#-*- tab-width: 4; -*- # ex:ts=4 # # bsd.gcc.mk - Support for smarter USE_GCC usage. # # Created by: Edwin Groothuis # # 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+ 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= 7+ # port requires GCC 7 or later. # USE_GCC= 5 # port requires GCC 5. # # If you are wondering what your port exactly does, use "make test-gcc" # to see some debugging. # # $FreeBSD$ GCC_Include_MAINTAINER= gerald@FreeBSD.org # All GCC versions supported by the ports framework. Keep them in # ascending order and in sync with the table below. # When adding a version, please keep the comment in # Mk/bsd.default-versions.mk in sync.
