# 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 where still present.
|
|
#
|
|
# 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+ which requests at least GCC version X.
|
|
# 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= 9+ # port requires GCC 9 or later.
|
|
# USE_GCC= 8 # port requires GCC 8.
|
|
#
|
|
# If you are wondering what your port exactly does, use "make test-gcc"
|
|
# to see some debugging.
