While building after creating the Development Scheme for Mac OS X Lion 10.7, the above build errors are generated. Any clues how I can compile OsiriX on Mac OS X Lion 10.7?

    Although this answer doesn’t seem conclusive, I would like to mention what worked and what didn’t. Before that, I am using Xcode version 4.3.2 and Mac OS X Lion 10.7.4. I downloaded the source code zip file for OsiriX.

    1. Select “Unzip Binaries” and My Mac 32-bit as the target scheme first, and build and run. (This one was always successful).

    2. Select “Osirix” and My Mac 32-bit as the next target scheme and, in this version of Xcode it says “Validate Project Settings”, as it seemed to be necessary to update the compiler from llvmgcc42 to Apple LLVM, and change the Base SDK to latest Mac OS X (10.7) from the current 10.6 version.

    When this change was performed, it threw up varieties of build errors, like the one on my original question, and Apple Mach-O linker error, CLang error, exited with code 1. and so on.

    The successful compilation of Osirix in my opinion depends on keeping the old compiler and not updating to latest project settings.
