Mac Forum / Programming / CodeWarrior / February 2004

We are aware of little differences like this in the header and
implementation.  We usually work with Apple to fix them in a short time
frame.  I don't specifically know of any 10.3 features which require
setting the MAC_OS_X_VERSION_MIN_REQUIRED and
MAC_OS_X_VERSION_MAX_ALLOWED flags but it may be necessary with ld and
not mwld.

May I ask what are you trying to get done,  that you think you will need
the MAC_OS_X_VERSION_MIN_REQUIRED and MAC_OS_X_VERSION_MAX_ALLOWED?  It
may be that we have a more direct way  or better way to make it work.  
Contact me in e-mail with what you need and I'll consult with
engineering.

AFAIK, no they aren't supported, at least not in 8.3 which is what I
use.  CodeWarrior does have an alternate means of specifying weak-linked
functions, though.  It involves adding to your project a text file with
an extension of ".wke", containing the symbols to weak-link against.
This file has the same syntax as a .exp file.  For example:

  # Drag Mgr functions added in MacOS X 10.3

  _NewDragWithPasteboard
  _GetDragPasteboard

BTW, the MAC_OS_X_VERSION_MIN_REQUIRED and MAC_OS_X_VERSION_MAX_ALLOWED
macros are used inconsistently in Apple's headers.  Some headers bracket
10.3-specific routines inside an #ifdef, in others the XXX_ATTRIBUTE
macros are used, and in others still there's no marking at all of
10.3-specific functions.

Hope this helps,

Paul
