# 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
