I have an automated build process which compiles a iPhone app using a combination of xcodebuild and xcrun. When the build calls xcodebuild it passes in a xcconfig file which overrides certain settings.

IPHONEOS_DEPLOYMENT_TARGET = 4.3

ARCHS = armv7

VALID_ARCHS = armv7

LD_NO_PIE = NO

In theory this should ensure that the binary output from the build is a Position Independent Executable. Is there any way to examine the Binary to see if this is actually the case?

    With “otool -vh” you can see the “PIE” flag:

    $ otool -vh YourApp
YourApp:
Mach header
      magic cputype cpusubtype  caps    filetype ncmds sizeofcmds      flags
   MH_MAGIC     ARM         V7  0x00     EXECUTE    28       3532   NOUNDEFS DYLDLINK TWOLEVEL PIE
