# $NetBSD: pthread.buildlink3.mk,v 1.29 2010/02/06 11:06:19 obache Exp $
#
# The pthreads strategy for pkgsrc is to "bless" a particular pthread
# package as the Official Pthread Replacement (OPR). The following
# variables may be set before including this file:
#
# PTHREAD_OPTS?= # empty
# A list of options to configure the search for a suitable pthreads
# implementation.
#
# "native" means that only a native pthreads implementation is
# acceptable.
#
# "optional" will override the effects of any instance of
# "require". This should _only_ be used by those packages
# that can be built with or without pthreads independently
# of whether any of its dependencies need pthreads.
# Currently, this is only www/mozilla, which uses its own
# threading library if native pthreads are unavailable,
# despite that it uses GTK+, which _does_ need pthreads.
#
# "require" means that the package is skipped silently when no
# implementation can be found.
#
# By default, the native pthreads implementation is used if it's
# available. Otherwise the OPR is used.
#
# PTHREAD_AUTO_VARS?= no
# This variable specifies whether the values of the variables
# PTHREAD_{CFLAGS,CPPFLAGS,LDFLAGS,LIBS} should be automatically
# added to their respective variables.
#
# After inclusion of this file, the following variables may be examined:
#
# PTHREAD_TYPE
# The type of pthreads implementation that has been found.
#
# "native" means that the native pthreads implementation is used.
#
# "none" means that no suitable pthreads implementation could be
# found.
#
# Any other value is the name of the package that is used as the
# pthread implementation.
#
# Note that it's only safe to check and use the value of PTHREAD_TYPE
# after all other buildlink3.mk files have been included.
#
# The case where a package must use either the native pthread library or
# some pthread package aside from the OPR (e.g. "ptl2") can be solved as
# follows:
#
# PTHREAD_OPTS+= native
# #
# # more package Makefile stuff...
# #
# .include "../../mk/pthread.buildlink3.mk"
#
# .if defined(PTHREAD_TYPE) && ${PTHREAD_TYPE} == "none"
# . include "../../devel/ptl2/buildlink3.mk"
