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