Problems to build app for 10.5 with xcode 3.2.3

I was trying to compile my project under xcode 3.2.3 to make it run on OS X 10.5 I've set the SDKROOT to macosx10.5 and Deployment Target to开发者_开发知识库 10.5, but it still shows to use SDK 10.6 during compiling. And it changed the minimumversion to 10.6 in built Info.plist.

Anybody get any ideas on this??

Check that your SDK setting etc is not being overridden, i.e. look at the target settings. Also make sure that you didn't change it just for, say, Development or Deployment builds - you probably want it set to the same for both.

Yes Paul, I set all to 10.5 for both Development and Deployment builds. But it still uses sdk 10.6 during compiling.
