch easily from ruby 1.8.7 to ruby 1.9.1 by just
appending 19 to all ruby related commands (ruby19, gem19, rake19).
I''ve already done that when I tried ruby-1.9.0-4 with wxRuby.

With the modifications between ruby-1.9.1 and ruby-1.9.0-4, do you
think that I have to install ruby-1.9.1 with the default name (i.e.
ruby and not ruby19) wrt to SWIG ?

Cheers.

No, SWIG doesn''t care what ruby version you have installed, or even 
whether you have it installed it all. Our rakefiles at some points 
naively do `ruby ...` to call ruby scripts, but the behaviour of those 
scripts shouldn''t vary by ruby version.

It seems to be down to two changes in ruby 1.9.1

1) rubyio.h has been removed (in favour of ruby/io.h), so SWIG''s 
generated code is now wrong. This is only properly fixable by a patch to 
SWIG, but we can add a temporary workaround in our SWIG-fixing rakefiles.

2) Our own typemaps call RARRAY(rb_array)->len when the correct 1.9 way 
is RARRAY_LEN(rb_array). I guess the old way is now completely removed 
in 1.9.1. We should update in all places to use the new way, as SWIG 
provides compatibility macros for ruby 1.8.

I''ve submitted a patch to SWIG to fix this. The patch is attached here;
it should be applied to /usr/local/share/swig-1.3.xx/ruby/file.i.

I''ll hope that the SWIG team pick this up soon and release it, so
won''t
hack a workaround into our

I''ve fixed all the occurrences in subversion. With the SWIG patch, SVN 
HEAD is now compiling ok with 1.9

Oops, SWIG-fix patch now actually attached.

This works great now.
