# As different environments have different versions of nightly installed, but
|
|
# rustup / cargo does not take "the latest installed nightly" for a toolchain,
|
|
# a good value is determined dynamically. Typical values this takes are
|
|
# `nightly` (on regular installations) and `nightly-2022-03-08` (or whichever
|
|
# date it is currently pinned to) in riotbuild.

|
|
# the default value will likely not be usable but at least set the user on the
|
|
# right track.

# BINDIR, for that would allow different boards using the same CPU to share

# compiled code (unless they they build conditionally on environment variables,
|
|
# like riot-sys does). This is not done for two reasons:
|
|
#
|
|
# * Overriding BINDIR (like is done in Murdock) would not take effect,
|
|
# requiring additional overrides to enable out-of-tree building.
|
|
#
|
|
# * Switching back and forth between two boards of the same CPU requires
|
|
# riot-sys rebuilds. (On its own, this would be outweighed by the shared
|
|
# compilation of other modules).
