cross development

Hi,

I'm interested to know what people think of the value of cross development (for earlier Mac OS's).

Under Panther I had always built my audio units against the 10.2.8 SDK. However I've just got Tiger/XCode2.1/the latest AU SDK etc. and now I'm having problems building against either 10.3.9 or 10.2.8, in both cases because the AU SDK is using new features of the OS.

So I guess the answer might be to retrieve and use an older AU SDK.

It's all getting to be a bit of a bother though. So my question is - is it worth it? Has anyone ever heard from a user that their plug-in doesn't run on an older OS than the one it was developed for?

As a more general point, I'd like to hear what the Apple guys' policy is as regards developing the AU SDK in such a way that it can be used with older OS's.

For the record these are the problems I've found so far:

When building for 10.3.9, I get
- "MusicDeviceMIDIEventProc undeclared" which seems to be due to a change in AudioUnit/MusicDevice.h.
- "kAudioFormatAppleLossless undeclared" and similar for kAppleLosslessFormatFlag_16BitSourceData etc.


When building for 10.2.8, I get
- "kControlStaticTextIsMultilineTag undeclared" from the carbonview part of the SDK
- plus the same errors as for 10.3.9.



cheers, os.
