# 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 defines a canonical, default version of GCC; the same version of
# GCC is also implied by USE_FORTRAN=yes.
#
# 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. Use of
# a Fortran compiler is declared by the USE_FORTRAN knob, not USE_GCC.
#
# Examples:
# USE_GCC= yes # port requires a current version of GCC
# # (4.6 as of today, subject to change).
# USE_GCC= 4.2+ # port requires GCC 4.2 or later.
# USE_GCC= 4.7 # port requires GCC 4.7.
#
# If your port needs a Fortran compiler, please specify that with the
# USE_FORTRAN= knob. Here is the list of options for that knob:
#
# USE_FORTRAN= yes # use gfortran46 (lang/gcc46)
# USE_FORTRAN= g77 # use g77-34 (lang/gcc34)
# USE_FORTRAN= ifort # use the Intel compiler (lang/ifc)
#
# Due to object file incompatiblity between Fortran compilers, we strongly
# recommend to use only one of them on any system.
#
# If you are wondering what your port exactly does, use "make test-gcc"
# to see some debugging.
