A package that uses +# pthreads may do one of the following: +# +# (1) Simply include pthread.buildlink2.mk. This will make the package +# use the native pthread library if it's available, or else the OPR +# package. The value of PTHREAD_TYPE may be checked to be either +# "native", or the name of the OPR package, or "none", e.g. +# +# # +# # package Makefile stuff... +# # +# .include "../../mk/pthread.buildlink2.mk" +# +# .if defined(PTHREAD_TYPE) && ${PTHREAD_TYPE} == "none" +# CONFIGURE_ARGS+= --without-pthreads +# .endif +# +# .include "../../mk/bsd.pkg.mk" +# +# Note that it's only safe to check and use the value of PTHREAD_TYPE +# after all other buildlink2.mk files have been included. +# +# (2) Add "native" to PTHREAD_OPTS prior to including +# pthread.buildlink2.mk.
