I made the unfortunate mistake of moving from PB to xcode a few weeks
ago. I need to build a large project that includes C++ strings and run
it on 10.2. This all worked on PB on 10.2.8. Now I find that when I
build with xcode on 10.3 and run on 10.2.8, there are four unresolved
symbols ( btowc,iswctype,mbsrtowcs,towlower) when I try to launch.
These are all wchar routines that I believe are on 10.3 but not on
10.2. I don't think we are calling these directly, but suspect that
the C++ STL on 10.3 uses them. Has anyone built a project on 10.3 that
uses C++ strings and had it work on10.2? Does anyone have sources for
these routines that I might include in my project, or know where I can
find them in Darwin?
As I mentioned in the earlier message, if you want code to run on 10.2
and later, you need to use the 10.2.x SDK in your Project Settings.
The 10.3 headers use features of the 10.3 runtime that are incompatible
with older versions of Mac OS X.
