# CROSS_COMPILE is a KBuild mechanism for specifying an external |
|
# toolchain with a single environment variable. |
|
# |
|
# It is a legacy mechanism that will in Zephyr translate to |
|
# specifying ZEPHYR_TOOLCHAIN_VARIANT to 'cross-compile' with the location |
|
# 'CROSS_COMPILE'. |
|
# |
|
# New users should set the env var 'ZEPHYR_TOOLCHAIN_VARIANT' to |
|
# 'cross-compile' and the 'CROSS_COMPILE' env var to the toolchain |
|
# prefix. This interface is consistent with the other non-"Zephyr SDK" |
|
# toolchains. |
|
# |
|
# It can be set from either the environment or from a CMake variable |
|
# of the same name. |
|
# |
|
# The env var has the lowest precedence. |
