[wxruby-users] Segmentation Fault.

[Christos Vasilakis]

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.

Tried to run a program:
root at casper:/home/cvasilak/wxruby-svn# ruby /home/cvasilak/helloworld.rb
/usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in 
`gem_original_require': no such file to load -- wx (LoadError)
  from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:27:in 
`require'
  from /home/cvasilak/helloworld.rb:1

It's OK since the wx binding is not installed yet in the system.

Tried to launch with the -I lib argument

root at casper:/home/cvasilak/wxruby-svn/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 get the segmentation fault. Then I tried running it with gdb as you 
suggested:

gdb --args ruby -I lib /home/cvasilak/helloworld.rb
....
....
Program received signal SIGSEGV, Segmentation fault.

I tried the other example that popups a window first and then segfaults 
upon exit but I get the same error in gdb

gdb --args ruby -I lib /home/cvasilak/okcancel.rb
...
...
Program received signal SIGSEGV, Segmentation fault.
