# $NetBSD: bsd.compiler.mk,v 1.9 2004/02/05 21:26:16 jlam Exp $
|
|
#
|
|
# This Makefile fragment implements handling for supported C/C++/Fortran
|
|
# compilers.
|
|
#
|
|
# The following variables are used and should all be defined either
|
|
# in or before the first inclusion of bsd.prefs.mk:
|
|
#
|
|
# PKGSRC_COMPILER
|
|
# A list of values specifying the chain of compilers to be used by
|
|
# pkgsrc to build packages.
|
|
#
|
|
# Valid values are:
|
|
# distcc distributed C/C++ (chainable)
|
|
# ccache compiler cache (chainable)
|
|
# gcc GNU
|
|
# mipspro Silicon Graphics, Inc. MIPSpro
|
|
# sunpro Sun Microsystems, Inc. WorkShip/Forte/Sun
|
|
# ONE Studio
|
|
#
|
|
# The default is "gcc". You can use ccache and/or distcc with an
|
|
# appropriate PKGSRC_COMPILER setting, e.g. "ccache distcc gcc".
|
|
# The chain should always end in a real compiler. This should only
|
|
# be set in /etc/mk.conf.
|
|
#
|
|
# GCC_REQD
|
|
# A list of version numbers used to determine the minimum
|
|
# version of GCC required by a package. This value should only
|
|
# be appended to by a package Makefile.
|
|
#
|
|
# NOTE: Be conservative when setting GCC_REQD, as lang/gcc3 is
|
|
# known not to build on some platforms, e.g. 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_PKGSRC_GCC
|
|
# Force using the appropriate version of GCC from pkgsrc based on
|
|
# GCC_REQD instead of the native compiler.
|
|
#
|
|
# USE_GCC_SHLIB
|
|
# Indicates that a package uses GCC shared libraries, so we
|
|
# register a runtime dependency on the compiler package.
|
|
#
|
|
# USE_LANGUAGES
|
|
# Lists the languages used in the source code of the package,
|
|
# and is used to determine the correct compilers to install.
|
|
# Valid values are: c, c++, fortran, java, objc. The default
|
|
# is "c".
|
|
#
|
|
# The following variables are defined, and available for testing in
|
|
# package Makefiles:
|
|
#
|
|
# CC_VERSION
|
|
# The compiler and version being used, e.g.,
|
|
#
|
|
# .include "../../mk/bsd.prefs.mk"
|
|
#
|
|
# .if !empty(CC_VERSION:Mgcc-3*)
|

# ...

# USE_GCC2, USE_GCC3, USE_SUNPRO, USE_MIPSPRO
