I am trying to figure out what the _REAL_SDKROOT build setting is about. For Xcode 3.2.6 it is defined in the environment if you execute a custom build rule as part of a target build in the IDE.
My experiments show that if you run the exact same target build from the command line, then _REAL_SDKROOT is not defined in the custom build rule environment.
I can't find any documentation for _REAL_SDKROOT, nor is it the name of a build setting within Xcode.
Does anyone know what it's for and how it should be set if I run a command line build? (For instance, I could probably examine SDKROOT and use it to derive a value for _REAL_SDKROOT if I had an algorithm.)
I realize that my custom build rule could ignore it entirely, but my real goal here is to have identical environments for the custom build rule script, whether the build is started from within the IDE or from the command line.
