# 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 version of GCC, you can easily specify
# that with the "USE_GCC=" statement. If you need a certain minimal version,
# but don't care if about the upperversion, just the + sign behind
# the version. Note that the Fortran compiler is specified with the
# USE_FORTRAN knob.
#
# For example:
# USE_GCC= 4.2+ # port requires GCC 4.2 or later to build with.
# USE_GCC= 4.3 # port requires GCC 4.3 to build with.
#
# 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 gfortran43 (/lang/gcc43)
# 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.
