# $NetBSD: compiler.mk,v 1.111 2024/01/27 00:03:49 wiz Exp $
#
# 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)
# clang Clang C and Objective-C compiler
# 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.
#
# COMPILER_USE_SYMLINKS
# If set to yes, use symlinks for the compiler drivers, otherwise
# shell scripts are created. The default is yes.
#
# CHECK_COMPILER
# If set to yes, fail early if the compiler.mk variables are not
# set correctly.
#
# ALLOW_NEWER_COMPILER
# If set to no, fail early if a package requires newer compiler
# features than supported by the system's compiler. If set to
# yes (the default), pkgsrc may attempt to build a newer compiler
# to use instead.
#
# The following variables may be set by a package:
#
# USE_LANGUAGES
# Declares the languages that should be made available
# via pkgsrc's compiler wrappers.
#
# Valid values are: c, c++, fortran, fortran77, java, objc,
# obj-c++, ada.
#
# There is deprecated support for expressing a specific language
# dialect (e.g. c++17) in USE_LANGUAGES. This both requires a
# compiler that supports that dialect, and adds -std= flags via
# the wrappers. (Instead, following the documentation below,
# the language dialect should be added to USE_C_FEATURES or
# USE_CXX_FEATURES to require a compiler with support, and if
# the package does not add -std flags itself, then FORCE_C_STD
# or FORCE_CXX_STD should be set.)
#
# Deprecated values are: c99, gnu99, c11, gnu11, c17, gnu17,
# c++03, gnu++03, c++0x, gnu++0x, c++11, gnu++11, c++14,
# gnu++14, c++17, gnu++17, c++20, gnu++20, c++23, gnu++23.
#
# The default is "c".
#
# USE_CC_FEATURES
#
# Declares the C compiler features required by the package.
#
# This is used to (optionally) install a newer compiler
# than provided by the system, or to skip building the package.
#
# Valid values are: c99, c11, c17, has_include.
#
# USE_CXX_FEATURES
#
# Declares the C++ compiler features required by the package.
#
# This is used to (optionally) install a newer compiler
# than provided by the system, to or skip building the package.
#
# Valid values are: c++11, c++14, c++17, c++20, c++23, has_include,
# regex, filesystem, unique_ptr, charconv, parallelism_ts,
# put_time, is_trivially_copy_constructible.
#
# FORCE_C_STD
#
# Overrides the compiler's default C dialect to ensure that a
# specific language variant is used. This is useful if a package
# uses features from a later or earlier C standard but doesn't set
# -std=cXX, since the default dialect choice of different compiler
# versions is not consistent. It is also useful if a package
# wants to use GNU language extensions without setting -std=gnuXX.
#
# Valid values are: c90, c99, c11, gnu90, gnu99, gnu11
#
# FORCE_CXX_STD
#
# Overrides the compiler's default C++ dialect to ensure that a
# specific language variant is used. This is useful if a package
# uses features from a later or earlier C++ standard but doesn't set
# -std=c++XX, since the default dialect choice of different compiler
# versions is not consistent. It is also useful if a package
# uses GNU language extensions without setting -std=gnu++XX.
#
# Valid values are: c++03, c++11, c++14, c++17, c++20, c++23,
# gnu++03, gnu++11, gnu++17, gnu++20, gnu++23
#

# package Makefiles:
