GCC 10 releases, switch to that over lang/gcc10-devel when GCC 10 is requested. Use lang/gcc11-devel when GCC 11 is requested, but note that this is absolutely experimental and subject to constant change and likely breakage over the next half year at least before that release series enters stabilization. Use at your own risk.

# 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.
