Re: [Plib-users] can't link on OS X

[Kevin W. <wa...@co...>]

Okay, I have looked around on the internet and it seems to be more of  
a gcc problem than a Mac OS X problem. For some reason, the compiler  
is trying to process the file (ul.h) as an extern "C" file rather  
than a c++ file. I can't seem to make XCode stop doing this.
