Hello,

I am new to ruby and rubygame and have tried to get  
[http://rubygame.org/wiki/Generic\_Game\_Template](http://rubygame.org/wiki/Generic_Game_Template) to work as a starting  
point, but I only get this error:

/usr/lib64/ruby/gems/1.8/gems/rubygame-2.5.3/lib/…/ext/rubygame/rubygame\_core.so:

/usr/lib64/ruby/gems/1.8/gems/rubygame-2.5.3/lib/…/ext/rubygame/rubygame\_core.so:

undefined symbol: SDL\_FreeSurface -  
/usr/lib64/ruby/gems/1.8/gems/rubygame-2.5.3/lib/…/ext/rubygame/rubygame\_core.so

(LoadError)  
from /usr/lib64/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:31:in  
`require' from /usr/lib64/ruby/gems/1.8/gems/rubygame-2.5.3/lib/rubygame.rb:34 from /usr/lib64/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem\_original\_require’  
from /usr/lib64/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:36:in  
`require’  
from main.rb:2

I have all dependencies for rubygame installed.  
I use Gentoo Linux with a 32/64bit multilib profile. SDL, ruby and  
rubygame are compiled as 64bit app.

I hope somebody can help me.

Greetings

Sebastian Beßler

Hello,

this mail is just for reference, for people facing the same problem as  
me.

I have solved this problem by rebuilding rubygame without -as-needed in  
my LDFLAGS.
