# This Makefile fragment implements handling for supported
|
|
# C/C++/fortran compilers.
|
|
#
|
|
# This file should NOT be included from pkg Makefiles, as it is
|
|
# automatically included by bsd.pkg.mk.
|
|
#
|
|
# The following variables are used:
|
|
#
|
|
# GCC_REQD
|
|
# Sets the minimum required version of gcc. Packages can set
|
|
# this if they are known to require gcc>2.8.0, which is the
|
|
# compiler shipped with NetBSD 1.5.
|
|
#
|
|
# Note: Be conservative when setting GCC_REQD, as lang/gcc3 is
|
|
# known not to build on some platforms, eg. Darwin. If gcc3 is
|
|
# required, set GCC_REQD=3.0 so that we do not try to pull in
|
|
# lang/gcc3 unnecessarily and have it fail.
|
|
#
|
|
# USE_GCC_SHLIB
|
|
# Indicates that a package uses GCC shared libraries, so we
|
|
# register a runtime dependency on the compiler package.
|
|
#
|
|
# USE_GCC2
|
|
# Use pkgsrc gcc2 from lang/gcc. This overrides any GCC_REQD
|
|
# setting.
|
|
#
|
|
# USE_GCC3
|
|
# Use pkgsrc gcc3 from lang/gcc3. This overrides any GCC_REQD
|
|
# setting.
|
|
#
|
|
# USE_PKGSRC_GCC
|
|
# Use the appropriate version of GCC from pkgsrc based on
|
|
# GCC_REQD.
|
|
#
|
|
# USE_SUNPRO
|
|
# Use the Sun Microsystems Inc. WorkShop/Forte/Sun ONE Studio
|
|
# compiler collection.
|

|
# USE_MIPSPRO

# Use the Silicon Graphics, Inc. MIPSpro compiler.
