Subject: [fxruby-users] Error Running Hello, World program
Message-ID: <AANLkTikqTT6CjHstVcatUMKf8GGzS4=UKcJsmLaX_N8R@mail.gmail.com>

Hello,

I followed the steps here:

https://github.com/lylejohnson/fxruby/wiki/Setting-Up-a-Linux-Build-Environment

Created a hello.rb program as described here:

http://www.fxruby.org/doc/tutorial1.html

When I run hello.rb:

ruby hello.rb

I get the following error:

<internal:lib/rubygems/custom_require>:33:in `require':
/usr/local/lib/ruby/gems/1.9.1/gems/fxruby-1.6.20-x86-linux/lib/fox16.so:
undefined symbol: rb_thread_pending -
/usr/local/lib/ruby/gems/1.9.1/gems/fxruby-1.6.20-x86-linux/lib/fox16.so
(LoadError)
 from <internal:lib/rubygems/custom_require>:33:in `rescue in require'
 from <internal:lib/rubygems/custom_require>:29:in `require'
 from
/usr/local/lib/ruby/gems/1.9.1/gems/fxruby-1.6.20-x86-linux/lib/fox16.rb:6:in
`<top (required)>'
 from <internal:lib/rubygems/custom_require>:33:in `require'
 from <internal:lib/rubygems/custom_require>:33:in `rescue in require'
 from <internal:lib/rubygems/custom_require>:29:in `require'
 from hello.rb:1:in `<main>'


Not quite sure what I'm doing wrong here, but suspect it's something with
the fxruby gem because here's what I get in irb:

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require_gem 'fxruby'

NoMethodError: undefined method `require_gem' for main:Object
from (irb):3
 from /usr/local/bin/irb:12:in `<main>'

irb(main):003:0> include Fox
NameError: uninitialized constant Object::Fox
 from (irb):4
from /usr/local/bin/irb:12:in `<main>'

Thanks for your help!

Ilya

in irb just try

require 'fox16'

include Fox

and if you get trues then try

application = FXApp.new("Hello", "FoxTest")
main = FXMainWindow.new(application, "Hello", nil, nil, DECOR_ALL)
FXButton.new(main, "&Hello, World!", nil, application, FXApp::ID_QUIT)
application.create()
main.show(PLACEMENT_SCREEN)
application.run()

Subject: [fxruby-users] Installation on OpenBSD systems
Message-ID: <op.vqcdxxyqev5o3h@kes.fritz.box>

Hello,

I would like to transform some Ruby/TK-programs to FXRuby. I took the Ruby
and FOX16 binaries of my OpenBSD4.8 system and installed the FXRuby-1.6.19
source code. Unfortunatly it does not work. The fault messages look similar
to the discription on the build document but adding -lgcc to the
LIBS line in the makefile does not fix the problem.

I am happy if someone could drop a hint.
Alwin
