I would like randomize the link order of my application from build to
build, and with link order I mean the sequence in which the object code
from the compiled project files are written to the application file.
Can I just rearrange the files in the project list, or does Xcode use
some more involved methods to determine how to build the binary ?
I've got a problem with piracy of my application and I want to mask
certain small changes to the program code with a large number of other
differences. If I make a change in a particular routine that checks
serial numbers, and release a build without any other changes it is
conceivable that the before and after application files can be compared
and the precise location of the serial number check is compromised.
So, while it is an odd request, I believe there is a sane reason. This
is part of a multi level approach to combatting piracy that by and
large has been successful. Back in the CW days I rearranged the build
order tab to achieve the same effect.
Thanks
Kent
