First, try setting this in your application's *.pro file:

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.6

This should hopefully enable weak linking for your build, which in theory would allow it to run on 10.6.

If that doesn't work, you have two other options. Build on 10.6. The binaries will run on 10.7 and 10.8. Or, manually try to install the 10.6 SDK as described here:

Where to get macos SDK 10.6 for Xcode?

You will then have to configure your Qt project to target that SDK:

QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.6
QMAKE_MAC_SDK = /Developer/SDKs/MacOSX10.6.sdk

@SharanabasuAngadi Also make sure that your app bundle contains Qt libraries – Kamil Klimek Oct 31 '12 at 11:06

That's not true; you can build against the 10.8 SDK and still target 10.6! You just need to ensure you don't use (or provide alternatives to) any API that doesn't exist under 10.6 (including auto-layout in NIBs). – trojanfoe Oct 31 '12 at 11:27
Thanks for comment trojanfoe, can you please tell me bit clearly – Sharanabasu Angadi Oct 31 '12 at 11:31
@SharanabasuAngadi You don't need the 10.6 SDK at all and you can use the latest SDK supplied with the latest Xcode. This is complicated however by the use of Qt, which will also need to be built to support 10.6 (and this is probably where the error lies). – trojanfoe Oct 31 '12 at 11:35
@ trojanfoe: ok, But I have the issue in running the app on 10.6, Can you suggest me how can I fix it – Sharanabasu Angadi Oct 31 '12 at 11:45
@SharanabasuAngadi You need to provide more information. Press the "Report..." button so we can see where it crashed. – trojanfoe Oct 31 '12 at 11:53
@SharanabasuAngadi I think trojanfoe might be right. What happens if you simply set `QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.6` in the *.pro file of your application? – Nikos C. Oct 31 '12 at 12:08
@trojanfoe I updated my answer. You're right. Apple's docs say that weak linking is there exactly for this purpose. – Nikos C. Oct 31 '12 at 12:11
@Nikos Chantziaras, ok will check that – Sharanabasu Angadi Oct 31 '12 at 12:12
@Nikos Chantziaras, Still no use Same issue – Sharanabasu Angadi Oct 31 '12 at 12:34
