Package Makefiles may now directly include compiler.mk. * Don't include compiler.mk within bsd.prefs.mk any longer. It was only included for the purposes of defining CC_VERSION. Packages that want to test the value of CC_VERSION should now first include "../../mk/compiler.mk". Any GCC_REQD statements in package Makefiles should be set before compiler.mk is included. * Simpllfy pkgsrc/mk/compiler/*.mk files as a result of not needing to be included indirectly by bsd.prefs.mk. We remove the special handling associated with detecting whether the file was included from within bsd.prefs.mk. These files are now much more straightforward to write and understand. * G/C the BSD_PREFS_MK stack mechanism as the only users (compiler/*) no longer need it. * Ensure that directories are prepended to the PATH only from within bsd.pkg.mk.

#
|
|
# This Makefile fragment implements handling for supported C/C++/Fortran
|
|
# compilers.
|
|
#
|
|
# The following variables are used by this file:
|
|
#
|
|
# 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 (n32/n64)
|
|
# mipspro-ucode Silicon Graphics, Inc. MIPSpro (o32)
|
|
# 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

#
|

# .include "../../mk/bsd.prefs.mk"
