For USE_LANGUAGES there is already a pkglint warning, but for GCC_REQD it is missing. It's better to have this check directly in the infrastructure since it is more reliable. This check is disabled by default, to not cause any new breakage. It should be enabled in bulk builds.

#
|
|
# 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.
|
|
#
|
|
# The following variables may be set by a package:
|
|
#
|
|
# USE_LANGUAGES
|
|
# Declares the languages used in the source code of the package.
|
|
# This is used to determine the correct compilers to make
|
|
# visible to the build environment, installing them if
|
|
# necessary. Flags such as -std=c++99 are also added.
|
|
# Valid values are: c, c99, c++, c++03, gnu++03, c++0x, gnu++0x,
|
|
# c++11, gnu++11, c++14, gnu++14, c++17, gnu++17, fortran,
|
|
# fortran77, java, objc, obj-c++, and ada. The default is "c".
|
|
#
|
|
# The above is partly aspirational. As an example c++11 does
|
|
# not force a new enough version of gcc.
|
|
#
|
|
# 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"
