I'm starting to like your compiler.. It's finding errors I've missed ^^

Alright let's try it out now.

Do you know that Clang isn't specific to Mac OS X ? You can give it a try quite easily on Linux. Dunno what about Windows.

Alright another try.

And I can't really right now because I am sitting at my workstation doing the changes over the Github web editor.

[Laurent]

Dunno what about Windows

Last time I tried (3.0.0), there were bugs that prevented it to work. And you have to build it yourself, there's no precompiled package.

Yeah it's still under heavy development at the moment : http://clang.llvm.org/cxx_status.html
But I really love how clear the error messages are, compared to GCC.

[Groogy]

Finally compiled
I am now Clang++ proof 

Let me know how writing actual ruby code goes. I hope it works out well
And most important, have fun coding. I think that's the most important aspect of Ruby. It makes coding really fun, fast and simple. And let me know if you feel that I disrupt and of the Ruby principles(if you know them).

[Ceylo]

I don't want to disappoint you but... my purpose was just to test someone else's game, not learn Ruby . At least, for now .


Edit: I tried this, without success

Can't rake test and rake samples be a bit more verbose about why sfml/system couldn't be loaded ?

[Groogy]

WAAARGHH!!!! *breaths heavily*
Let me guess, You are going to play Steel?

The test is not valid, just take my example script from a few pages back and test. Does that work then the game you are going to test will work.

[Ceylo]

WAAARGHH!!!! *breaths heavily*

Yup I want to give it a try .

PS: I edited the above message.

[Groogy]

Test and samples are out of date so don't trust them. I should just have them removed really as it confuses people. Take the test script from a couple of pages back on this thread and if that one runs the game runs

[Ceylo]

Well, the point is I'm getting the same error when I try to run Steel :

Code: [Select]

[ ceylo ceylo-pc ~/Downloads/Steel src ] ruby Steel.rb
/opt/local/lib/ruby1.9/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- sfml/graphics (LoadError)
from /opt/local/lib/ruby1.9/1.9.1/rubygems/custom_require.rb:36:in `require'
from Steel.rb:1:in `<main>'
That's why I'd like to understand why it's failing.

Thanks,
Ceylo

[Groogy]

That's tricky.. as far as I can see the library is installed to the correct folder. Try adding this to the top of the main ruby file in Steel:

$: << "/opt/local/lib/ruby1.9/site_ruby/1.9.1/x86_64-darwin11"

[Ceylo]

It didn't change anything.

[Groogy]

Hmm maybe there is a missing flag to the linker to create the shared library so it becomes invalid somehow? Do the compilation again with rake verbose and give it to me. Also say if you see some weird value in the CXX and LINK values since I don't know what's right in Clang.

If this fails just swap to GCC by giving these values to these variables:

CXX = "g++"
CXXFLAGS = "-O3 -g -I#{SFML_INC} -I#{EXT_DIR} -I#{RUBY_INC} -I#{RUBY_INC}/#{CONFIG['arch']}"

LINK = "g++ -shared"
LINK_FLAGS = "-Wl,--enable-auto-image-base,--enable-auto-import -L. -L#{SFML_LIB} -L#{RUBY_LIB} #{RUBY_LINK}"

Edit: Actually just tried including a file that doesn't exist. That is the exact message you get. So somehow Steel is not able to read from that path. So installation was correct now I don't know really since this feels like Mac-space. Not 100% sure.
