I use a OS X framework in creating the FireRuby library on the Mac. All I
did to support this in the extconf.rb was add a line like the following into
this file...

$LDFLAGS = $LDFLAGS + " -framework Firebird"

I'm not sure if this is the way it's supposed to be done but it works for
me.

Framework?


I once built a game with Ruby/SDL [1] called Tadpoles [2].  (SDL is a  
powerful cross-platform Simple DirectMedia Library that's ideal for  
making fast graphics as in 2-D games). That was back in my Linux  
days.  When I moved back to Windows (temporarily) I found that Ruby/ 
SDL was far too difficult to install for me.  So I learned about RUDL  
[3] and found that it was much easier to install for Windows and  
actually featured some pretty nice Rubyesqueness.

With the rest of the geek world, I've since made the switch to Mac OS  
X (yeah, I know some of you are still holding back).  Now, I'd like  
to be able to write SDL-based apps for the Mac, but neither library  
seems ideal.

So, I'm attempting to make RUDL work on the Mac--but I need some help  
understanding how to make Ruby's extconf.rb / mkmf stuff work in  
conjunction with the Mac "Framework" style of distributing  
libraries.  Specifically, I've compiled SDL.framework which resides  
in /Library/Frameworks and need to the linker to know about that  
folder.  Unfortunately, when I run extconf.rb, it seems that the  
linker expects to find the libraries in the usual Unix style and in  
the usual Unix locations, using the "-lsdl" linker flag.

So, has anyone built an extconf.rb file that depends on a Mac OS  
Framework that I might investigate?  If not, how can I get extconf.rb  
to compile files like this, according to the SDL's Mac OS README:

"gcc -I/Library/Frameworks/SDL.framework/Headers MyProgram.c  
SDLmain.m -framework SDL -framework Cocoa"
