Hello,
when i run the bigdemo sample, the app crashes initially after opening
the “tip of the day” (it doesn’t when i don’t touch mouse and keyboard).
can’t even get to the main window. i ran it in gdb, it gives me the
following trace:

$ ruby -v
ruby 1.8.7 (2008-08-02 revision 0) [i686-linux]
don’t know if this is a bug, maybe its my own fault. i don’t really need
the bigdemo so it’s no problem for me, but maybe the wxruby devs are
interested.
i remember that it was working when i compiled ruby (same version)
without pthread support, maybe this is the prob (ruby 1.8.6 worked even
with pthread support). if you need further info, please tell me.
Greetings,
Niklas

Firstly, thank you for taking the time to report this in detail with a
backtrace. It’s much appreciated.
$ ruby -v
ruby 1.8.7 (2008-08-02 revision 0) [i686-linux]

No, it’s not your fault, and it’s not our fault either. With 1.8.7, the
ruby developers chose to change both the public APIs and aspects of the
GC/memory management internals. This broke any SWIG-generated ruby
libraries that use certain SWIG features (object tracking). IMO this was
a sloppy decision on a stable branch that reflects badly on ruby’s
development process, but - there we are.
Anyway, I recently committed a set of patches that I think fixed this
problem for Ruby 1.9, which has the same problem. If you’re willing to
test this out from wxRuby’s SVN with ruby 1.8.7 that would be very kind.
cheers

i did what you told me, compiled wxruby from svn, but it doesn’t seem to
work:
irb(main):001:0> require ‘wx’

i have no idea of what’s going wrong here, i’m not this experienced with
the internals of your code and with ruby development at all.

Thanks for trying it. You should be able to work around this error by
doing
rake WXRUBY_EXCLUDED=MediaCtrl,MediaEvent
Can I ask what wxWidgets you’re compiling against - eg a distro version,
or a self-built one?
thanks

this leaves me with exactly the same error:

The following wxWidgets features are not available and will be skipped:

$ wx-config --version-full
2.8.7.1
it’s a distro version (libwxbase2.8-dev on ubuntu). compiling wxruby
took long enough for me (about 30 minutes), so i didn’t try and compile
wxwidgets.

Fair enough. I haven’t tried using the distro packages on Linux myself,
but you might check that you also have libwxgtk-2.8 and libwxgtk2.8-dev
libwxbase contains only the non GUI classes. Only libwxgtk has
libgstreamer as a dependency, and that’s where the MediaCtrl code is
found.
Sorry for the inconvenience but wxwidgets has hundreds of compile-time
options and different ways to organise the library files. It’s quite
tricky to cope with all the variations.

Hello,
finally solved the problem as described here:
http://rubyforge.org/pipermail/wxruby-development/2008-May/001322.html
could have sworn that i didn’t get this result when i asked google about
the problem yesterday, but today i do 
maybe this should be fixed…
back to topic: it does now work, bug is gone.
Greetings,
Niklas
