# This Makefile fragment is included by packages that use pthreads.
|
|
# This Makefile fragment is also included directly by bsd.prefs.mk.
|
|
#
|
|
# To use this Makefile fragment, simply:
|
|
#
|
|
# (1) Define USE_PTHREAD _before_ including bsd.prefs.mk in the package
|
|
# Makefile,
|
|
# (2) Optionally set PTHREAD_TYPE to force the use of a specific pthread
|
|
# implementation,
|
|
# (3) Include bsd.prefs.mk in the package Makefile,
|
|
# (4) And include this Makefile fragment in the package Makefile.
|
|
#
|
|
# The value of ${PTHREAD_TYPE} may be used after the inclusion of
|
|
# bsd.prefs.mk, which indirectly sets this value by including this file.
|
|
# E.g.,
|
|
#
|
|
# USE_PTHREAD= native
|
|
# .include "../../mk/bsd.prefs.mk"
|
|
#
|
|
# .if defined(PTHREAD_TYPE) && ${PTHREAD_TYPE} == "none"
|
|
# CONFIGURE_ARGS+= --without-pthreads
|
|
# .endif
