Code: [Select]
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11]

OBJ_DIR    = "obj"
SO_DIR     = "sfml"
DOC_DIR    = "doc"
EXT_DIR    = "ext"
INST_DIR   = "/opt/local/lib/ruby1.9/site_ruby/1.9.1/x86_64-darwin11/sfml" (found)

SFML_INC   = "include" (found)
SFML_LIB   = "lib" (found)

RUBY_INC   = "/opt/local/include/ruby-1.9.1" (found)
RUBY_LIB   = "/opt/local/lib" (found)
RUBY_LINK  = "-lruby.1.9.1"

CXX        = "/usr/bin/clang++"
CXXFLAGS   = "-pipe -O2 -Iinclude -Iext -I/opt/local/include/ruby-1.9.1 -I/opt/local/include/ruby-1.9.1/x86_64-darwin11 -Wall -Wextra "

LINK       = "/usr/bin/clang++ -dynamic -bundle"
LINK_FLAGS = "-Wl,-undefined,dynamic_lookup -Wl,-multiply_defined,suppress -Wl,-flat_namespace -L. -L/opt/local/lib  -arch x86_64 -L/usr/local/lib -Llib -L/opt/local/lib -lruby.1.9.1"

There are several options that I never used and some that look weird.
- Especially "-Wl,-undefined,dynamic_lookup" that tells the linker not to complain if there are undefined symbols, and look for them at runtime. This is weak linking, but I don't know why it's needed here.
- As for -multiply_defined, it's obsolete.
- -pipe is unknown to both Clang and ld. Only GCC knows it.
- And I don't know why -bundle is used. I'd rather expect -dynamiclib.


I changed the Rakefile with what you gave except some options (that do not exist with Apple's GCC) :
Code: [Select]
CXX = "g++"
CXXFLAGS = "-O3 -g -I#{SFML_INC} -I#{EXT_DIR} -I#{RUBY_INC} -I#{RUBY_INC}/#{CONFIG['arch']}"

LINK = "g++ -dynamiclib"
LINK_FLAGS = "-L. -L#{SFML_LIB} -L#{RUBY_LIB} #{RUBY_LINK}"

Which now gives
Code: [Select]
[ ceylo ceylo-pc ~/Desktop/rbSFML ] file /opt/local/lib/ruby1.9/site_ruby/1.9.1/x86_64-darwin11/sfml/graphics.so
/opt/local/lib/ruby1.9/site_ruby/1.9.1/x86_64-darwin11/sfml/graphics.so: Mach-O 64-bit dynamically linked shared library x86_64

instead of
Code: [Select]
[ ceylo ceylo-pc ~/Desktop/rbSFML ] file /opt/local/lib/ruby1.9/site_ruby/1.9.1/x86_64-darwin11/sfml/system.so
/opt/local/lib/ruby1.9/site_ruby/1.9.1/x86_64-darwin11/sfml/system.so: Mach-O 64-bit bundle x86_64

But I don't know a lot about Ruby or bundles so I don't know whether this change is useful.

Anyway, I still get the same error message when trying to launch Steel.

Actually I jsut realized. You are running on 64 bit and compiling for 64bit. What kind of version is your ruby installation? 32 or 64?

Oh wait never mind it says that right there. It is 64bit system. I am at a loss. Your SFML libraries are 64 as well? I don't know anything else.

The problem is more or less that Ruby can't read the library files for some reason. It can be all from architecture to the filesystem not letting it.

I'mma have a look at Ruby 'getting started' tutorials on OS X to see whether I missed something.

I'm wondering if there is some read-write settings you have to set for Ruby and Steel.rb and so on?

You could try moving around the sfml folder in the ruby folder until you get results XD
Like I said I am out of ideas of what the problem might be so I am just spewing out brute force things now.

Just realized, what happens if you create a ruby file in the ruby library directory and tries to load that? Can ruby find it?

Do you mean in /opt/local/lib/ruby1.9/site_ruby/1.9.1/x86_64-darwin11 ?
I copied all of the Steel files there and it still can't load.

I also tried to run ruby as root in case the issue would be related to permissions, but it's still failing.
Even if I replace the 'require' with 'require_relative' in Steel.rb.

Code: [Select]
Steel.rb:2:in `require_relative': cannot load such file -- /opt/local/lib/ruby1.9/site_ruby/1.9.1/x86_64-darwin11/sfml/graphics (LoadError)
from Steel.rb:2:in `<main>'

PS: I may have an idea...

Is the extension that the Ruby libraries should take in the $CONFIG variable ?

I don't know, I think so. It got like everything about the environment in there. Just launch up irb in a console and type:

require 'rbconfig'
rbConfig::CONFIG

DAMNIT, I keep pressing modify when I want to quote xD

Code: [Select]
irb(main):009:0> RbConfig::CONFIG['DLEXT']
=> "bundle"

According to http://guides.rubygems.org/c-extensions/ , this is what I was looking for.
And using this extension and reinstalling, here is what I get :
Code: [Select]
/opt/local/lib/ruby1.9/1.9.1/rubygems/custom_require.rb:36:in `require': wrong argument type false (expected Module) (TypeError)
from /opt/local/lib/ruby1.9/1.9.1/rubygems/custom_require.rb:36:in `require'
from Steel.rb:1:in `<main>'

Where line 1 is just
Code: [Select]
require "sfml/graphics"(I redownloaded the sources to make sure I hadn't introduced errors in the game's sources)

Alright just to be sure we get this right. I have to end the shared libraries on mac with bundle?

So more or less this should solve it for all platforms:
"#{SO_DIR}/#{file}.#{CONFIG['DLEXT']}"
I will create a "ceylo-branch" on the repo where I will do some printouts as of where it goes wrong and then you'll have to get back to me with the output log.

I will setup the branch now this weekend unless you know a better way to check. The error message doesn't say where it goes wrong it just says that something went wrong. What you could do until then is do a require on each library module and see what happens. This will give me a bit more precise information of what is happening.

rbSFML is just like SFML divided into system, window, graphics, audio. The difference is that rbSFML will check if the others have been loaded and if not load them for you.

boot up IRB in a console and type:
require 'sfml/system'
require 'sfml/window'
require 'sfml/graphics'

Can you try and find on what function it is that it crashes?

Yes sure!
It's the draw call at line ~262 (more or less, as I've added a few 'require') in Steel.rb.

Everything runs fine until I comment out this call.

Well that is a call to a method in the Game class. So you'll have to narrow done what in that function causes it. It begin at the line 67.

Uh, you're right. I didn't know how to recognize rbSFML methods from the Steel's ones.

So I've looked a bit further and I found out it crashes until I comment out "@app.view = @app.default_view" at line 59 of Steel.rb. I suppose it's related to rbSFML this time?
