# This is a set of make(1) rules to cross compile rescribe
# from Linux to other architectures - as we use Fyne, CGO
# is required, so we have to do more to cross compile than
# just rely on the standard go tools. It relies on osxcross
# being set up for the Mac builds, and mingw-w64 being
# installed for the Windows build.
#
# The standard go tools work perfectly for native builds on
# all architectures - note that "go generate" needs to be
# run before building to download the dependencies which are
# embedded.

# For osxcross, there are many versions of the MacOS SDK
# that are too old or too new to build Rescribe correctly.
# SDK 11.3, as extracted from XCode 12.5.1, seems to work
# perfectly for us.
OSXCROSSDIR=/opt/osxcross
# go < 1.25 needed for the MacOS SDK version we use due to
# https://go-review.googlesource.com/c/go/+/654376
# could probably use a newer SDK, but finding and building
# a working version is a pain
