#!/usr/bin/env python
#
#   Builds a iPhone/iPad static library of PETSc
#
#   Before using removed /usr/include/mpi.h and /Developer/SDKs/MacOSX10.5.sdk/usr/include/mpi.h or
#      Xcode will use those instead of the MPIuni one we point to
#
#   export PETSC_ARCH=arch-ios

#   ./systems/Apple/iOS/bin/arch-ios.py [use --with-debugging=0 to get iPhone/iPad version, otherwise creates simulator version]
#      this sets up the appropriate configuration file
#
#   ./systems/Apple/iOS/bin/iosbuilder.py
#      this creates the PETSc iPhone/iPad library
#      this will open Xcode and give you directions to follow
#
#   open xcode/examples/examples.xcodeproj
#       Project -> Edit Project Setting  -> Configuration (make sure it is Release or Debug depending on if you used --with-debugging=0)
#       Build -> Build and Debug
