Xcode app version not compatible with Mac OS X version

Question

am using Os X 10.6.4 and X code Version 3.2.3 for developing some simple app files and using PackageMaker to distribute these app files. But when trying to run the package on some other mac I am getting error that the package is not compatible with the Os X its running and file would not be installed. Is this a problem with X code or package maker. sorry for reposting it but although I tried changing base SDK to 10.5, it was getting compiled and ran well on mac I am using for development (Mac OS X 10.6.4) but when installed on mac running OS X 10.5 the .app files were grayed out and message poped up saying 'you cannot use this version of application with this version of Mac'. Any idea why is this happening? Also as mentioned earlier I am using IBOutlet for accepting user date from form and then writing that into a text file. Any idea or solution about it?

Answer 1

Do you have anything set in your Info.plist for the LSMinimumSystemVersion key? This is one place the system looks.

Answer 2

When I was brand new I had trouble figuring this out... Make sure that your Base SDK and deployment target are 10.5 and that you have the right compiler on(GCG4.0/4.2), also make sure that when you change these settings you change it for both Release and Debug, I once made this mistake of changing it only on debug, and when I built for release it only worked on 10.6 because I didn't change those settings.
