wxruby users - Sep 2008 - wxruby - compile trouble on 64bit linux (ubuntu)

hi, 
i''d like to give an report how i managed to get wxruby-1.9.8 installed
on ubuntu 8.04.
think this could be usefull for others.

after several errors during wxruby compilation i decided to get rid of
wxwidgets-libs and swig that came with / were installed via
ubuntu-packet-manager.
i got ahold of the mentioned versions of swig and wxwidgets and installed them
from source.

but this did NOT change the error (something with AboutDialog.o and unreferenced
Symbol).

what did the trick for me finally was to change
wxruby-1.9.8/rake/rakeconfigure.rb and add there some "-fPIC" to

--- snip --- 
# Flags to be passed to the C++ compiler
$cppflags = [ $wx_cppflags, $ruby_cppflags, 
              $extra_cppflags, $ruby_includes ,
"-fPIC"].join('' '')

# Flags to be passed to the linker
$ldflags  = [ $ruby_ldflags, $extra_ldflags, "-fPIC" ].join(''
'')

--- snap ---

did not find another solution to pass this arguments when invoking rake...

big thanks to the ppl working on development of wxruby.

regards

rene

Thanks for taking the time to write in about this. It''s mentioned on
the
wiki here:

http://wxruby.rubyforge.org/wiki/wiki.pl?HowToBuildWxWidgets

but I agree we should make that easier to find. I plan to write an 
INSTALL.txt to go with the source tar.gz which covers this sort of thing.

wxRuby gets its flags and options to pass to the C compiler from 
wxWidgets and Ruby, I think if wxWidgets is built with -fPIC, so will 
wxRuby, without having to change the rakefile.

Were you building against a static or dynamic wxWidgets?

thanks

Actually Alex,

wxRuby''s build process won''t receive from wx-config, or
ruby.h, I had to do
the same hack myself when I did the x86 build of wxRuby gem.  No matter what
I tried, I couldn''t get -fPIC in there, and I tried everything.

reproduceable - i recompiled wxwidgets explicitely with
''-fPIC'',
but compilation of wxruby failed nevertheless. - until the mentioned  
changes were made to rakeconfigure.rb

take care not to get sucked into /dev/null !

How can I get to the TextCtrl part of a SpinCtrl?  If I call disable on the
SpinCtrl it disables the arrows, but not the TextCtrl (under Windows XP).
How can I disable the TextCtrl part?

I''m not really sure - at the moment, I can''t seem to get the
TextCtrl to
accept input in a simple SpinCtrl. Do you have a sample programme you 
could show?

This question seems to have come up on the wxWidgets / wxPython list but 
I can''t find a definitive answer. You could try searching those further
by looking for wxSpinCtrl etc
