#
# Helper to set build tool & SDK versions for iOS configurations
#
# This file sets up the following configuration variables:
#
#   QMAKE_IOS_XCODE_VERSION          - version number of Xcode being used
#   QMAKE_IOS_SDK_VERSION            - version number of iOS SDK
#
# Used in:
#
#   mkspecs/common/ios/clang.conf
#   mkspecs/common/ios/qmake.conf
#   mkspecs/unsupported/macx-iosdevice-clang/qmake.conf
#

#
# IMPORTANT:
#
# Xcode versions >= 4.10 & < 5.0 and versions >= 10.0 are not supported due to
# the way the version checks are done here. As Apple (so far) has not used
# minor version numbers greater than 3 for Xcode, and the Xcode major version
# has only changed three times in the period 2003-2012, this is viewed as an
# acceptable limitation.
#

# Edit values below to match iOS build environment, or leave blank for
# autodetection (slower!)

# Xcode version used

# iOS SDK version used
QMAKE_IOS_SDK_VERSION   =

# Do not edit values below here if using a pre-built SDK
