[fxruby-users] Installing RubyFX on MacOS X 10.4.3

[Scott Willson]

Here's my experience with Tiger (Mac OS X 10.4.3) on a couple of  
PowerBooks. My skill with C begins and ends with "./configure; make;  
sudo make install" so ....

Fox 1.4.x compiles as-is from source from the command line if you  
have the Apple developer tools installed. The example programs work  
as they should -- if you remember to start your X server first.

On OS X 10.4.2, FXRuby (source or gem) wouldn't compile for me  
without the fixrbconfig gem. I am not sure if this is still necessary  
with 10.4.3, but I suspect so.

With the "fix," FXRuby compiles, but any attempt to use it dies with:
Module() error
Symbol not found in flat namespace
__ZN2FX10fxcheckJPGERNS_8FXStreamE

The DarwinPorts FXRuby port _does_ work, but it's at version 1.2. I  
made my own local port, changed all the "1.2"'s to "1.4"'s, and that  
worked, too.

So, what's different in DarwinPorts? Obviously, the link error points  
toward a missing JPEG library, and the only dependencies listed in  
the Portfile are libtiff, libpng, libjpeg, and libX11 for Fox. And  
"otool -L libFOX-1.4.0.dylib" shows the images libs as the only  
difference between working builds.

Long story short, I copied my DarwinPorts versions of libtiff,  
libpng, libjpeg
into /usr/lib on another PowerBook that does not have DarwinPorts nor  
Fink; recompiled Fox and FXRuby from source; and it worked.

I would bet that if OS X users download and compile the "Image  
Formats" libs on the Fox Download page first, we would be able to  
compile and run FXRuby, but I haven't put that to the test.

Hope that helps,
Scott
