#
# This Makefile fragment implements handling for supported C/C++/Fortran
# compilers.
#
# The following variables may be set by the pkgsrc user in mk.conf:
#
# PKGSRC_COMPILER
# A list of values specifying the chain of compilers to be used by
# pkgsrc to build packages.
#
# Valid values are:
# ccc Compaq C Compilers (Tru64)
# ccache compiler cache (chainable)
# distcc distributed C/C++ (chainable)
# f2c Fortran 77 to C compiler (chainable)
# icc Intel C++ Compiler (Linux)
# ido SGI IRIS Development Option cc (IRIX 5)
# gcc GNU
# hp HP-UX C/aC++ compilers
# mipspro Silicon Graphics, Inc. MIPSpro (n32/n64)
# mipspro-ucode Silicon Graphics, Inc. MIPSpro (o32)
# pcc Portable C Compiler
# sunpro Sun Microsystems, Inc. WorkShip/Forte/Sun
# ONE Studio
# xlc IBM's XL C/C++ compiler suite (Darwin/MacOSX)
#
# The default is "gcc". You can use ccache and/or distcc with
# an appropriate PKGSRC_COMPILER setting, e.g. "ccache distcc
# gcc". You can also use "f2c" to overlay the lang/f2c package
# over the C compiler instead of using the system Fortran
# compiler. The chain should always end in a real compiler.
# This should only be set in /etc/mk.conf.
#
# USE_PKGSRC_GCC
# Force using the appropriate version of GCC from pkgsrc based on
# GCC_REQD instead of the native compiler.
#
# The following variables may be set by a package:
#
# 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_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, c99, 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/compiler.mk"
#
# .if !empty(CC_VERSION:Mgcc-3*)
# ...
# .endif
