# bsd.gcc.mk - Support for smarter USE_GCC usage.
#
# Created by: Edwin Groothuis <edwin@freebsd.org>
#
# For port developers:
# 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.
#
# As of 2010-06-06, USE_GCC=4.3 is deprecated and USE_GCC=4.3+ is
# transparently rewritten to USE_GCC=4.4+.
#
# Examples:
# USE_GCC= 4.2+ # port requires GCC 4.2 or later.
# USE_GCC= 4.5 # port requires GCC 4.5.
#
# 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 gfortran44 (lang/gcc44)
# USE_FORTRAN= g77 # use g77-34 (lang/gcc34; FreeBSD>=7)
# # or system f77 (/usr/bin/f77; FreeBSD<=6)
# 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.
