# For the building the driver for MacOS 10.11+, the preferred
# XCode version is 7.3.1.
#
# You can do this by downloading Xcode 7.3.1 as a dmg from Apple, then
# copying the contents into /Applications as Xcode-7.3.1.
# If you also want to build from "release_pre_10_11", you may want to
# also download "Xcode-4.3.3", and copy "MacOSX10.6.sdk" from it to
# SDK directory under:
# /Applications/Xcode-7.3.1.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/

-include localconfig.mk

# Can be set from the environment:
HORNDIS_XCODE ?= /Applications/Xcode*$(XCODE_VER).app

XCODE_VER ?= 7.3.1
XCODEBUILD ?= $(wildcard $(HORNDIS_XCODE)/Contents/Developer/usr/bin/xcodebuild)
