Hi,

I am compiling Maya Ruby plugin on OS X and during the linker stage,  
the linker is unable to find rb\_gc\_enable() and similar functions.

It is able to find the other Ruby function so I think the libraries  
are fine.

I have compiled the code on WindowsXP and it was fine.

I only have difficulty on OS X.

As the libraries naming is different on the two platforms, I don’t  
have a one-to-one comparison.

There is a libruby.dylib file [shipped standard with OSX] and it is  
providing all the other function except those associated with GC.

Anyone familiar with linking with Ruby libraries on OS X?

Specification:  
OS X 10.4.4  
Ruby 1.8.2

I am building under XCode 2.1 and have customise it to use GCC 3.3  
(Alias Maya requires gcc 3.3 for the plugins to work with their  
applications)

I also need to deploy it as a 10.3.9 runtime package for Alias Maya  
to work.

Cheers
