Application build on Xcode 2.4 with mac 10.5 sdk is not getting invoked in Mac 10.3.9?

I have build an application with xcode 2.4 (universal binary with sdk10.5) on Mac 10.6, when im invoking the application in mac 1开发者_JS百科0.3.9 the application is not getting invoked. Its workin in 10.4 and above version?

Can someone suggest me on this..

The Mac OS X 10.5 SDK targets the Mac OS X system version 10.5. It's no surprise it's not working with earlier versions.

Use the Mac OS X 10.3 SDK if you want your program to run on Panther. I believe it is still available as an optional package when you install Xcode.

Hey i loaded the libraries dynamically which i was using and getting the function pointers of the required function, now the build is working fine in 10.3.9??? i need not change the sdk's to make the application run in 10.3.9..

i used dlopen('); and dlsym().

Thanks You.
