[Plib-users] OS X Solution

[Mat D. <mdd...@en...>]

So I've made some headway on the OSX problem.

In order to get everything working correctly, I made a Carbon  
Framework, called plib, with all headers in it and compiled it with the  
libs in /usr/lib.  Then, I installed the framework in  
/System/Library/Frameworks/ and included it into my project.  I also  
removed all the headers from /usr/include/plib so that there wouldn't  
be any confusion.  For some reason, OSX was treating those headers as C  
headers and wasn't using C++.  You might post this solution to the site  
or something, it was a major hassle to get working.
