# $NetBSD: dlopen.buildlink3.mk,v 1.18 2015/10/10 13:13:45 jperkin Exp $
dlopen.buildlink3.mk should be added to packages that use dlopen() to load shared objects. Some platforms require pthreads to be linked into the application if it uses dlopen() or else the applications will core dump when they dlopen a shared module that _is_ linked with pthread support. Including dlopen.buildlink3.mk in a package Makefile will cause pthread.buildlink3.mk to also be included. It is up to the package to ensure that PTHREAD_{CFLAGS,LDFLAGS,LIBS} (defined by pthread.buildlink3.mk) are passed to the compiler when building/linking the applications, possibly by setting PTHREAD_AUTO_VARS to "yes" in the package Makefile.

#
# This Makefile fragment is included by package Makefiles and
# buildlink3.mk files for the packages that use dlopen().
#
Added documentation.

# It defines the variables DL_CFLAGS, DL_LDFLAGS and DL_LIBS, which
# are also exported into the CONFIGURE_ENV and MAKE_ENV environments.
#
# Package-settable variables:
#
# DL_AUTO_VARS
# When set to "yes", the necessary flags are added automatically
# to CFLAGS and friends.
#
# Default: no
#
# Keywords: dl dlopen
#
Define DL_{CFLAGS,LDFLAGS,LIBS} as compiler/linker flags for building or linking code that uses dl*() functions. Also re-structure a bit to pave the way for a future dlopen.builtin.mk that handles -ldl on some platforms and dlcompat on Darwin.

Simply and speed up buildlink3.mk files and processing. This changes the buildlink3.mk files to use an include guard for the recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS, BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of enter/exit marker, which can be used to reconstruct the tree and to determine first level includes. Avoiding := for large variables (BUILDLINK_ORDER) speeds up parse time as += has linear complexity. The include guard reduces system time by avoiding reading files over and over again. For complex packages this reduces both %user and %sys time to half of the former time.
