# 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.
|
|
#
|
|
# This should be disabled only for debugging.
|
|
#
|
|
# COMPILER_USE_SYMLINKS
|
|
# If set to yes, use symlinks for the compiler drivers, otherwise
|
|
# shell scripts are created. The default is yes.
|
|
#
|
|
# 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"
