I don't understand what problem this is trying to solve. Can someone summarise? I can understand that some developers may not want to bring in Carbon dependency, but freetype already has a switch to turn off all the Carbon functions, is it not sufficient? But here are my thoughts anyway... - even with your changes, Carbon.h must still be included (for structure & type definitions, etc.) - although you don't call Carbon functions explicitly, the code is still Mac-only - the code is much less readable and much less maintainable. - the code uses private symbols (ex: ApplicationServicesVersionNumber) >I think it's sufficient as a draft for further discussion, >but attached ftmacdyn.h is NOT finished work, there are several >issues: > >* CPP feature: Current ftmacdyn.h uses C99 preprocessor macros > (to handle variadic arguments).

The legacy C compiler of Mac OS X 10.0 (using > precompiled header by default) cannot process it by default. _Nobody_ uses 10.0! 10.0 cannot play DVDs, 10.0 cannot burn CDs. It was essentially a beta OS. I strongly suggest that you target 10.2 as a minimum. At their summer 2007 WWDC conference, Apple stated that 67% of the 22 million active Mac OS X users are using 10.4, 23% are using 10.3, and 10% are using 10.2 or older. -- ____________________________________________________________ Sean McBride, B.
