Is this information valid for C++ applications also? I am building an
app on 10.3, and want it to run on 10.2 and later (case #3 above). It
uses the C++ library extensively (STL, std::string, iostreams, etc).
Somehow I doubt that just changing the deployment target will make my
project compile & link against the correct version of the C++ headers
& libraries. That would imply (since the SDK is that of 10.3) that
they are binary-compatible between these two OS revs.
If you look inside the /Developer/SDK/ folders, it actually mirrors the
entire usr/include tree, including the gcc C and C++ headers and
libraries. Hopefully that should mean it will pick all of these up from
the SDK and not the root. Besides IIRC C++ on a Mac doesn't use dylibs,
it's 99% headers and 1% libstdc++.a which is a statically linked file
anyway, so even if you link against the 10.3 headers and static lib, it
should function fine on an older machine. (No, I haven't actually
tested this.)
What ever happened to backward binary compatibility -- I thought the
whole idea of different Versions of the same framework was to get away
from this SDK thing?
Cheers, Glen Low
