# $NetBSD: cross.mk,v 1.10 2023/01/23 18:49:03 he Exp $
# These settings may be used to cross-build rust.
#
# They interact with the files/gcc-wrap script to pick the
# right compiler for the different phases of the build, and
# use the headers for the target when required. Note that the
# cross-root tree will need to have the required binary packages
# installed (curl etc., see list of buildlink3.mk includes in main
# Makefile).
# The gcc-wrap / c++-wrap script takes CROSS_ROOT environment variable
# to do a cross-build. The wrapper script assumes dest/ and tools/
# as a result of a cross-build of NetBSD as subdirectories of this root
