Hi,
We have customers using Tiger and others using Leopard (and snow leopard). There are some new enums available in later versions of the SDKs which are nice to have, and we can then build on leopard using them and distribute to Tiger where they are ignored and everyones happy. However, sometimes we need to debug on Tiger, and the code won't build, because the enum values (such as kHIWindowBitNoShadow) aren't defined.

A vague hint from apple suggested installing the 10.5 SDK from the xcode distribution, but the 10.5 xcode tools package refuses to open on 10.4, so I can't.

Can anyone tell me how to get to the point where I can build against leopard headers and debug on tiger?

Thanks
Andy
