# bsd.gcc.mk - Support for smarter USE_GCC usage.
#
# Created by: Edwin Groothuis <edwin@freebsd.org>
#
# To request the use of a current version of GCC, specify USE_GCC=yes in
# your port/system configuration. This is the preferred use of USE_GCC.
# It uses the canonical version of GCC defined in bsd.default-versions.mk.
#
# USE_GCC=any is similar, except that it also accepts the old GCC 4.2-
# based system compiler in older versions of FreeBSD.
#
# If your port needs a specific (minimum) version of GCC, you can easily
# specify that with a USE_GCC= statement. Unless absolutely necessary
# do so by specifying USE_GCC=X.Y+ which requests at least GCC version
# X.Y. To request a specific version omit the trailing + sign.
#
# Examples:
# USE_GCC= yes # port requires a current version of GCC
# # as defined in bsd.default-versions.mk.
# USE_GCC= any # port requires GCC 4.2 or later.
# USE_GCC= 6+ # port requires GCC 6 or later.
# USE_GCC= 4.9 # port requires GCC 4.9.
#
# If you are wondering what your port exactly does, use "make test-gcc"
# to see some debugging.
