Hi there, I am relative new to the wxRuby so please bear with me. I use Ubuntu Hardy Heron 8.04 release. I have installed the wxwidgets C libraries and then did a gem install wxruby The ruby extensions were downloaded and installed correctly. If i do $gem list --local .. wxruby (1.9.7) .. Then I tried to run a simple example "Hello World" as described in the tutorial http://wxruby.rubyforge.org/wiki/wiki.pl?Hello_World The frame is displayed correctly, but when i close the window i get: $ruby testwxruby.rb testwxruby.rb:10: [BUG] Segmentation fault ruby 1.8.6 (2007-09-24) [i486-linux] Aborted I tried to run another example mainly http://wxruby.rubyforge.org/wiki/wiki.pl?Using_Dialogs_To_Talk_To_Users Although the apps starts and works ok, when i close it i get the same message "Segmentation Fault" Is this a known issue? (The wxwidgets library installed in the system as seen by synaptic is 2.8.7.1-0-ubuntu3) and $ gem --version 1.1.1 (The rubygem was installed manually and not using the default that ubuntu comes which is 0.9.4-4) Thanks in advace, Christos -- Posted via http://www.ruby-forum.com/.
i forgot to mention the version of ruby $ruby --version ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux] This is the default that Ubuntu Hardy comes with.

I get this as well with every wxruby program I run. I wrote an email/topic about it a month or so back. I have a feeling it is to do with the ruby patchlevel 111. Right now I''mjust living with it and hoping it gets fixed. Woe is me. :( Lucas On Sun, 2008-05-25 at 12:07 +0200, Christos Vasilakis wrote:> i forgot to mention the version of ruby > > $ruby --version > ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux] > > This is the default that Ubuntu Hardy comes with. > > Christos > > Christos Vasilakis wrote: > > Hi there, > > > > I am relative new to the wxRuby so please bear with me. > > > > I use Ubuntu Hardy Heron 8.04 release.

I''ve just fixed a bug which could cause crashes on Linux (and possibly Windows) in 1.9.7 when Frames with MenuBars were closed. It could cause problems either on app exit or, if other frames remained open, when garbage collection ran. Hopefully this will address instabilities reported by several users - if anyone has the development set up on Linux and can test this with SVN head, it would be much appreciated. Sorry for the trouble alex
Hi Alex and thank you for your replay. All tests run on a clean ubuntu install with no previous wxruby instances(I had to reformat my hard drive some days ago) Here is what I did: I download the svn version of wxruby as described in the wiki: http://wxruby.rubyforge.org/wiki/wiki.pl?InstallingFromSource cvasilak at casper:~$ svn co svn://rubyforge.org/var/svn/wxruby/trunk/wxruby2 ... ... Checked out revision 1751. cvasilak at casper:~$ sudo rake ... cvasilak at casper:~$ sudo rake gem WXRUBY_VERSION=1.9.7 (just to make it work, I didn''t know what to supply as the wiki unfortunately doesn''t specify what, ignore the version tag for now) ... cvasilak at casper:~$ sudo gem install wxruby-1.9.7-x86-linux.gem <installed succesfully in /usr/lib/ruby/gems/1.8/gems/wxruby-1.9.7-x86-linux/> Tried to run the hello world found here: http://wxruby.rubyforge.org/wiki/wiki.pl?Hello_World cvasilak at casper:/home/cvasilak# ruby helloworld.rb helloworld.rb:4: [BUG] Segmentation fault ruby 1.8.6 (2007-09-24) [i486-linux] Aborted The window doesn''t even pop up I immediately get a segmentation fault. I tried to run the other example mainly http://wxruby.rubyforge.org/wiki/wiki.pl?Using_Dialogs_To_Talk_To_Users Although it runs fine when I close the window I get cvasilak at casper:/home/cvasilak# ruby okcancel.rb okcancel.rb:36: [BUG] Segmentation fault ruby 1.8.6 (2007-09-24) [i486-linux] Aborted I tried to run the minimal example found in the samples directory of the wxruby but I get the same segmentation fault when I exit. Some details: cvasilak at casper:/home/cvasilak# ruby -v ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux] cvasilak at casper:/home/cvasilak# gem -v 1.2.0 libwxbase2.8-0 2.8.7.1-0ubuntu-3 (default by repository) libwxgtk2.8-0 2.8.7.1-0ubuntu-3 (default by repository) Let me know of any tests you want me to run.

Hi Christos Thanks for trying this out.

I tried running the tests again on a very similar setup (Ubuntu 8.04, built against the 2.8.7 version wx packages) and both run fine for me and exit cleanly. I think what may be happening is that running with rubygems, you''re getting the original 1.9.7 with the bugs you first reported. cheers alex
Hi Alex, Using your recommentation I tried the following: First I have unistalled the wx-ruby gem root at casper:/home/cvasilak/wxruby/wxruby2# gem uninstall wxruby Successfully uninstalled wxruby-1.9.7-x86-linux <<Take notice that is a fake version number I have previously installed from the svn trunk, I just used the same version number of the release to keep the "rake gem" happy. This is not the official release and *no* previous instances of the wxruby is installed in the system.>> Then I tried to: root at casper:/home/cvasilak/wxruby/wxruby2# ruby /home/cvasilak/helloworld.rb /home/cvasilak/helloworld.rb:1:in `require'': no such file to load -- wx (LoadError) from /home/cvasilak/helloworld.rb:1 Which is OK since the wxruby library is not installed in the system. Then I tried to: root at casper:/home/cvasilak/wxruby/wxruby2# ruby -I lib/ /home/cvasilak/helloworld.rb /home/cvasilak/helloworld.rb:4: [BUG] Segmentation fault ruby 1.8.6 (2007-09-24) [i486-linux] Aborted I tried the second example but this time I get a window but upon exit I receive the segmentation fault. That''s really weird because as you say I use the same configuration as yours(Ubuntu 8.04, 2.8.7 wxwidgets etc). I don''t know if it helps but the only thing that I manually installed as far as ruby is concerned is the rubygem ver 1.2.0 because the rubygem package that comes with ubuntu is quite old(0.9.4) Here is a list of gems installed in the system root at casper:/home/cvasilak/wxruby/wxruby2# gem list --local *** LOCAL GEMS *** hoe (1.7.0) (dependencies) rake (0.8.1) (dependencies) ruby-pg (0.7.9.2008.01.28) (for postgresql access) rubyforge (1.0.0) (dependencies) RubyRRDtool (0.6.0) (for statistics using RRD technology) Let me know if you need more information. Christos PS Tomorrow is a public holiday here in Greece and I would be out of office and home (I will be in my father''s village with no net access) so If I don''t answer you immediately, bear with me, I would be back on Saturday. -- Posted via http://www.ruby-forum.com/.

But that really shouldn''t affect this. I''d suggest you try doing updating the sources to ensure you''re up to HEAD (svn up) then doing a clean rebuild (rake reswig; rake). Then try running it using the local library (ruby -Ilib ...) If you''re still getting the crash, it would be most useful to get a backtrace from gdb debugger. Try doing: gdb --args ruby -Ilib helloworld.rb Then at the gdb prompt: gdb> r < ENTER> If it stops after complaining about threads not found: gdb> c <ENTER> Then wait until it crashes. gdb should throw out some info. To get a full backtrace, do gdb> whe <ENTER> This should give a backtrace of where the crash occurred. thanks for your patience alex
Hi Alex, sorry for taking a bit longer to replay, other things kept me busy during the weekend and I didn''t have time to sit in the computer. Anyway, here is the list of things I did. I downloaded the svn version of wxwidgets root at casper:/home/cvasilak/wxruby-svn# svn co svn://rubyforge.org/var/svn/wxruby/trunk/wxruby2 .... Checked out revision 1758.

Unfortunately it seems that the debugging information has got truncated - I guess because you are using a release build of wxWidgets, and thus wxRuby tries to compile the smallest, fastest possible. If you were willing to try reproducing the error in a debug build, that should give more information. There is libwx package in Ubuntu with the -dbg suffix. If you install this, then run export WXRUBY_DEBUG=1 rake reswig rake and then try re-running the same process, we should get a more helpful backtrace. This is really puzzling as you have almost exactly the same setup as me, except that i built my own ruby. thanks alex
